remote turn on lead two amps

If you're using/controlling more than 2 amplifiers, it is (in my opinion) much better to use a relay to control the amplifiers. Because of the two fans I added a relay. Or you didn't check continuity with a meter. The dc offset option does not turn on the amp. speakers wires makes a difference. I will be putting in a relay soon. One wire is for the power antenna, and the other is the amp turn-on lead. the remote wire is for powering on the amp. It is showing less than 1 volt. With the ignition in the OFF position, there should be no voltage. I forgot how much I love that site. Do you just connect the wires to the same remote screw on the amp when you do this? No problems. The first applies if you want to connect multiple amplifiers to a single speaker or pair of speakers, and use only one amp at a time. Although that could be the problem, you wouldn't know because you didn't test each wire end one at a time to the same amp while the wires were still connected. Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times. It isn't a bad idea to put a 500mA fuse inline with the remote wire but that is true even if you are only hooking up one amp. Where would you put a relay? Some amps have them built in, mostly car stereo amps. If your connected to constant power for your remote then I would at the least run it form your OEM Remote turn on lead. A relatively common problem is installing an amplifier with a factory head unit or other head unit without a remote turn on wire (or a burned out circuit). I am running two different amplifiers in my car. Don't make the same mistake yourself with car audio amp turn on leads and power antenna outputs, See how the 2 interact very differently. most times i take the end of the remote wire, and another piece of wire (going to the 2nd amp) and twist them together, put them into the remote input on the amp then secure it. all the remote is, is a 12V current going from the head unit to the amp telling the amp that the HU is on. One is 1000w max (300 RMS x 2 @ 4ohms) and the other is 300w max (50 RMS x 2 @ 4ohms). What if I'm just running 2 amps, 1 for front and rear and the other for sub? I need a remote signal to turn the amp on when the ignition goes on... FYI - don't use the lead fromt he HU to the amp/changer, as you will pull too much power than the HU can handle and damage the HU....just run a new lead â¦ The HU also powers a disc changer and DSP. Locate the remote turn-on lead behind your radio (usually a blue and white wire), and connect the turn-on lead from your amplifier wiring kit to it. Question 1. It could be an insufficient power supply instead and so a relay would be needed. If you can't find a remote wire from the HU, You can use a switch. the blue/white off of your alpine is a low current (.1 or .3 amp) 12 volt turn on lead that is made as a turn on switch for an amp. the relay does not power the amps. I run 4 amps and have never had ANY problems for 5 years now. as i haven't seen a relay before... aside from being able to power up devices with little current, it also acts like a power distro block? The Little Dual allows me to use each amp independently, while giving me the option to play through both amps at the same time. I had run a single remote turn on wire from the head unit to the amplifier and all was well. The remote wire acts essentially like your finger flicking a switch, where your finger is battery power, and the switch is a mechanism inside the amplifier. You should be OK turning on two amps with one remote wire. Hence the term "remote turn â¦ Aftermarket head units provide this but it is recommended that you do not connect more than 1-2 components directly to it. Neither amp turned on when power was applied. I would wire in a switch on the wire you inserted between the power input and remote, so you can turn it on once the invertor is powerd up. Then turn the ignition to the ON position and test the same way again. Remote Turn On. I turned the key on, and neither amp came to life. Others draw a little more. Now, I am installing a second amp. if you supply it with any 12v+ the amp should work. The remote wire in the back of my radio did not work in my Jeep. Watch as Allyn of Sonic Electronix explains how to turn on your amp if you have a factory stereo without remote wire. A Bosch type 30 amp SPDT (single pole double throw) relay is what you need. The remote turn-on wire usually comes from the radio, in which case your amplifier won't turn on if the radio isn't on. What brand of stereo do you have? • Copyright © 1999-2021 the12volt.com, All Rights Reserved. :woot: that means your system won't sound good. the remote wire purpose is to signal to the amp to turn on or off , via voltage signal. I hooked up my amps this afternoon, and I tried splicing the turn on wire into two, by twisting the wire around the original, and then soddering them together. So I put a toggle switch up front, ran one wire to power, and the other wire to where the remote wire is suppose to be anyway. Be sure the positive lead is touching the wire strands inside the jacket of the remote turn on wire. Got 30' of 16 gauge cheapo wire for $3. so. I am not sure why the power supply would be insufficient, unless the splicing reduces the voltage that much. then you could use almost any switch that you can mount hidden or in dash. The two isolated transformers inside the Little Dual take care of the ground hum normally caused by using two amps. you can pick up a relay at your local Radio Shack or on partsexpress. Relays are only required if you are going to be using substantial amounts of current (over 200-500mA). Now, I am installing a second amp. While in the ON position, there should be 12+ volts at the remote turn on wire. Has worked dozens of time for me. Looking at the back of the relay, you'll see 3 posts (right, left, bottom) going straight up and down and then 2 others (top, center) going left to right. All amplifiers in the system will need a 12 volt signal that letâs them know when to turn on. Sorry for all the questions. It doesn't need to be as thick as the power and ground wires (18 gauge should be fine). The signal sensing does turn it on but when I turn the radio off the amp turns off and on and doesnt stop turning off and on. The last wire you need for powering the amp is a turn-on lead. This is because a head unit turn on â¦ Anymore than that, you will need a relay. Come join the discussion about capacitors, amplifiers, subwoofers, marine and automotive audio, troubleshooting, and more! A forum community dedicated to all mobile audio enthusiasts. If I need a relay, where would I get one? i just use a barrier strip as a "distrubution block" and ive used relays. There should be a fuse (equal or greater than the combined rating of fuses on the amps) no farther than 18 inches from the + battery terminal. This is also known as an A/B/Y configuration. 1) Bad turn on lead coming out of your HU 2) Amp needs more current than normal to turn on (less likely) 3) Turn on wire has a kink or bad connection somewhere along the run Most remote turn on wires can provide at least 150mA of current for turn on purposes, enough to turn on at least 2 or 3 amps as each amp takes only a few tens of mA to turn on. i was just going to splice a wire and use that, since i dont have a designated wire for turn on lead. so this will work. My last big stereo had two amps and two fans connected to the remote out. The blue wire coming off your amp is the remote turn on lead, connect that to the blue/white wire coming off of your alpine hu, which is your remote turn on lead. Not likely. ive ran 2 amps, eq and xover from the HU remote with no trouble. I had run a single remote turn on wire from the head unit to the amplifier and all was well. I'm probably just an idiot, but I am having issues getting my single turn on lead split into two for the two amps. JVC KW-HDR720, Audiocontrol EQL, HAT Imagine 5.25 Mids & Morel Maximo tweets, PPI 900.4 Amp, BA 6X9 Rear Fill, Boston G310 sub in 1/2 cu ft sealed -. "The remote input current for amplifiers varies with the amplifier and the model. Today I took the original turn on lead, and a second wire and attempted to splice them together by wrapping the wires around each other, and then soldered them together. Watch as we explore the functionality of an amplifier remote turn-on wire. Daisy chain the remote turn on, relay, or just crimp both to the (blue/white wire) remote lead on the hu? I am still pretty sure it was the connection, but of course I could be wrong. As it is I can't really understand your post. The upper limit of a properly functioning amplifier is approximately 50ma (0.05 amps). The second and third apply when you want to connect two or more amplifiers to your system and use them at the same time, each amp powering a different set of speakers, with one of them usually used for a subwoofer. ive had good luck with both. quite pointless if u ask me. So therefore I need to find a lead to tap into that switches on when the ignition is turned on. Head Unit Has No Remote Wire . Well I noticed a pretty significant increase in SQ once I crossed out Road Gear and wrote in Monster! Then connect each half of the cut remote wire to each of the 2 connections on a toggle switch. well, i have a stock deck for right now and need to know something, with all the cables leading into the back of my deck, will any of the blue wires work for attaching my remote turn on lead? I ran one end to one amp and the other end to the other amp. Even my 2000 Iimpala has an OEM amp If your radio don't have Remote lead. If it has one, there will be a bridging switch to enable it. Basically, I ended up with a "T" connection. i've just used the REM lead and split it into 3 leads to turn on 3 amps back when i had my all JL system and had no problems. If you haven't done it already, I highly recommend this: 20-pin combined wiring Harness for Subaru Impreza, Forester, Legacy, Outback, Tribeca It is a breakout harness that goes in between the car side connector and the head unit connector. To check if the connection was faulty, I basically spliced the original wire back together again and connected it to one amp and then the amp turned on. Apparently mine is not sending a big enough signal when I turn on the stereo so my amps aren't turning on. the remote wire comes from the back of the HU and goes to each amp to turn it â¦ Thanks for the links Bodega, I have the PG TiDD10 & TDD5 for my system & LOVE it. An Amplifier on the stock radio.. I need to run turn on leads to both amps. The days when amp remotes took a lot of current are loong gone. It runs from the remote turn-on lead at the back of your receiver to the remote terminal on the amp. Yes that's the one. I've had 1 power acoustik and 2 different Pioneer amps, neither drew more than .2 amps. So, it was my splicing job that was at fault. That, wtf? In using the relay to switch on my 3 amps, BLA and SXRC I should do the following: doesnt matter either way will work depends on who you ask. It looked kind of funky, but it should have been a good connection, or at least I thought. I will try a new connection tomorrow, and see what happens. installing a remote turn on lead for my amp? BTW I found the best surpluss store where I got the realy from today for only $1.50. When I connect the REM turn-on wire (2 REM wire from amp, to 1 wire from the head unit), 1 will work but the other shuts-off. I need to run turn on leads to both amps. Does anybody know why this happen? JavaScript is disabled. please correct my impression, if im wrong. the relay is only used for the small remote turn on wire. Even if either had drawn 10 amps, it might draw 10 amps for a fraction of a second and then the fuse on the deck would blow. I cut out my splice and butt connected the wire into a single wire again, and connected it to one of the amps. to wire a switch to your amp you need wire the 12+ Connection on your amp to the remote on your amp. Well I got it wired up and it works like a champ. Today I took the original turn on lead, and a second wire and attempted to splice them together by wrapping the wires around each other, and then soldered them together. I had a single amplifier running my sub. The turn-on lead from your HU (head unit) will power two amps, no problem. So the amplifier doesn't stay on 24 hours a day you need a way to turn it on and off remotely. So, it was my splicing job that was at fault. I didn't try piggy backing the wire from one amp and then from that amp to the other amp. if you connect the blue wire off your amp to a switched power, you may get a buzzing or humming â¦ I run 6 amps off of the eclipse remote turn on w/o any problems. Some draw minimal current. Meter the switch lead at each amp. If you still have the amp â¦ If the remote turn-on wire doesn't have power, your amp won't turn on. And yes, just tap in and you run it to the amp's remote turn on. but i could be wrong , help i could help Using a clarion cz702 to an alpine mrx f65 and alpine mrx m110. If it gives you trouble, then use a relay. Off hand I dont recall the color, but if its supposed to be for "remote turn on lead" then that is true, you do not have to hook that up to anything until you install an amp. i put money on bad ground or voltage drop. The reason for the 2 separate wires is so you can have the antenna down when it's not needed, and still have the amp switched on when you're listening to a CD. I didn't think to use the multimeter to test the voltage from each end....I'm still learning the electrical side of this. I think I will try this method, thanks.... Not necessarily. I never thought about this type of potential problem until I needed to wire up three amps. Then piggy back the 2nd piece of wire to the 2nd amp. You can cut the remote AMP turn-on wire, but not the main power wire, add an extra length of remote wire, solder them and heat shrink it to protect and seal your wires. IIRC, either Sony or JVC (can't remember which) 2 separate blue wires. In the trunk, you split that piece of 4-gauge w/a fused distribution block to the amps. For a better experience, please enable JavaScript in your browser before proceeding. That's about as clear as I can explain it, hopefully that helps. For 2 amps there's no problem at all just jumpering the remotes together. You need to be more detailed. 10 AMPS on a remote lead? the remote wire is usually between 18-12gauge does pull minimal 5-10amp , reason why remote wires are usually not very big in gauge . Ok, I have a problem. The speaker is connected to the + of the left channel and the - of the right channel. then you just turn off the power invertor to turn it off (not suggested).

Connect terminal #85 to ground, terminal #86 to one of your 4 ends of the remote turn on wire from the head unit, and terminal #30 to The amp that will be switched by the relayed signal (this line, coming from the relay to your amp, is were you will add your toggle switch). I'm running 2 amps and a crossover off my head unit. I went back and checked it and the relay was pretty hot to the touch...given it was 98 stinkin degrees out but still...does that mean anything? The higher wattage amp most likely to shut off. If you experiencing problems aside from this you may consider a grounding problem. You just have to make sure you turn your switch off when you get out of the vehicle. This time, it turned on, so my attempt failed at some point. Once turned on, the amp has to be hooked up a particular way. I cuurently have the remote lead from my deck to the Nak amp, then from there to the MTX amp. personally i dont think that was the issue. Now repeat that process for each of the remaining three relays. Your local radio Shack or on partsexpress current are loong gone and DSP money bad.
