I need to run turn on leads to both amps. As it is I can't really understand your post. Because of the two fans I added a relay. but i could be wrong , help i could help 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. 10 AMPS on a remote lead? The remote wire in the back of my radio did not work in my Jeep. If you still have the amp … What brand of stereo do you have? A Bosch type 30 amp SPDT (single pole double throw) relay is what you need. For a better experience, please enable JavaScript in your browser before proceeding. No problems. Be sure the positive lead is touching the wire strands inside the jacket of the remote turn on wire. so this will work. Not likely. 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. if you supply it with any 12v+ the amp should work. Using a clarion cz702 to an alpine mrx f65 and alpine mrx m110. BTW I found the best surpluss store where I got the realy from today for only $1.50. I ran one end to one amp and the other end to the other amp. Got 30' of 16 gauge cheapo wire for $3. I cut out my splice and butt connected the wire into a single wire again, and connected it to one of the amps. I'm probably just an idiot, but I am having issues getting my single turn on lead split into two for the two amps. If it gives you trouble, then use a relay. 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. 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). What if I'm just running 2 amps, 1 for front and rear and the other for sub? 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. IIRC, either Sony or JVC (can't remember which) 2 separate blue wires. If the remote turn-on wire doesn't have power, your amp won't turn on. Now repeat that process for each of the remaining three relays. please correct my impression, if im wrong. Come join the discussion about capacitors, amplifiers, subwoofers, marine and automotive audio, troubleshooting, and more! Apparently mine is not sending a big enough signal when I turn on the stereo so my amps aren't turning on. Then piggy back the 2nd piece of wire to the 2nd amp. Now, I am installing a second amp. So, it was my splicing job that was at fault. Even my 2000 Iimpala has an OEM amp If your radio don't have Remote lead. 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? So the amplifier doesn't stay on 24 hours a day you need a way to turn it on and off remotely. I had a single amplifier running my sub. It looked kind of funky, but it should have been a good connection, or at least I thought. I never thought about this type of potential problem until I needed to wire up three amps. 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). Head Unit Has No Remote Wire . 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 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. I didn't try piggy backing the wire from one amp and then from that amp to the other amp. the relay is only used for the small remote turn on wire. Where would you put a relay? 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. All amplifiers in the system will need a 12 volt signal that let’s them know when to turn on. Basically, I ended up with a "T" connection. I am still pretty sure it was the connection, but of course I could be wrong. I've had 1 power acoustik and 2 different Pioneer amps, neither drew more than .2 amps. personally i dont think that was the issue. the relay does not power the amps. The HU also powers a disc changer and DSP. 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. One is 1000w max (300 RMS x 2 @ 4ohms) and the other is 300w max (50 RMS x 2 @ 4ohms). Some draw minimal current. I'm running 2 amps and a crossover off my head unit. 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? One wire is for the power antenna, and the other is the amp turn-on lead. I need to run turn on leads to both amps. 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 didn't think to use the multimeter to test the voltage from each end....I'm still learning the electrical side of this. The last wire you need for powering the amp is a turn-on lead. I will try a new connection tomorrow, and see what happens. In the trunk, you split that piece of 4-gauge w/a fused distribution block to the amps. The two isolated transformers inside the Little Dual take care of the ground hum normally caused by using two amps. The Little Dual allows me to use each amp independently, while giving me the option to play through both amps at the same time. the remote wire is usually between 18-12gauge does pull minimal 5-10amp , reason why remote wires are usually not very big in gauge . 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. If your connected to constant power for your remote then I would at the least run it form your OEM Remote turn on lead. It could be an insufficient power supply instead and so a relay would be needed. If I need a relay, where would I get one? Well I noticed a pretty significant increase in SQ once I crossed out Road Gear and wrote in Monster! 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. Yes that's the one. The higher wattage amp most likely to shut off. 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 am running two different amplifiers in my car. 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. I cuurently have the remote lead from my deck to the Nak amp, then from there  to the MTX amp. then you just turn off the power invertor to turn it off (not suggested). So, it was my splicing job that was at fault. :woot: that means your system won't sound good. 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? You just have to make sure you turn your switch off when you get out of the vehicle. Meter the switch lead at each amp. 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. speakers wires makes a difference. Thanks for the links Bodega, I have the PG TiDD10 & TDD5 for my system & LOVE it. "The remote input current for amplifiers varies with the amplifier and the model. And yes, just tap in and you run it to the amp's remote turn on. Question 1. The days when amp remotes took a lot of current are loong gone. the remote wire comes from the back of the HU and goes to each amp to turn it … • Copyright © 1999-2021 the12volt.com, All Rights Reserved. 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. It doesn't need to be as thick as the power and ground wires (18 gauge should be fine). 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. Has worked dozens of time for me. This is also known as an A/B/Y configuration. Watch as Allyn of Sonic Electronix explains how to turn on your amp if you have a factory stereo without remote wire. 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. Technical & Advanced Car Audio Discussion, IDQ12D2v3/Dyn MW160/Lotus RM110/Seas neo Alum, http://www.teamrocs.com/technical/pages/relay_basics.htm, ftp://208.187.38.55/Phoenix_Gold/Manuals/Accessories/TiDD10_TDD5_Manual.PDF, System Design: Help Me Choose Equipment For My Car, VerticalScope Inc., 111 Peter Street, Suite 901, Toronto, Ontario, M5V 2H1, Canada. installing a remote turn on lead for my amp? This is because a head unit turn on … The speaker is connected to the + of the left channel and the - of the right channel. An Amplifier on the stock radio.. I turned the key on, and neither amp came to life. Does anybody know why this happen? It is showing less than 1 volt. I am not sure why the power supply would be insufficient, unless the splicing reduces the voltage that much. It runs from the remote turn-on lead at the back of your receiver to the remote terminal on the amp. ive ran 2 amps, eq and xover from the HU remote with no trouble. The upper limit of a properly functioning amplifier is approximately 50ma (0.05 amps). I run 4 amps and have never had ANY problems for 5 years now. quite pointless if u ask me. the remote wire is for powering on the amp. Relays are only required if you are going to be using substantial amounts of current (over 200-500mA). JavaScript is disabled. 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. 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. 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. Ok, I have a problem. 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.
