ChevyBoy Posted November 12, 2006 Report Share Posted November 12, 2006 no problem man. id rather than even $20 for a relay then to have to buy a new head unit. or u could just rig a power wire up, put a toggle on it, then run ur leads off of that??? I picked up a relay today. $4.95 and an extra $4.95 for the harness. $10 total. Not bad :- I'm installing it tomorrow morning. good choice man good choice :^ Link to comment Share on other sites More sharing options...
Cuseikan Posted November 12, 2006 Report Share Posted November 12, 2006 Wait what's this about a realy? I have my sony xav-a1 headunit turning on 3 amps. That's bad, it's been doing it for about a year. Link to comment Share on other sites More sharing options...
ChevyBoy Posted November 12, 2006 Report Share Posted November 12, 2006 yea. i only trust a remote wire to turn on 1 amp. i kno some1 who has the remote on the head unit go out off 2 amps. each one of those amps arent receiving the full current to turn them on/keep them on. put a relay on it and u might notice a difference.

Dale Posted November 12, 2006 Report Share Posted November 12, 2006 what would you notice if you have a relay. I still have my remote turn on on two amps, but thats only cause I dont know how relays work :-[ In my opinion, turning on 2 amps is the absolute limit for a H/U. Anything more and I seriously recommend a relay. Here's how it works: A relay is like a switch between 2 circuits. The remote wire from your H/U connects to the relay (and only the relay). So you have your H/U turning on only one thing. The relay, in turn, is grounded and has another 12V feed from the battery. Then it has its OWN remote, which is capable of providing more current to turn on the amps (you could turn on like 10 amplifiers using a relay, easy). So you are basically turning on your amps straight from the battery. But it only happens when you turn on your H/U, because the remote turns on the relay and the relay "turns on" the second (higher current) circuit.

Dale Posted November 13, 2006 Report Share Posted November 13, 2006 Well I installed my relay yesterday. And lemme tell ya. the lights on my clarion EQ and amps used to dim a lot but now not at all. What was happening was that my H/U was struggling to keep everything on but now the relay provides more current. Plus, I like that lil' 'tick' noise it makes when it comes on :^ Link to comment Share on other sites More sharing options...
dmanson Posted November 14, 2006 Report Share Posted November 14, 2006 so i have multiple splices with the one remote wire i have from my cd player also. so where can i pick up a nice relay to control two amps and two tv monitors in my truck? 2-DC 15XLM2 D.7s 1-DC 5K amp (1) XS Power D6500(UNDERHOOD) and (1) XS3000(REAR) 3 runs 1/0ga for power and 2 runs of 1/0ga for negative.

A reputable electronics parts store should have it. Make sure you look for one with a "front-end" rating lower than 300 milliamps and a back-end rating of several amps....Meaning....one which needs a smalll amount of current to switch on, but can provide ENOUGH current to your amps once it's on. :^ Link to comment Share on other sites More sharing options...
