-Amplifier Remote Wire-

[Jiggaman]

I mounted this amp behind the seat of my truck. If the truck sits with the amp on too long the battery goes dead.

It was getting to be a pain to reach back there and switch off the amp so I added a remote control wire. Now it operates exactly like my subwoofers. It all turns on and off with the ignition key.

I found the power switch wire inside the amplifier and put a relay in the circuit. (Just find out how much current flows through this wire and choose the rating of the relay contacts accordingly). In this case I used a 5amp relay from radio shack.

I cut the power switch wire inside my amp and soldered the ends to the normally open contacts of the relay.

This relay has a 12vdc coil. I soldered one side to ground. The other side of the coil goes to a wire outside the amp for controlling it.

Now if you put 12v to the remote wire it will turn the amplifier on just like most subwoofer amplifiers work.

This should be able to be done easily to most amps as long as you use the appropriate relay and wire it correctly.

Maybe this helps someone with an idea?

Cool post!

Very usefull info

[Punkin Head]

I like the idea of that, I think I will try it out in my moble.

I was wondering how to do that. You've had no problems with it?

[Jiggaman]

I have had no problems at all. It works perfectly. This should be able to be done in most amps as long as there is enough room in there to mount a relay and you are able to break the power switch wire.

The only thing to get right is the relay. In my amp, the power switch carries very little current. You can tell by how little the wire is and how dinky the switch is. I figured a 5A relay would be more than enough. If you are not sure you can measure DC amps with most multimeters.

If for some reason your power switch wire carries more current, use a big enough relay thats all.

sounds easy enough, thanks for the info, Jig.

good luck with everyone's projects!

my switch does'nt work on my palomar 225 it stays on all the time hope it don't kill my battery but it's been like this for over a year.

[mudder]

those switchs always brake mines broke too.

Was thinking the other day about making a remote for an amp..
but you think you could extend all the control panel wire. Make a smaller remote housing for the controls, & have all of them in a remote location? just a small box switch box under the dash...

[Jiggaman]

It depends how the wiring is. If the switches are part of the face like mine, just extend the wires using thermostat wire or rotator control wire or something.. I'm not sure if you would need to shield it or not. It might depend on the amp..

There is allways room for experiments. Thats how I learned the little bit I know.

[Madhadder1558]

cool,
yea, all the controls are on the front, like yours..
I was looking at some thick clear hose today at the autoparts store I could use to run the wires throught to keep them from getting damaged..
Think I give it a try, & let you know..


:Peace!:

10-4. Yes I would be concerned about something shorting in the wiring harnes you are going to make. It could make something go horribly wrong inside the amp or burn up a solder trace or something like that...

Good luck with your project.. 73 Jiggerman

i was thinking about doing the same thing with a relay ecept insted of gitting a 12v of the ignition i was gonna run a live feed into the cab and mount it to a toggle switch on my overhead mount i made for my grant and run the line down to under my seat where my amp is

[Jiggaman]

yes that would be nice to be able to turn the amp on and off from up there instead of reaching under the seat...
