I have a sony explode amplifier. I have a 5 guage wire running from my battery through a 100 amp fuse to a distibution block. from there I am running a 9 guage wire to my amp. I have a 9 guage wire running from my amp to the chassis for ground. That stupid amp has a protection on it. Green light is good, red light is bad. I can't get rid of that red light! Can somebody please give me an idea of what's wrong?!

try re-grounding or checking your ohm load.

well something is wired wrong or set wrong. when does this happen? all the time ? under load?(while playing music).

how do you have you subs running to the amp stereo or bridged? what kind of subs? dual or single voice coils?

how did you set your gains? that is not a volume control!

give a little more info

All I have hooked up is the battery, remote, and ground. I tried jumping the remote in case that was the problem, but same thing. I haven't checked any of my levels though. I did run a small 18 guage ground wire direct from the amp to the battery and it worked for a couple of minutes, but then I think the wire got too hot and it went into protection again.

gipetto, do you have any speakers connected to the amplifier? If so, how many? Do the speakers have a single voice coil or dual voice coils? What is the nominal impedance of each voice coil? How do you have them wired to the output(s) of the amplifier?

I did have 2- 8" subs, single coil, I think, but it shouldn't go into protection with no speakers hooked up.

Try connecting speakers to it, then let us know what happens. BTW, why are you running it with no speakers connected to it?

[QUOTE=gipetto]

first it sounded like you have a bad ground and maystill do. but without any speakers hooked to it the amp should only pull a low current to stay idle. the first thing i would do is check your ground. make sure it is the same gauge as your main pos. from the batt.

and that is 18" or shorter directly to a chassis ground. like seat belt mount. clean(scrap) all paint from metal and use correct terminals on ends of wire.

then follow the 12 volt and hook up subs or speakers. why you don't have them hooked up already?

then if you still have the light i would get the amp checked out or your wiring

I was running it without speakers because I took it to the retailer to have it tested, he tested it without hooking up speakers, and I just never bothered to hook them back up until I got it working. It doesn't seem to make any difference when I hook up the subs. BTW I have grounded it to the floor of the trunk, back of the seats, chassis, and to the rear seat mount.

you wrote...BTW I have grounded it to the floor of the trunk, back of the seats, chassis, and to the rear seat mount.

you have multi ground connections? or you have tried all of those? did you clean(scrap) away paint from metal? you didn't say

Sorry :) Yeah I have tried all those locations. I scraped all the paint away. Could it be that my battery is weak?

does the car run? if it does and you have tried the amp with the car running. no i wouldn't .

when you step down from 5 guage to 9 guage what kind of distrobution block are you using and have you checked those connection?

you said you have brought it back and they tested it without speakers? but no light?

When I had it tested he had a green light. I tried running an 18 guage wire ( the only one that I had that was long enough) directly from the amp to the negative post on the battery. I had a green light for about 2 minutes the n it changed to red. I think it was because the wire got too hot. The distribution block I have is basically just a splitter / reducer. the connections seem real good.

well like i said it sounds like your ground is bad. but you've said you check them and followed good procedure. then when you hook up a direct ground to battery it worked,but did you have subs or speakers hooked up? it will make a difference. if no and the wire got hot and went back into protection you have something wired wrong or your amp is bad. probably wired wrong because you have had it tested. but not wrote in stone.

and if you had subs hooked up and it was playing then went back into protection your grounds are insuffient.

check vechile body/chassis ground from battery. right near the battery to body. and from engine to body.

Yeah I had the subs hooked up. I also tried another amp, and it worked ok, but then it didn't have a protect on it. I guess maybe you're right it could be the ground to the car from the battery. I'll check it out. You might hear from me tomorrow. Thanks alot, everyone.

if you tried another amp in the same car. the amp in qeustion is most likly bad. but check those grounds again and get the amp check out again. but you have said alot of stuff that does not quite make sense. let us know what happens. we always like to hear the solution to the problems posted. good luck.

Well, I took the amp back to the retailer it seemed to work fine, I tried in a another car and it went into protection. So I gave up. I got a different xplode amp, wired it up and it works fine. Phew! thanks guys for all your help.
