Broken Amp?

[Dr Juice]

Um, ya, i started listening to my music on thurday afternoon, and then im headed over my buddys house friday night, and my amp dont turn on. Its a JBL p180.2. The red light comes one, then the green comes on, and then fades off and the red light comes back on. Checked fuses and connections, all fine, the amp was pritty hot, could it be over hearting?

Does the amp run after it cools?

that red light is probably a protection ckt. What is it protection from?

i have a proble like that too. i was in my car and my subs were on and then they just shut off and i looked at the amp and the power light was on but the protection light wasent. i checked all the fuses and conections to and there was nothing wrong.

do you have a multimeter?

anyone with a system probelm should get a multimeter and check for battery voltage going to the amp, most problems with amps are because of wiring,
even if you checked both ends (connections) of the cables, in a truck I fixed recently with a similar problem. there was a crimp type butt connector for the remote wire that deteriorated under the carpet, and caused the system to periodically turn on/off
Do you have a power (red) light without the remote wire connected? (green = on) (red = power)
Do you have another working amp you can jumper the remote wire from? (this is how I found the problem on the Truck)

if it was pretty hot the amp was overheating and could have caused damage

"pretty hot" is a relative term, amps get real warm, but shouldn't get hot enough to burn you or anything... Yes, overheating can cause permenant damage, but you should at least test it before buying a new one!

no i dont think so what is it? im new at this stuff, sorry
thanks for your advice and what does a multimeter do. wher can i get one.

[sr20de4evr]

you can find them at hardware stores

you can use them check to make sure the sub isn't blown, the amp is getting power, the amp is getting a signal, the amp is putting out a signal, etc.

It sound like your amp. The reason is b/c your subs are prob 2ohm and when you have them bridged together they create 1ohm. 95% of amps aren't 1ohm stable and you can be just damaging your amp, if its not already.

ya i got new rca conections and it still dint do anything. im so mad. also i didnt have my speakers hooked up yet but i was just listening to my subs, i dont know if not having my 6x9's hooked up had anything to do with it tho. it seams like it is not getting any signal from the cd player but im gona try hooking my amp up to one of my friends system so ill know then if its shot or not. but is thier anything else that could be wrong?

it seems as if i would have to agree with shawn if you ran them in series parrelell then that should fix the problem
