Hey i have a Power Acoustik LT1920-2 on a Kicker SoloBaric L7 15". i was on my way home today not pushing it real hard or anything and when it hit it got about halfway through the note(the note was a bass drum in a rock song) and it lost power. it did not shut off, it just couldn't really push the sub anymore. when i got home i looked at the red/green power light. it was orange until the bass hit then it turned red the went back to orange until it hit again. if i unplug the audio cables the light turns green. does anybody know what it could be?


Thanks,

-Chris

 

wow that sucks. hope nothin happened to it.

 

have you checked all of the fuses in the system?

 

yeah

 

the amp might have overheated. does it have a fan on it and where is the amp at in the truck.

 

no fan, laying on the floor behind the driver seat. it was hot i might have forgotten to mention that. it had some papers and a shirt laying on it, but not much.

 

yeah, sounds like its overheating to me. im no expert by any means, but try to not put anything over it. The more air it has, the better.

 

yeah, i didn't mean too. i figured that is what happened, but wasn't 100%. does anybody know what part in the amp actually goes bad when it overheats? i have it apart now and i don't see any burnt circuits like there was a short.

 

i had a amp that would turn off when it got a bad power flow coming through the line. if your running a 15" sub and your amp is runing anywhere over 1200Watts then u need at least a 4 gauge wire if not a 2gauge. cause it can cause real problems if you dont have the right wires

 

i have 4 guage now. i have had this amp in there for about two months w/o a problem. i wasn't pushing it hard when it quit working.

 

Sounds to me like overheating or a bad ground. If it has never overheated befoer, double check your ground wires.

 

Doesn't sound like a bad ground to me as it wouldn't work properly from the start.

Overheating maybe but if a amp goes into protection, that usually means the gain or bass boost is set too high and the amp is clipping. so how high do you have your gain and bass boost set to? If you turn it down a bit and then see if it does it again. When you plug the amp wires and it shuts off and then you unplug it and it is normal, it seems like amp settings to me.

Have a check, any amp will get really hot but not so it you can't touch it. Make sure air can flow around it and you should be good.

 

okay i'll mess with it a little later and let you know whats up.

 

I was thinking maybe something like a bolt vibrated loose.

 

If its a ground problem, wouldnt the amp not turn on at all? he said it turns on so...

 

i was thinking maybe a solder broke loose internally. that has happened to a guitar amp of mine. i kinda hope thats what it is if it isn't just adjustments.

 

no if it lights orange like you said my amps did that all the time it overheated. you should be fine just make sure you have nothing on top of it. you should be fine. i deal with this stuff all the time so.

 

well thanks everybody, it was just overheated. i had tried that night after it cooled off a bit, but it didn't work so i brought it inside overnight and opened it up. i just went out and tried it again and it worked fine. i feel like an idiot because i mean this isn't my first run around with an amp. and i have another question if you would. my SoloBaric is dvc and the amp is bridged two channel. i was wondering how it should be wired to make it 4ohms, series or parallel. i was assuming series, but i am not sure.

 

you have the question i got the answer,


wire your sub to a higher ohm so its not drawing alot of power from the amp and should solve your problem

 

so...like this?

 

yup, youll get a little less boom and alot more clarity

 

okay, thanks for your help.
