I just hooked up my new subs to my soundstream amp which I had running had 1 ohm, but now it is at 2 ohms. It was playing ok for a while, little quiet but sounded good, then it cut out and now it just makes this constant thumping sound going in and out of protect mode immediately. It still does it when no rcas or speakers are hooked up. Thinking I might have fried the amp, but have no idea why? Any suggestions?}
Amp doesn't have external fuses and id like to avoid taking it apart if I can help it. Battery fuse is good, power and ground good. Maybe a loose speaker connection in the speaker box? But it seems like it wouldn't go to protect when the speakers aren't plugged in
I know this wouldn't make much sense since you said you haven't had any problem for 3 years but maybe your ground has just became a little loose? It's always worth checking, just a thought.
I'm sure it is repairable but probably not worth the money or time. I had an amp that fried on me due to "over current" and it did pretty much the same thing yours is doing but only mine didn't make a thumping noise...the protect light just kept blinking on and off. Do you have any friends who would let you use their amp to test and make sure it is your amp and not something else?
I understand but, no risk = no reward. I wouldn't imagine that just by hooking the positive, negative, and remote wire to the amp would damage it. I mean all you need to do is see if the different amp turns on without going to protect.
