sub goes crazy for a couple seconds... amp into protect... suggestions?

[spencer321 10+ year member]

checked the power and ground... its steady, plus my highs amp is off the same distro block one foot away and that amp is perfectly fine. Pulled the sub, Dual 4ohm coils read 3.9 on each coil, checked and double checked all my wiring, it all seems fine, the only thing i haven't gone through is the signal wire itself... is it possible for a short or a bad signal wire to cause this problem?

symptom: turn the car on plays fine for a minute, then a couple really loud pops and protect

do you have another amp you can try?

no its the amp... i started workin on it, been disconnected for a few days, now it goes straight into protect, so i disconnected everything and hooked it straight to the battery and jumped the remote to the positive, straight into protect...

so i opened up the back of it... what am i looking for? or should i just pitch it and say to hell with it?

look for any burnt spots....if you don't know what you're doing amp repair can be pretty hard

Take the amp to a car audio shop and get them to test it in front of you...Some charge nothing at all..my advice to you..Best buy/local shops/ect???
