wasn't by chance a cheap Chinese amp?
once apon a time long ago
I made the mistake of buying a brand new Chinese amp with XXX rated output, it was 100$ seemed legit, got the amp plugged it in, it went for about 2 seconds, smoked up burning plastic smell an fried itself. (later confirmed it was STUFFED, basically the capacitor wasn't high enough rated for the output or something I was told, disassembled took detailed pics an thats what i was told)
Took it back he wouldn't refund it because it was "badly installed' I was lol prove it, he reckons a loose wire touched the other negative wire an fried it.. I was like F off you cheap XXXX give me my money back, he refused.(that reminds me I have illegal window breaking todo)
brought a decent 2nd hand unit for 50$ installed without changing any wiring an it went first time an never stopped to this day almost 2 years later
fukn dick head trademe sellers. yea yea i installed it wrong its real hard to assemble a few wires you slimey bastard.
cough rant over
p.s dont buy from cheap asain imports places they are dodgey as hell have like a 20% failure rate.theyre not cheap for no reason.DRAGON AUDIO = FAIL
