Is the amp "squished" between the sub box and seat or anything?

Whats your electrical like? what amp alternator? any extra batts?

Good grounds? Solid wiring?

I had the same amp, over heated on me at least 2 times a day, considerably more if I drove for a long time. Did the same thing to the guy I sold it to too.

Don't trust a company selling a 1200w amp for $150 to make an amazing amplifier..?
