Infinity Replacement AMP
 

Got a quick question...

2002 Montero LTD with infinity sound. Bought a replacement sub (polk audio 8")

Come to find out when I plugged the new sub in it fried the factory AMP. I'd like to get a decent replacment sub that I can use with the factory head unit/speakers/and new sub.

What do I need in the way of a AMP? Like to stay around < $150

What do I need in the way of a cable adaptor to hook into the factory amp wiring?

How do you wire the new AMP?
