How much luck have u guys had running the head unit to a amp and 12inch Kickers....I really don't want an aftermarket headunit for reasons im sure you guys understand but wouldn't mind the extra bass....plus could u refer a good amp to luck into to run to the kickers....tx in advance

 

it is most def possible...here are u option...

a. buy an amp that has speaker input...then just tap into ur speaker output...
b. buy a thing-ma-jig that converts speaker level input into rca output...requires tapping into ur speaker output also..

i would highly recommend rf amps...

 

look for a bridgeable 2-channel amp with built in crossover
and speaker level input.
So depending on what impedance your speakers are, you can go 1 or 2 channels and wire them up accordingly.

 

Rockford amps are pretty nice but get PPI, I saw some guy who had 2 12" L7's get a 150 db @ a competition.
