So I got a 8" kicker sub and a precision power amp (not sure about the specs) what should I do with them? I'm thinking a box under the passenger seat for the 8" sub. On a side note I'm running one 12" p1 under the back seat w a separate amp, do I need 2 amps?
your right you could tune the amp for you 8 to hit the mids that the 12's miss and set your 12 to hit lower
you could possibly bridge the power/remote from your other amp to save you running more wires..
I had a setup many many moons ago with two 12''s and two 10''s I though it was perfect having the two picking up different frequency's
<edit> didnt read OP properly >.< . .it would be best to run a seperate amp.. If you bridge off that one amp chances are the subs will not fire at the same time one will be more responsive giving you a cancellation effect in turn you get a messed up sound
