If it's in proper working condition...not really.
Since it's old, you should counter the offer with about $700. You can purchase almost all of the above, brand new, current model line up, for about the same price. I'd be happy to accomodate.
Here's what I could do.
2 x P2 12" Rockford Fosgate Subs
2 x Rockford Fosgate 6 1/2 Components. *
2 x Rockford Fosgate P4004 Amps. **
1 x Pioneer Premier DEH-P760***
* On the components, you have 6 1/2 in the front, no problem, but your rears are 4" (plus, it'll drop cost).
** Why 2 4-channel amps, You'd be better off getting one 4-channel and 1 2-channel or 1 Mono amp, for the subs(plus, it'll drop cost).
*** This unit comes with a 2 year warranty, and is a Pioneer premier, not a regular pioneer. Better components, warranty, and extra features when compared to the equivalent Pioneer model (7600).
let me know.
