Need Help with my projectdunno:
Right now I'm in the planning stages and have more questions than answers.

My Current setup is stock Head, Stock speaker amp, Sundown Audio SA-10 (Just recently purchased after my Polk SR-10 **** the bed). Powered by a Polk Audio PA1200.1

My next step is to improve front stage. My Question is can I just start with replacing the stock Bose amp with a 4 channel amp. If so what would you recommend, please keep in mind I plan on buying a set of JBL 660GTi for the Front door replacements. Not sure on replacing rears at the moment but prob a coax setup down the line. Any help thoughts or ideas would are welcomed

 

dont worry about the rear speakers unless you have rear passengers often.
Save the money for the front stage.

4 channel amps come in so many different varieties its hard to pin point one.
Are you looking for a mid priced amp with a lot of crossover features?

Are you opposed to Class D full range amps?

Budget?
