I am putting in a completely new sound system in my 2003 Grand AM SE1. I have bought the speakers, but im looking for the right amps and sub(s).
Front Speakers: PIONEER TS-A4670R 4x6"120watts 3-WAY SPEAKER
Back Speakers: Pioneer TS-A6991R 6"x9" 5-way 460 Watts
Im looking at a Pioneer GM6100F 600W 2/4 Channel amp to power the speakers, but i really want to get an sub (possible two) and another amp to power it. I have 500 to spend the subs and amp, i'll be doing the installation myself (with the help of my techie b/f). Could you please suggest products that i'd be the most bang for my buck. Thanks in advance!
