i just bought a alpine 7873 cd player, a mtx rt 2120 200watt amp, and (2) 10 inch subs in a box . I am also planniing on replacing the stock speakers but i was wondering how subs sound in a diesel, in terms of the clarity in which you can hear them inside and outside of the car. Also i was wondering if 200watts from the amp would be enough to make the subs be heard in the cabbin ( the deck is 240watts with a bass engine) or should i persue gettinga identical amp and bridgeing them together? thanks
