Hi. Pretty long time I'm looking closely to the digital-eliteboard.org. I like this forum. I'm not sure is the "Qbox HD" ight category , but I really need the answer. #2 Could someone help me understand car audio amplifiers? I have a 97 Ford Ecplorer. I put in a Sony Xplod heazdunit. I've replaced all the door speakers with some Pioneer 5x7 speakers, installed two Kicker flush mount 1" tweeters in the front, and have two Kicker CVR 12" subs in the back. I have one Powerzone Crunch 1500x1 amplifier powering my subwoofers, and a 1.5 farad capacitor. Anywho, I'm generally happy with the sound of my car stereo. I would, however, like for it to be louder. Not the bass, I'm happy with that, I wanted everything else besides the bass louder, like midranges, fullranges, tweeters, whatever. So my question is should I bhy an amplifier to pwoer the door speakers that are already in there for more powerful sound, and if so what kind? or should i add more speakers or something?
