You may want to reconsider placing the amplifier under the passenger seat. If there's any kind of an issue with the A/C system draining (e.g., the rubber drain line in the engine bay has a problem), water will be spitting out all over your amp.Originally Posted by Nayrb37
Factory tweeter location sucks from a SQ standpoint. Why spend $$ on decent audio equipment and then neuter it due to placement? Consider buying another set of A-Pillars and molding a tweeter housing in them or install them in the kick panels (not as good for SQ as the A-Pillar, but a bit stealthier) for better results. I have my tweeters installed in the kick panels, and you won't notice them unless you look for them. I left my OE tweeters in place, but they just aren't wired. To someone none the wiser, they have no idea.You don't have to want your car to shake for a subwoofer to be a fantastic improvement to sound quality. Allow the component speakers to focus on the mids/highs (what they're designed for), and let the sub focus on the lows.Originally Posted by Nayrb37
I'm not a big bass person, and my JL 10W3 getting powered by 250W is perfect. Enough of a "kick" in the seat when it hits, yet is basically inaudible from outside the car. I run a 4-ch amp with 1/2 powering my components, and 3/4 bridged to the subwoofer.
