Which are 6x9 car speakers making the most bass?

Car Audio Speakers - 6.5" 6x9 Subs, Crossovers?

• Hey, I have the following speaker setup : Fusion CP-AW2120 Dual subwoofers with built in amplifier 2x Soundstream SF-693t 6x9s 3-way in the rear deck of my car (100rms per) JVC KD-326 Headunit 2x 6.5" Soundstream SF-652T 2-Way each in front doors (60rms per) 2x Basic fusion tweeters in rear of car The 6x9s, tweeters & front 6.5" speakers are all running on car battery and are not externally amplified, they also have no crossovers. The 6x9's are currently hovering about 2-3 inches above the rear deck as I haven't yet cut into it as I will be changing cars soon. I'm not really happy with the sound i'm getting from the setup (not the subs) at the moment although i've been told the 6x9's I have are actually really good. To make the most out of my sound system assuming the 6x9s are cut to fit perfectly in the rear deck would I need to amplify both 6x9s, front speakers and tweeters and would they all need crossovers also? If so would it be best to get a amplifier powering the 6x9s (they are 100rms each) for example at 100rms or would I need to underpower them to around 75rms? Would I need everything my setup is made of ran on crossover? And when the setup is complete should I be turning bass off the 6.5" speakers and 6.9" and leave bass to the subs only or should they all have bass turned on? Thanks!

• Answer:

  Your best bet it to externally amplify the 6.5s and 6x9s. Most good 4 channels will have decent xover settings. I'd get a nice 4 channel and run the 6.5s & tweeters off the 2 front channels and the 6x9s off the rear. You should make the front channels run on a HIGH PASS FILTER (HPF) set to about 120hz so it will not play below that (maybe 100hz if you want a little more midbass). For the 6x9s, you should run either HPF or FULL (meaning it plays both high & low notes). If on full, make sure your 6x9s can handle the bass. NO BASS BOOST! Question: Your 6.5s, are they coaxials or a component set?
