u may want to upgrade that amplifier. those components will sound much better with a little more power running into them. the x-overs rob alot of the power you send thru them, so if you can by-amplify them i would get a 4ch to reun the components up front and put the dinky pioneer amp on the 6x9's. if ur not really that into audio scene, ull prolly be very happy with that setup. but if your trying to really make an impact on ur sound i would replace it all and go with some boston or alpine speakers, amplified of course with a modest sub, single 10 in a slot ported box maybe.

of course all this teeters on theh head unit. if your source unit is crap, dont bother with anything unless your going to go big on external processing ($$$$$$$$)

let me know if you have any other audio questions, i came here to learn about motors, but i can help with stereo/security questions all day!
