People can hear me comming for 1/2 a mile to 1 mile (5-10 blocks as reference) dependent on time of day and amount of traffic (if i have my stereo cranked up), and i by no means need 8 6x9's to do so.
2 12's @ 1200w will turn more heads then your annoyingly high pitched sound. I have 2x Diamond D3 6.5" integrated component speakers in my front doors, 2x Diamond D3 6x9 in the rear deck, 2x Diamond CM3 12" subs, and im hittin about a 149.5 on the new term lab system.
As for having that many 6x9's in general for the sound quality... must suck, unless you have an external amp powering them. I had those pioneers and i absolutly hated them (which is why my audio is all from Diamond Audio now) and i know theyre rated at about 60w constant, and i know your deck doesnt put out 240w for all those 6x9's, plus whatever you have in your doors.
function over form.
