Ok, top dawg, here's my final thoughts/setup/questions. Let me know what you think and thank you for all the help!
- head unit: love the price point of the pioneer fhx500ui, but it only has 2 sets of preouts.......im looking at the kenwood dpx300u for a few dollars more because it has 3 sets - if im hooking up a 5 channel amp (see below), won't i need 1 set for the dash speakers, 1 set for the door speakers and 1 set for the sub? the rear speakers can just be run off the head unit....i will not be keeping my steering wheel controls (extra $$ for kit)
- amp: 5-channel, either precision power p900.5, precision power i640.5 or kenwood kac 7005ps....all should match well with the 4 ohm speakers i list below as well as the sub.....question - max rms for the 3.5" speakers is only like 40 rms.....will that be a problem if the amp is 70 or even 100 rms or should i look for something (like the kenwood) that's around 40 rms?.......after further reading, i might very well go to the separate 4-channel and mono amp for the sub....i won't be installing anyway, so no need to keep it ultra simple anymore
- speakers: polk db 351 for dash, polk db 691 for doors and polk db 651 for rears....might go to the JBL GO line here if the $$ are significantly less.......or maybe even pioneer's lower to mid lineup
- subs: (2) image dynamics 8" regular subs, dual-voice, and will wire them for the 4ohms......quick question though that might have me change to wiring them to 2 ohm or even to Sundown depending on my amp choice - can i run 4 ohm speakers and then a 2 ohm sub on the same 5 channel amp if i decide to go that route? i've read you can.......i'll also get a custom box from ebay made for dodge challengers for this for my rear trunk
- installation - any idea how much this all might cost to install? i'm thinking, with wires, etc., $400-$500 or so
- challengers have a roughly 150-160 amp alternator......any problems running either a 4 ohm or 2 ohm setup with the above? do i even need the big 3?
that all sounds good. i would amp the door speakers and the rear speakers and then run the 3.5" speakers off deck power. then you will be powering all speakers properly. tune all to match the speakers powered by the radio. the radio will be able to power the small 3.5" speakers better than the larger rear speakers. then the doors and rears and subs ran off the 5ch amp will work great.
