im looking for help with nearly every aspect of my cars audio system?

sure i'll do it

stereo-----for stereos you have to think about what you need if you want to play mp3 cds get a stereo that plays mp3's if you have an ipod make sure you get a stereo with an auxilary input on the fron so you can connect the mp3...i suggest pioneer, sony xplod and panasonic stereos

speakers-----for speakers you can go online and find out what size your car can fit then choose a brand you like and look at the watts rms 50-100 will be perfect.....i suggest jbl, pioneer polk and infinity speakers

subwoofers-----pioneer premier kenwood excelon mtx audio and kicker make good subwoofers.....choose a suboowfer that'll fit in your trunk and put it in a sealed box because it's your first set up and sealed are the easiest look at the rms power of the subwoofer you want and also look at the ohms is says this on the box

amps-----then you'll need an amplifier to power your subwoofer get an amp that has the same watts rms and ohms as the subwoofer that you have chosen

wiring kit-----get a wiring kit for the amplifier sold at walmart

installation-----take it to your local swapmeet or mom and pop spot they'll charge about 40 bucks for the stereo installation for the harness and installation...you should hook up your own speakers by taking off door panels and what not

the amp installation can be anywhere fron 20 to 40 bucks 45 is a rip off

damb my hands hurt from all this typing

Your best bet would be a local shop or Best Buy. The folks on here would need WAY too much info from you to get a really good answer. And people also have different ideas on which brands they prefer.

for anything you look at buying, make sure you check out this website for pricing. It is where i buy almost all my car audio stuff, cause it is amazingly cheap, but everything is brand new, good quality, not refurbished, and they stock almost all major brands, plus more! GOOD LUCK!

You should go with 12 gauge speaker wire.

That's too much work for any of us to input. Check with your local shops for ideas.
