Ok I'm going to upgrade my system...and want to make sure it'll work out ok...

Head Unit
Alpine CDA-7897 OR Alpine CDA-7998...which one??...I was planning on getting the 7995...but my friend is most likely gonna get that one...and i don't wanna have the same one as him..i wanna get something better than he has cuz he has a teg and he thinks his teg is hot shit...so i have to do better than him...also Austin or StreetEffectz...can you or anyone else get me a deal on this one of these head units...
Alpine CHA-1214 12 Disc CD Changer

Speakers
Focal 165W 6.5" Component System
Focal 6x9" POLYFLEX 2-way Coaxial Speaker

I am having trouble finding an amp for the speakers...the main reason is because I don't know the difference between 2 ohms and 4 ohms...should I wire the speakers above at 2 or 4 ohms...also would those Focal 6X9" sound good...i know focal makes great speakers...but are there any better 6X9"s out there...thanks to anyone who helps...

Also one more thing...what is a good place to find good 0 awg wire...

I can get the decks (either) and the changer for good prices, plus ship them free. I'd just pick the one that has the features you like, fuck your friend... you have the better car!

I'd wait for the new Boston amps to come out... my guy went to CES and said they are absolutley incredible! Tomorrow i have to talk to him to get some model/pricing info.

Either that or the new alpine's that are out (almost) the mono blocks are out now, and the 4 and 5 channel will soon be out, also amazing amps.

 

thanks for your help...but can someone answer...

1) Where can I find 0 awg wire
2) Whats the difference between 2 ohm and 4 ohm...once I know this then I can find an amp for my Focal 165W...thanks..
