thanx for the help next question is lets say for the moment i don't want to change my speakers and i want to keep my stock speakers but i want an amp to power up my stock speakers wat would be a good amp. and can sum1 expalin to me how powering the four speakers wit da amp works.

 

NONE

haha... seriously.... i wouldn't put any of those in my car

 

what would you put

 

dls, rainbow, high end mb quart, cdt, probably a couple of others

 

eD, or DLS through eD

 

if your on a budget (300 bucks or less ) then any of those would work fine.
If you have alittle more money to spend and have some money for a nice amp then yes I would go with what Nebster and bruce.

Either way id still try to find shops that sell the brands you are intrested in and have a listen.
Even brands vary from set to set. Some have differant tweeters,crossovers,and woofer and they all will sound differant

 

I run Polk's in my car and am happy with them. My friend runs Alpine Type R's and they sound really good as well

 

CDT makes a nice speaker, but there crossovers are enh but you can get 2 speakers, 2 tweeters and the crossovers for like 330

 

any other amp good for the stock speaker

 

that's sort of a waste to power our stock speakers

 

I would upgrade Mids/Highs and go with JL audio! :D

 

Go to an audio shop and listen to some (all if they have them) of the speakers listed and see what sounds good to you. That's what I did. Got a killer deal on the Polk dbs and installed them in my car. They sound cool to me.

Also, a lot depends on how much you're going to be in your car and if you plan to do any shows. If you plan on doing those things, get decent (medium price range and up) speakers. There is no need to spend gobs of $$$ on audio gear when you're not even in your ride that much.

 

i saw the 10,000 rainbow set up the other day that thing looks hela crazy

get sum focals :D

 

if you're on a budget. Kenwood, Alpine make some really nice speakers for our factory size. The pioneer's while nice, I think they lack the bass without an extra amp. Definitely get to an audio shop and take a listen.

 

Dude get the dynex or insignia they are by far the best speakers! j/p Out of the ones you listed I would go with Infinity, but also look into polk or cdt, those are some of the better speakers in terms of clarity that I have heard at least...

 

out of that list? Infinity and Alpine.

but why limit your shopping to best buy? haha...unless you work there and get killer discounts.

 

phoenix gold rsd's

i put a set in my car on a kicker zx550.2 about 3 weeks ago and they sound amazing.
