check out ebay, they always have real good prices. i just got 4 of the kenwod KFC-P507 component speakers from ebay for about $185 (including shipping) where crutchfield wants $160 for just 2 of them

 

Dont use Hifisoundconnection.com, they do have great prices, but I have been waiting a month to get my sub. I try to call and they never answer, they say leave your name and number and they will call you back, they have still never called me back, and I have called about 6 times now. 2 weeka ago I emailed them, and they told me it would be here in just a couple of days, well that was 2 weeks ago, and still not here, so I emailed them last night and they said it would be here next week, and still no excuse on why it is taking so long, and not even a sorry, so dont go with them, still not sure if I will get it next week or not!

 

Thats the main reason I dont buy car audio over the internet. If I cant buy something from someone face to face, 9 out of 10, I dont buy it.

 

I've used sonicelectronix and they're very good. Bought a Panasonic Strada ($1,000 nav unit) and after reading the owner's manual I decided I didn't want it. They didn't give me any problems with the return and credited my card back very quickly.

Crutchfield has amazing customer service but their prices suck.

 

I have used Hifisoundconnection.com and didn't have any issues with them. I do alot of internet shopping for parts. I ususlly ask first if a part is instock if I'm looking to get it quick.

 

I bought some polk components back when I had my **** probe from sonics. Good service time, cheap prices, good stuff. I would look here for more system adivce:
