New Speakers

I'm curious what makes you want to go from having components to putting in Coaxils?  You'll get far better results by upgrading to an entirely new component set and being that you already have stock tweeters the install should be a piece of cake.  Trying to install a set of coaxils in addition to your pre-existing tweeters won't sound right and you'd be amazed at the sound improvement with aftermarket tweets.  I recently put the Polk db5250 5.25 component set in my '04 Grand Am and have been really pleased with them.  I would have gone with the db6500 6.5s but I was going to have clearance and fit issues so I went with the 5.25s instead.  I'm not sure if you made the coaxil decision based on cost or what, but you'll definately be more happy with a component set, and you can find them for about the same price if you shop around.  As always, the best way to find out what best suits you is to go listen to them, and Crutchfield is a great resource for doing research, but obviously their prices are a bit high.  I purchased all of my audio equipment (deck, front and rear speakers and sub) from ebay.  I've never had a bad experiance and I buy all my equipment new, not used but at much lower prices.  The 5250s list for $179.00 before shipping on  Crutchfield and I got them for $112.00 with shipping brand new on ebay.  Whatever you decide to do, make sure your speakers are installed right.  You don't have to have them done professionally if you don't want, just make sure you take you time and it never hurts to put some kind of deadener on your doors or at least around the speaker opening.

Like I said, I can only speak from personal experiance, but I bought the Polk 5250s, a set of Alpine type S 6x9s and my Alpine type S sub all from ebay, all from different sellers, and my previous deck was from there as well.  All of them came in their boxes, brand new with all the paperwork and parts.  The only risk you run is that generally they're not certifed resellers and as such can not usually offer the factory warantee, but will generally compensate with their own.  Those sellers live and die by their feedback, so as long as you buy from a seller with good feedback who people have said is reliable then you should be set.  I personally won't buy from any seller with less than close to 1000 feedback.  If you're still hesitent, Cardomain.com, Amazon.com, Crutchfield.com, Shop.com, Circuitcity.com and Millionbuy.com all stock Polk.  I used Circuitcity.com with in store pickup for my sub box and saved $40, just by ordering online and I got my current HU (pioneer deh-p5800mp) at Cardomain.com.  Their shipping was a bit slow, but they had the best price.

And I'm not saying the Polks will be the perfect speaker for you, you'll stil want to go and listen to some other brands to compare and if you decide on something else, your purchasing options may be different.  If I were you I'd also look into Alpine and Infinity.

If anyone is still interested in an opinion on finding good new product online at extremely low prices I have had excellent business with    www.indoaudio.com they are a ebay seller based in Cali. I am from canada so I have to pay duty and taxes on all this stuff and they helped me out with all of that plus sold me items a) I cant buy in canada b) are only sold at specialty outlets c) at incredible prices.

My new H/U is a sony specialty series which retails here for almost 400 and I paid 130 for it. Two 12" subs for 80 bucks that I cant buy here as well as matching amp for 120 that I also cant get here.

I have even called their office and theyve remembered who I am...   I dont even get that at my local stop and shop...
