Blaupunkt Component systems

One word...........Infinity

For 150 you can get a set of CDT audios from thezeb.com, they are a good comp set.

I think the older blaupunkt stuff had more qaulity than present products.

Partsexpress.com has raw drivers, and you can make yourself a custom comp set.  They look like decent drivers and tweets.

I built a Blau-sponsored SQ demo VW bug four years ago, and I was very impressed by the overall sound of their component sets.  Very smooth and musical with near flat frequency response across the entire audible spectrum, relatively efficient (meaning you don't have to feed them massive amounts of amplifier power) and they looked pretty good, too.  But like Rob said, it is a matter of what sounds good to YOU.  Go to a shop and listen before you buy any speakers.  If you like them, buy them.  If you don't, try something else.

Look at Boston Acoustics ,JL Audio DEFINITELY ,Inifinity ,and KIcker. Only your ears can tell you what you like but all of the brands i have mentioned i think make really good products. They all have their certain characteristics so make sure you listen alot. DONT go to Best Buy or some big chain go to a car audio dealer only that you like. And I agree with Maxst on the older Blaupaunkt stuff was better. Ohh and try www.Crutchfield.com if you want to install yourself. They sell blaupaunkt but not their component sets. They tell you what fits in your vehicle ,how to install (very detailed instructions) ,and give you free instalation accessories. They even let you listen to what you buy for 30 days I think. They dont sell JL Audio or Boston though. Only car audio only places sell those brands.
