I am looking at replacing my stock stereo with either the Alpine cda-9884 or a Blaupunkt similar in price $150-$175. The Blaupunkt has a USB interface, the Alpine does not, I don't think. I would also like to eventually replace the stock "powered" sub with the Kenwood KSC-SWI. Which head unit should I go with? Also wanted to replace stock Speakers w/ MB Quarts. I am not sure which MB Quarts to go with as I cannot find the top mount depth listed online for them. I would like to stay under $50/ pair on the speakers. Can anyone point me in the right direction for the speakers? I am not overly concerned about keeping the stock speaker grills. Sorry I am not an audiophile and will probably have to pay someone to install the set-up, any mudders interested? I am in Monument, CO.
