Looking to eventually replace the factory system, non RF, in my '10 cc. I plan on keeping the factory head unit so I know i will need a sound processor to restore a "true" signal. I was looking on tech12volts.com and noticed a cdt audio package he sells. I read some reviews and the products seem to be great. Anyone have them and care to shed some light. Also if not, can you recommend a setup. I'm not sure on the difference between coaxial and regular speakers or if I should run components since we have tweeter mounting locations. I'm new at the audio thing but am pretty technically inclined. I was thinking Infinity, JL, or Boston Acoustics if not the CDT. Thanks for any help!
