I ended up replacing the factory Headunit with a Double-Din radio using Metra's installation kit and a PAC module in order to retain SYNC.
Ordering the parts through Crutchfield saved me alot of money. Think they had if you order radio you get 50% off Metra Kit, and also 50% off on PAC module which is great!
Clarion CX501 Clarion CX501 CD receiver at Crutchfield.com *(Our factory radios contain the Sirius satellite tuner. Take it out and we lose our Sat radio till new tuner installed, and I dont think 6 month trial can be converted over...you might have to subscribe right off.)
The door subs are still stock, interior speakers replaced with Polk db571's running off of Alpine amp, 2 12" CVX's in sealed box running off of Rockford Fosgate amp. Everything sounds great in the car now. The work was done over at Joe's Total Auto Care in Newport News, VA off of Warwick. They did excellent job soundproofing back of car as well with dynamat and spraying blowfoam in all the nooks n crannies. Also cutting up the radio loud does not dim my lights so we must have a good stock alternator in these cars.
