I am considering new speakers, amps and sub woofer in my 2010 SHO. I have the 12 speaker Sony system with sync. My guy said I can keep the stock radio, all I need to do is upgrade speakers and amps. My concern is rattling in the trunk, headliner, spoiler, panels, etc. from all the bass. I want either the JL audio stealth box in the trunk, or replace the factory sub in the rear deck. What, if anything, rattles with the increased bass? How much, if any, dynomat have you used? :thankyou:
