I have an 05 too! Went to Sound Waves in Parsippany, NJ – class operation there, had the subwoofer replaced, new head unit, new amp – very happy with results, OEM quality and warrantied.
I recently got a 2005 Gen 3 SRT10 that needs some servicing. I have it in the capable hands of Chuck Tator to get the mechanicals up to snuff. I’m looking for someone to fix the audio system (Chuck doesn’t do that). Any suggestions on a shop in/near NJ that can do a good job? Trying to avoid someone who is gonna do more harm than good…
