Hello everyone new to the site but have had my 06 300 (base model) for a few years now. I have upgraded my deck and installed an amp and subs in my trunk (all done with 4 gauge wiring with a 10 farad cap) im looking to upgrade my speakers and factory amp. Im also hooking up cross overs and an eq to my rear and dash and door speakers. My question is....can anyone suggest an aftermarket amp to replace the factory one in its original spot? Any thoughts would be appreciated. Thanks in advance.
