I stumbled here as I am desperately searching to see if there is a good solution for my situation. I have a factory installed Rockford Fosgate 9 speaker system which included 4 6.5" and 4 1" tweeters and a 10" sub. I believe these are all 2ohm, and the sub is dual voice coil. This doesn't mean much to me, but what I do know is the factory amp is auto-leveling the sound output and causing a less than exciting sound experience. I do not desire to replace the speakers, or the head-unit, as I believe they will meet my needs, I just presume that the amp is the bottleneck.
My question is, how can I replace the factory amp? My reading has told me I may need line output converters, crossovers, etc. I am fine losing some integrated CAN-BUS controls (like the sub punch control, maybe even fade) but I really don't know what I need. I have found some pin diagrams for my unit so I believe I can isolate at least 4 channels of sound.
I tried to ask car audio guy at BBY if an amp swap was possible, and they made it sound like that would only work if I swapped speakers, but I dont want to go up to $400+their outrageous install prices. And then they said I would need something extra to power the sub.
I appreciate the help! Seems I may have a complex question, but I feel this must be getting more and more common the way factory stereos are being sold.
