audio upgrade

[bvolin]

i am new to this forum and apologize if i am asking a question that has been previously answered. i have a 2007 bolster s with pcm 2.1 and standard (non-bose) speakers. the head unit has the newest discs but it is outdated and lacks several important features. i have bought a new pioneer avh 3300bt head unit (blue tooth, iPod, etc) and had it changed out. the installer tells me that he reused as many of the existing components as possible but the sound is poor due to "lack of cross overs/power" the new unit is driving existing door and dash speakers through original wiring and the tweeters sound very raspy. the dealer offers no advice other than "go to a professional" and the professional isn't sure of the next step. recommendations include disconnecting the existing tweeters (lowest cost), adding crossovers and/or new amplifiers.

i love my car and somewhere, someone knows the answer.

please help

Probably going to need to do as suggested. Will need to likely add an amp some crossover/filters and then put some new matched speakers in the appropriate areas of the car. You can search this site and find a host of articles/posts on this topic and likely some good suggested components.

The factory systems are integrated and designed to match the acoustics of the cars, so when you start changing pieces, it disrupts that design....Best to just come up with a new total design and build from there. Since you have the head unit replaced.....Just need the amp and speaker set up...

Good luck!
