: Not much improvement after new head unit install

12-21-2003, 12:54 PM
I recently traded my 2000 prelude with a 1997 BMW 528i and loving everything about the bimmer except its sound system, so I took my head unit in the prelude (Pioneer Premier DEHP8500mp) and put it in my 528i. This head unit sounded very very good in my prelude, provided crystal clear high ends and deep bass as if I had a subwoofer. However when it's in the 528i the sound is somewhat muffled.... and frankly I don't think it's much better than the stock unit.

Has anybody experienced the same thing? One thing that's in my mind that could cause this problem might be the amplifier from factory? Not really an audio expert so really need your input!

Thanks a lot
