I just bought/installed a Alpine CDA-9835
I have factory doors 4" and tweets 1" (Audi)
and 5 1/4 pioneers in the read deck
250/1 running a 10w3 in custom fiberglass box in trunk


I had a JVC KD-SH99 deck running before
and it sounded good nice crisp highs and tons of bass

now my systemsounds like $hit no matter waht I do I cand get rid of the mid harshness (I almost sound like AM radio)
bass in unpredictable some song are ok but others you cant even hear it

I know I dont have the greatests system but man the alpine was a step backwards
