2002 Malibu LS Head Unit

I just got an Alpine head unit (CDA-9827) and had it installed at circuit city. The speakers don't sound as good as they used to when the stock unit was in. I don't know if its a difference in output and I don't know much about this stuff. Thanx for the help.

I dont see much of a question... You might have to just go throught he settings and tune it.... There might be like bass trebble fade and then if its advanced sometimes filters for different frequencies....So just check it out see if theres different settings like Rock Pop Powerfull or w/e good luck....For me mine was opposite new deck gave me better sound.

Yea I've played around with all the settings but it just doesn't sound like it used to, because i think the '02 ls started coming with pretty good rear speakers. I think the problem is that the alpine unit isn't putting enough power to the back speakers all the time. Thanks tho.
