Aftermarket Headunit + Premium Alpine stereo
 

Hey guys, thanks for looking at my post! I replaced my 730n with an Kenwood DDX6902S which resulted in a pretty immediate sound improvement.

However, I noticed I've kind of lost control over EQ settings thru the Premium Alpine Stereo's stock amp. I was wondering if there was some way to control the crossover settings on the AMP or add an LOC after the amp and simply connect the stock speakers that are already there to the LOC?

Basically I'm looking to reduce the bass going to the front speakers and increase the output of the subwoofer.

Thanks again!
