hi all, i'm having a rockford-fosgate p400-4 installed with boston acoustic sl65 in the front doors, leaving the oem speakers in the rear, but amping them. is this a fairly straight forward install for a qualified shop, using line connectors to amp the speakers? car is a 2010 wrx base. tia.

Yes it is fairly simple using a line convertor. Although make sure your fade is set more towards the front as your factory rear speakers cannot handle the same power as your aftermarket fronts.

I'm not sure what HU you have in your '10 but the premium one for the '09s is absolute trash. Better to just get rid of the stock HU and get a quality input to that amp. Just my $0.02
