I want to install a 10" subwoofer to my factory/non-Bose system(don't want to get a aftermarket HU). My question is do you guys know if 2002 non-Bose HU have a separate sub channel or do I have to get an amp? I've already installed new speakers in all four doors and want to add a little bass to the system. Thanks

 

new amp

 

Get one of the JL amps with the signal sensing function on it and you should be good to go.

 

thanks fellas
