Stock amp and subwoofer only?
 

Hello,
My LT does not have the stock Subwoofer/amp... but I did buy one.

Can I use the amp to tap into the stock system just to power the Subwoofer?

Not using the amp to power the other 6 speakers, just the subwoofer.

Would I tap into the rear speakers to the to the amp?
Do I need a crossover?
Do I need Low level input converter?

I have a US8 radio with USB port. The Amp/Sub has the Connectors with a foot of wires (cut from the JY) and I have the premium wire schematic.


Thank you,
Craig~
