Hey guy im looking for a few pointers on how to hook up my system to my stock deck the car is a 2001 volvo v40, i was just curious what that best way would be to do this.

how many amps?

im just putting one amp and one sub, i never really worked with a stock deck so im not 100% sure what to do

just use an inline converter for your rcas and run the rest like a normal install
