Wrong section admittedly but i thought i may get an answer sooner here
Ive wired my sub and amp up in my car and my headunit has only got a green subwoofer out no preouts as such.ive bought a y splitter and plugged them both in and it doesnt work.
Before anyone asks i did wire it up outside the car and i got it working but i cant remember how i did it lol
Any advice
