hey guys, i just got a Kenwood KSC-WD250 powered sub from my friend i don't have a remote for it and i just found out that it costs $100, so im just getting the wiring harness for $25. I was just wondering if i would be fine just connecting it to the head unit without getting the remote to control the bass or do I have to install the wired remote to make this sub work? or can I just use the car's head unit to control the bass?
