This is a new product SKU: SSLC

An RCA remote line level controller. Works well as a bass knob or even for zone control if you have a large vehicle (like a boat, bus, motorhome, etc).

I will include one large adhesive lined heat shrink in case you want to dissasemble the housing and flush mount this bass knob (like I usually do).
Also some (4) smaller heat shrinks to put over the RCA cable connections to keep them from pulling or vibrating off after your install (without having to use tape that leaves a sticky residue for the next installer).
