Factory head unit and adding sub amp to it help pls!
Okay I have a 328I BMW year 2000. I want to use my factory head unit and and in a Zapco C2k 6.0 amp hooked up to a Diamond TDX 12 inch. I'll be using a subwoofer bass knob. So I was wondering what's a really Hi and low adapter, I think thats what its called. But yeah and I was wondering if I can use any other brand of subwoofer knobs? The zapco takes a phone line looking input for the subwoofer control knob and I was wondering if I can use any kind of brand for a knob thanks.
