I have a 2005 Tacoma with factory radio A51810. Found out that it doesn't have RCA for adding a subwoofer. Is there an adapter or a way to splice that end into the factory radio? If I get a new radio I'll have to do a lot of extra wiring because I'll need an adapter for the steering wheel controls. Gets expensive and tedious.

I'll update if it works
