I tend to like my sounds - a lot.

So I was just wondering if it was possible to fit an aftermarket amp to a Columbus?? If not there are other options!!

No RCA outputs, but you can code the columbus to say its connected to the OEM sound system and it will convert the speaker level outputs to line level ones which you can use to drive an amp.

I have speaker line out to RCA adapters, just don't really like using them. That's great to know.
