Ok so I put my new speakers in the VR6. wired them straight up to the head unit.
I have the original vw eurovox headunit in the car. It has a eurovox 10 disc stacker in the boot. I think the stacker is usefull and would love to keep it.

But there is a problem. The vw headunit cant power the speakers. (things are never easy). Bass...forget about it.

So. Im looking at alpine head units. Would my eurovox stacker plug into todays headunits?
I cant run an amp from my oem radio can I?
