THERES' nothing wrong with it, an amp is an amp.
BEFORE I replaced the plate amp on my sub, I used one of the spare channels
on my receiver to power my sub. WORKED fine, but you are correct in that it
is not the preferred way of doing things. A good patch in a pinch, tho.
ALSO, no reason you can't use an external amp to power a sub, just a waste of a decent amp, is all.
A PLATE AMP IS DESIGNED to drive a sub, and it just works a lot better.
