Hey, I have an ampeg ba210v2. It’s rated for 450 watts at 4 ohms, and 283 watts at 8 ohms. This combo needs an 8 ohm external cab to get to 4 ohms. My question is instead of adding an external cab, could I just replace the 2 stock 16 ohm speakers with new 8 ohm speakers and get 450 watts from the combo only without an extension cab. As I understand it the external cab jack on the back of the combo is wired in parallel with the interna speakers so this should be possible. However I’d like some insight before I possibly destroy my amp. Thanks in advance.
