a la Mackie, Crown, Behringer, etc. Some have louder fans than others, but those can be swapped on the cheap.
i doubt your 363 has preouts. and i know it does not have a worthy amp section for loud stuff.
you need a pro amp I believe.
I'm a college kid that is taking the families receiver from home and i want to use it at school.
I don't know much about speakers and sound systems but someone told me that's its possible to set up a 5.1 receiver to only 2 speakers. Now it's not nearly loud enough
The receiver i have is a yamaha RX-V363
Speakers I haven't gotten yet but i was thinking something like SDAT
