Alright...I've been online amp browsing. For now I'm looking at an Ampeg SVT 4-PRO head. This is what the Ampeg site says about its power: RMS Power Output (2 ohms) : 600 x 2 RMS Power Output (4 ohms) : 490 x 2/1200 RMS Power Output (8 ohms) : 300 x 2/900 Now for cabs, that's still up in the air. With an 8x10 (4 ohms) would it be possible for me to get the 1,200 watts out of it if the head was run in bridged mono? Or would I only get 490? With a 4x10 and 15 setup (both 8 ohm cabs), I'd have to run the head at 4 ohms, correct? Now would each cab get 490 watts? Also, the SVT15E cab is rated 400 watts program...if I did run the 490 through it, nothing bad SHOULD happen correct? Thanks a lot, I'm just very confused. BTW...post 900!
