Alright guys, I need your help. I absolutely do NOT understand this ohm stuff. I'm about to buy the Peavey 2x10 TVX with a rating of 175 watts RMS continous @ 4 ohms and 350 watts program. I am also going to buy the Peavey Firebass head with 700 watts into 2 ohms, 475 into 4 ohms, and 275 into 8 ohms. What does all of this mean? I'm also going to buy in a month the Peavey 4x10 TVX cab. Should this be an 8 ohm or a 4 ohm cab and why? Thanks guys. Again, i'm a complete idiot when it comes to this stuff.
