Hey, here's the scoop. i plan on adding a AccuGroove Gordo 18inch sub to my tri 210L now, the 2 10 handles 600 watts( 4 and 8 ohms) and the gordo i believe is 800 watts ! 8 ohms what kinda power should i be giving these things? i play a 6 string fretless F bass and a F bass 5 string fretted. i play funk, R n B, reggae, jazz, soul, rock, pop, well, pretty much everything i currently have a wt-600 amplifier, and i kinda like the sound i'm getting, but i'm sure it could be better. I think i may have to run a power amp/pre amp set up so i can have maximum head room, because right now, i know i am pumping my eden head wayy to hard, ( no lights are flashing, but it doens't get much louder) what do u guys think??
