I don't really want to explain how or why but if you find a GT series 5 channel amplifier(and I found plenty last night, just not the GT-50...GT-5750(sp?) came up though) then you'll be just fine. Again, if you want to understand more about power etc. then google is your friend. But I can promise you that 300watts vs. 600 watts isnt' the end of the world and only equates to ~3db increase which tests have shown is the bare minimum in perceived change of sound output.
fyi... Mono Amplifiers
That should start some head scratchingHe use to rate his huge-normous SPL amp at 15 watts. Don't forget about the "under-rated" 50watt amps of the 90's winning SPL competitions
Ever seen 150+ db's w/500watts? Well 300 watts probably wouldn't hurt the output of that setup too much either ;P
edit: 1ohm = sad face![]()
