assuming you have the visonik v600hc (should be the one your talking about) you could just parallel the coils in the brahma to make the sub 1 ohm, then bridge the amp to get 1000w at 1 ohm
the site is correct in a sense, its the load on the amp that determines the ohm. ohm is basically your impedance, or resistance to electrical flow on the circuit. the less ohms, the less impedance, thus more flow.
for example, this amp runs:
2 x 150W Rms @ 4 Ohm Stereo
2 x 275W Rms @ 2 Ohm Stereo
2 x 400W Rms @ 1 Ohm Stereo
2 x 500W Rms @ ½ Ohm Stereo
1 x 1000W Rms @ 1 Ohm Bridged
as you can see, the wattage increases as the ohm drops. now, to hook it up. the pic is bad (my drawrin is terrible with a mouse

) but you connect a wire from the + of one channel and the - of the other. this bridges the amp. now,to make the sub parallel, you must run the +/- wire that you just hooked up and and put the + on one terminal, and the - on the other. now, on the other side of the sub, youll see another set of terminals. get another wire, and run the + to both + terminals, then the same with the - wire. this is shown with the light blue lines. slap this baby in a box, and your all set //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
ps-it doesnt matter which side you run the wire to the amp, it can be either. just make sure the brahma bull is upright, and then whichever terminal is closest to the wall.
Hope that helps //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
