Car Forum / Driving, Maintenance, Tuning / Car Audio / September 2004Wiring up my single sub.
I have a 4 channel Legacy 1080a amp. If I used two channels bridged to one, what would it do to ohms that it is pushing? Would it be possible for me to bridge channel 1 and 2, then 3 and 4 and run a single sub off those two bridged channels? I don't understand all the ohm stuff really. The sub is a dual two ohm voice coil.  Signature2 - Explode Octagon 12's 1 - Legacy 1080a 500x4 bridged for subs.

Hmm, Its a Rockford Rfr3112. Its a dual 2-ohm voice coil, so it would run at dual 4 wouldn't it?

There it is, I'm having issues remembering these links.. http://www.crutchfield.com/S-8Buf5KhDjKG/cgi-bin/ProdView.asp?a=&s=0&cc=01&g=677 00&id=detailed_info&i=575RFR3112 Jason Signature2 - Explode Octagon 12's 1 - Legacy 1080a 500x4 bridged for subs.

That sub can be used as a 1 ohm, 4 ohm, or dual 2 ohm sub. you could use the sub on one half of the amp. you would do better to use a regular 2 channel amp and run one coil to each channel. > There it is, I'm having issues remembering these links.. http://www.crutchfield.com/S-8Buf5KhDjKG/cgi-bin/ProdView.asp?a=&s=0&cc=01&g=677 00&id=detailed_info&i=575RFR3112 > Jason > > Hmm, Its a Rockford Rfr3112.

The problem is I have no money for another amp at this point, so I'm not sure that I can hook this up and make it work.
