[QUOTE="RobGMN, post: 8814946, member: 683408"] My advice was based on you having the same model subs, which you do not. Forget about trying to solve the imbalance by bridging. The only way you're going to get the same impedance load of 4 ohms at each channel is by a hybrid wiring scheme of running the 2 Ohm sub as series, and then paralleling that with one v.c. of the 4 ohm sub to get 2 ohms. You run that to the "left" channel on the amp, then run the other v.c. at 4 ohms to the "right" channel. The problem is they will both see the same impedance, but a very different actual load on each channel. Might work, might sound like ****. If you want to experiment, I can show you the diagram. The other options are to parallel one v.c. from each sub with the other as I think was previously described. It will drop the impedance very low, but not a problem at moderate volumes. Crank it up, and you could toast the amp. OR Run one voice coil from each sub in series with the other. You'll get 6 ohms impedance. This will reduce you power output a bit, but you'll run less risk of toasting your amp. ETA - None of these options are ideal b/c of the mismatch in models of subs. [/QUOTE]
