But performance in the real world is affected by the acoustics of your car or home, your choice of amplification, and your source material. What wiring do I need? This has nothing to do with bridging. Or do I need to run either two 2-channel amps (1 for the speakers, 1 bridged for the sub) or a 2-channel for the speakers and a mono for the sub? Sajag, Bridging means that two channels work together to create a single output. That is, I used the specifications of the different components to plan out how they'd connect together and perform. In this instance, the amp wants both signals on the bridged channels' inputs to be identical. This makes the setup – AFTER “strapping” – stable ONLY to a 2-ohm final load . Hi Stu. Set the crossover switch to low-pass filter (LPF) or similar on your amplifier. You could get a small 2-channel amp that normally puts out two channels of 60 watts RMS, and bridge it, so it could produce an output of 190 watts RMS, which would be perfect for driving the sub. If you are bridging this 2-channel amp to one subwoofer, you will connect one piece of speaker wire from the positive terminal of channel 1 to the speaker’s positive terminal. Without knowing precisely what amp you're referring to, we can't help you with advice. Using your amplifier’s manual is the easiest way to figure out how to bridge it. Make sure the sub is 4-ohms, so the bridged channels can handle it. Again, just like bridging a two-channel amplifier, connect these speakers wires to the amplifier by unscrewing the screw, placing the wires in between the top and bottom portions of the terminal, and then screw the screws down tightly to secure the wires. Another interesting consequence of bridging is that the amplifier damping factor is cut in half when you bridge. Theoretically, bridging an amplifier allows it to produce almost four times the amount of power as it would in an un-bridged mode. Your diagrams are a little confusing. I'm just wondering will wattage over two bridged channels or will they both run at 500w. You wire the two left speakers in parallel, positive-to-positive and negative-to-negative, to a front amp channel, the two right speakers wired the same way to the other front channel, and the sub wired to the amp's bridged rear channels. A1 company!! Generally, if you use an 8 ohm speaker, and the amplifier is a good amp for driving 4 ohm speakers, it will behave well bridging.
