How To Bridge An Amp To 2 Ohms. You can achieve this by using a phillips screwdriver to unscrew the terminal screws. Most 4 ch amps only want to see a min 4 ohm load but i have seen instances where a 2 ohm load ran without shutting the amp down.
I am 100% opposed to bridge mode powering, period. Wire the first sub by running a wire from the positive terminal on the amp to the positive bridge terminal on the sub. You can set the gain to less than the 250 watts x 2 its rated for.
So, If You Bridge An Amp To 4 Ohms, Each Channel Sees 2 Ohms.
Bridging an amplifier cuts the resistance load (measured in ohms) in half, because each channel of the bridged pair sees one half of the speaker load. Take one negative to one positive on each sub. I have rockfords fosgate p5002 amp, 125×2 at 4 ohms, 250×2 at 2 ohms, 500×1 at 4 ohms bridged.
Another Interesting Consequence Of Bridging Is That The Amplifier Damping Factor Is Cut In Half When You Bridge.
The answer is yes, invert two channels and your 4channel have become 2 bridged channels. For this amp the sub channel is good down to 2 ohms and same with the four channel section. Simply use the extra two channels for a second speaker.
Doing So With An Xti Is Asking Far More Of The Design Than It Is Likely Capable Of If You Expect The Amp To Have A Long Life.
I am 100% opposed to bridge mode powering, period. Therefore, each channel puts out twice as much power, and the combined output is quadruple a single channel at 4 ohms. So you're trying to say you want to bridge the front channels but still use the rear channels?
Wire The First Sub By Running A Wire From The Positive Terminal On The Amp To The Positive Bridge Terminal On The Sub.
From the speaker wires, connect the positive lead to terminal a and the negative speaker lead to terminal d. You can try to bridge the two channels to the 2 ohm load and see if the amplifier turns off. As you can see, all you have to do to bridge a 4 channel amplifier is duplicate the process of bridging a 2 channel amp.
You Won't Gain Any Power Simply By Bridging The Amp.
Wire it with each sub on a seperate bridged channel and it would work. 200 watts @ 4 ohm stereo and 400 watts @ 4 ohm mono (bridged). You could run the fronts at 2 ohm stereo and the rears at 4 ohm stereo if that's what you're asking, but bridging the front two channels into one channel = mono.
