This is a 1 channel amp and can not be bridged. It is rated at 75W X 1 channel at 4 ohms and 150W X 1 at 2 ohms.

• Hi, I can help.
• As I look at the manufacturer specs and recommendations this amp is not brigable. I figure I would tell you so you did not ruin it.
• When you bridge you turn 2 channels into 1 channel. This is already a 1 channel amp. Bridging would ruin that amp quick.

• If you have any comments please feel free to leave them here.
• Hope this helps and thank you for using FixYa.

Hello... sorry you are having a problem. If you are running the 325.1, that amplifier is strictly a mono-block amplifier (1 channel) so it is not possible to bridge it. There are 2 speaker connections on the amp but both positives and negatives are connected on the circuit board in the amp. Hope this helps. Good luck with your venture.

Good and bad news you can bridge the speaker it will make a 2 ohm load pretty hard on an amp but the Rockford can take it if you dont over drive it Bad news 400x4 will only go to 2 channels but should sound pretty good hope it helps

Here are the important concerns:
The power rating of the speaker(400W) should be 25% HIGHER than the maximum output of the amplifier BRIDGED. (Amp bridged output 200W - OK!)
The amplifier will get twice as warm running the speaker when loud.
The impedance of the speaker can be no less than 4 ohms when the amplifier is bridged. (Yes, this speaker is 4 ohms - OK!)
Your punch amp is capable of running TWO Cerwin Vega 124s, bridged.

Hello ronnieyannon,
A single 4 ohm speaker wired to each channel, like you have them wired, presents a 4 ohm load. And it appears that you have them connected properly. The 401s is only stable to 4 ohms when bridged, so if you were to parallel the 2 4 ohm subs in bridged mode, the load would be 2 ohms and the amp would most likely overheat and go into protection.

I'd wire them the way you have them wired.

Each channel of the amp outputs only 100 watts into 4 ohms. That is adequate for regular full-range speakers, component speakers, mid-range drivers, and even some small subs. But it is a little low on power for most subwoofer applications.

Hope this helps.

hey mate try putting your positive on one channel then put the negative on the other channel. So plus on 1 channel an negative on the other channel hope that helps mate if any other problems let me know [email protected] enjoy

You can't bridge this amp as it is a mono single channel amp. 2 ohms is the lowest load that can be applied for 300WRMS.
