How to Bridge the Dayton SA1000 Amp

The Dayton SA1000 amplifier is capable of powering most subwoofers.

The Dayton SA1000 amplifier is commonly used among the do-it-yourself community to power passive subwoofers. The amplifier, rated at close to 500 watts at eight ohms and over 900 at four ohms, is capable of driving a wide array of subwoofer drivers. Bridging the amplifier to extract the most power possible is sometimes desired, depending on your individual audio needs.

Things You'll Need

• Speaker wire strippers
• Speaker wire banana plugs

Instructions

1. Access the back of the amplifier and locate the four clear plastic binding posts on the rear panel.

2. Strip 1/2 inch of outer insulation from the end of the speaker wires leading from the subwoofer to the amp. Twist the wire strands tightly on each conductor.

3. Unscrew the lower knurled knob at the base of the banana plug. This exposes the hole in the middle of the plug's body.

4. Slide the speaker wire into the holes on the banana plug. Match the red wire with the red stripe on the banana plug. Repeat for the black wire and black-striped banana plug.

5. Slide the red wire into the end hole of the lower set of binding posts marked with the red strip. Repeat for the black wire.

Tips & Warnings

• If you are using a 4-ohm driver, it is not recommended that you bridge the amp. Dayton specifies that the total load should be at or above four ohms at all times.
