Bridging an amplifier increases the power that can be supplied to one loudspeaker, but it does not increase the amplifiers total available power. Because a bridge amplifier operates in mono mode, a second identical amplifier is required for stereo operation. For bridged amplifiers, damping factor is cut in half.

Does bridging an amp affect sound quality?

Bridging most amplifiers will make no noticeable difference in sound quality.

Does bridging an amp make it hotter?

They run hot because each amp sees half the load and the current through the final stage doubles. Any solution is a compromise. The amp will produce the same heat with 2 ohm stereo as 4 ohm mono.

Whats better 2ohm or 4ohm?

Basically, a 2 ohm subwoofer demands less power from the amp and tends to deliver louder bass. On the contrary, a 4 ohm subwoofer will demand more power from the amp and deliver less loud but higher quality bass.

Can an amp catch fire?

Prolonged continuous operation of an amplifier, speaker, or subwoofer in a distorted, clipped or over-powered manner can cause your audio system to overheat, possibly catching fire and resulting in serious damage to your components and/or vehicle. Amplifiers require up to 4 inches (10cm) open ventilation.
