Frequently Asked Questions

What impedance should I wire my speakers to — 2-ohm or 4-ohm?

2-ohm wiring delivers maximum power (165W per channel); 4-ohm is safer for long speaker runs and reduces amplifier stress. Choose based on your speaker ohm rating and run length.

Will this fit in a saddlebag or fairing compartment?

At 15.4 in long × 11 in wide × 7.1 in tall, measure your installation space carefully. Many riders mount it under the seat or in a custom trunk.

Do I need a separate head unit, or does this integrate with my bike's existing audio?

This is a power amplifier only — it requires a preamp or head unit with RCA outputs to drive it. Most motorcycle audio systems pair this with a separate receiver or processor.

What's the weight impact on my bike?

The amplifier weighs 2.5 lbs, a negligible impact on a V-twin motorcycle's performance or handling.
