Frequently Asked Questions — Motorcycle Audio
What amp power should I run?
Plan for ~160–250 W RMS per pair with clean gains. Many 4-ch motorcycle amps deliver plenty of headroom at 4 Ω.
Do I need a DSP?
Not required, but a gentle PEQ/HPF helps you get more volume with less distortion. We’ll share starting points for your bike on request.
Are these weatherproof?
They’re weather treated for powersports use. Mount behind grills and away from direct spray whenever possible.
Will they fit my pods?
Most 6.5″ Harley pods work with minor adjustments. See the Fit Notes above for common exceptions.
