Abigail W. ★★★★★

The Y-harness design made connecting my Impulse amp much cleaner than the usual rats nest of wires, and the fit in my Mini was spot-on. Really pleased with how solid the connections feel.

Harper ★★★★★

Took a chance on this harness since my Mini didn't come with a factory amp, and the plug-and-play fit was spot on. The Y-ISO design meant zero wire splicing, which saved me a whole afternoon of headaches.

Nicholas ★★★★☆

The included T-harness made connecting my Impulse 4.320 nearly plug-and-play, though I wish the wire labeling was a bit clearer for the power leads. Fit was snug but secure in my Mini.
