The Part That Makes the Rest Work

Wiring and Install Parts That Hold Up

Correct Gauge and Current

Proper conductor size and fusing keep voltage steady and the installation safe.

Clean Signal Path

Shielded interconnects and a solid ground are what keep engine whine and alternator noise out of your music.

Check Before You Wire

Confirm connector types, lengths and gauge against your vehicle and equipment before starting.

Do It Once

Quality terminals and protective loom prevent the rattles, shorts and re-dos that come with cheap parts.
