Pre-wired Speaker Wiring Harness for 1x12 and 2x12 Combo Amps

Swap speakers with no soldering.
We've made it fast and easy to upgrade the speakers in your combo.

We made these pre-wired harnesses to easily upgrade your combo and speakers at the same time. Each is handmade in our Ohio shop with only top-quality components: premium 16 gauge insulated wire, Switchcraft pancake plug, and rugged quick disconnect terminal ends. They're expertly soldered for a lifetime of use.

This harness installs in your 1x12 or 2x12 combo and replaces the wires to the speakers. With the quick disconnect terminals you can now swap in a new speaker quickly and painlessly, no soldering required.

This set comes with two sets of wire, one wired directly to the pancake plug for 1x12 installations, and an additional set of jumper wires for 2x12 installations for both series and parallel wiring configurations. The wires are long enough to give you plenty of flexibility in most cabs.
