The Kenwood KAC-M1814 is a 4-channel Class D amplifier rated 45W x 4 RMS at 4 ohms.
It's small enough to hide under a seat, with a conformal-coated board for marine and powersports use. Speaker-level inputs with signal-sensing turn-on let it work with a factory stereo.

Questions
Will it work with my factory stereo?
Yes. It has speaker-level inputs and turns on automatically when it senses a signal, so it can run from a factory radio.
What wiring kit do I need?
That depends on the amp's current draw (15A) and where it goes in the vehicle. We'll match the right gauge power kit and fuse when you book the install.
Do you install amplifiers?
Yes, at our Markham shop. We run the power wire to the battery with a fuse, set the gains and crossovers, and test the system before you leave.
