Kenwood’s KAC-M1824BT 4-channel amplifier will pump up your car’s audio system with 45 watts RMS per channel — that’s more than twice the power of most car stereos. The super-compact KAC-M1824BT will add new clarity and impact to the basic sound system of almost any kind of vehicle on land or water, and it’ll fit in a lot of places when space is tight. The amp uses plastic plugs that protect its power and speaker connections, and features a conformal coated circuit board that keeps out moisture and salt, so the party won’t stop just because of a little wetness.

If you store all your music on your phone or other portable device, you can use the KAC-M1824BT’s wireless Bluetooth connection to play your tunes — a great feature if you don’t have room to install a receiver. The wired remote controls the volume and track selection. A USB port on the amp lets you recharge your device, so you won’t miss a beat of the fun.
