5 Ch. Class D System Amplifier, 900 W
JL Audio HD900/5
5-Channel Class D System Amplifier, 100 W x 4 + 500 W x 1
Thanks to its ability to act as a "one-box solution", the HD900/5 is ideal for installations where space is at a premium and sound quality is the paramount goal.
While extremely compact, this amazing amplifier will comfortably drive a complete high-performance car audio system: that is, four satellite speaker systems and a subwoofer system... with a very serious 900 watts of power!
This amplifier features a brushed aluminum finish with black powder-coated cast alloy heat sinks and bottom panel. A black powder-coated, gasketed cover is also provided to protect the controls.
