JBL/ STADIUM4

Connectivity: You can use this amp's preamp outputs to connect to a subwoofer amp, like the matching JBL Stadium 600 or Stadium 1000, so your system will have plenty of low-end punch — a remote output connection on this amp will even turn on your sub amp. The Stadium 4 can accept low- or speaker-level inputs so it'll work in almost any system, and JBL includes RCA-to-speaker wire adapters for your convenience. They've also included their proprietary electrical anti-rotational locking (E.A.R.L.) ground terminal, for a more conductive and secure ground connection for the amplifier. 4-channel car amplifier: 100 watts RMS x 4 at 4 ohms (120 watts RMS x 4 at 2 ohms) / 240 watts RMS x 2 in bridged mode (4-ohm stable in bridged mode) Separate variable high- and low-pass filters (32-320 Hz, 12 dB/octave) on front and rear channels / Preamp inputs and outputs / Speaker-level inputs (speaker wire-to-RCA adapters included) E.A.R.L. ground terminal included / wiring and hardware not included with amplifier / 4-gauge power and ground leads recommended
