AMPLIFIER FUNCTIONS
1. Speaker connection
• Never connect the speaker cables with the chassis ground. This could destory your amplifier.
• Check that your speakers are connected correctly which means plus to plus and minus to minus.
We recommend speaker cable from 16 Gauge or up. Other connection ways are shown in the attach-
ment.
2. BATT+
Battery +(plus) terminal. The +(plus) 12 Volt power cable must be connected with a fuse on the bat-
tery +(plus) terminal. We recommenda fuse listed on pre-installation a 12 feet copper cable with 8
Gauge thickness or up.
3. REM
Remote terminal. The remote cable must be connected with the radio remote output
terminal so that the amplifier will switch on and off automatically with the radio. If there are two or
more amplifiers connected to this antenna terminal it might be necessary to add an additional relay.
Please consult your dealer.

ve and electric conductive place.
