Professional Tip:
If amplifier installation kits are available with diffe-
rent size of power cable, chose the most heavy
power cable to improve sound quality and to allow
more amplifiers to be installed now or later.
If possible buy AWG 5 = PL 16 mm
2
(or heavier)
cable for best performance.
High current draw
The CAT31-24 Volt is an amplifier with high power out-
put. The current draw is also high so you must make
sure that your vehicles power system (battery and
alternator) can provide all the power you need. If you
have a bad battery or alternator in can result in a poor
sound or even worse, a broken battery or alternator.
