Professional Tip:
If amplifier installation kits are available with
different 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 use AWG 4 = 21 mm
2
cable for best
performance.
This is for cable lengths up to 5 meters.
The ground cable must have the same size.
