5. M Series amplifiers are designed to operate from a car s 12 volt negative ground electrical system The power and ground cables should be a minimum of 8 gauge Depending upon the complexity of your system larger gauge wire may be needed The main power cable should run from the amplifier location through the vehi cle to the battery avoiding sharp corners creases and sharp body parts When passing through any metal wall i e fire wall etc a grommet must be used to prevent the wire from chafing and shorting to ground The M Series amplifiers do not have an on board fuse An outboard fuse must be installed in line with the power wire within 12 inches of the battery Use the following fuse values at the battery 121m and 202m 30 Amp 404m 50 Amp If multiple amps are being used the fuse value should equal the com bined total demand of all amplifiers in the system A second outboard fuse may be added close to the amplifier if desired Consult your Authorized Xtant Dealer for an appropriate in line fuse holder that meets the needs of your installation We suggest crimping and soldering all wire connections Insulate the connection with heat shrink to prevent a short to ground The ground wire should be of the same gauge as the power wire As a rule of thumb use as short a length of wire as possible Locate an area near the amplifier that is metal the floor or an existing unused threaded bolt hole is ideal and clean the area to bare me
