13. FUSES

For convenience most PowerBass AutoSound ampliﬁers utilize common automotive ATC type fuses. For con-

tinued protection in the event that a fuse blows, replace the fuse only with the same value. CAUTION: These

power fuses on the ampliﬁer chassis are for protecting the amp against over current situation. To protect the

vehicles electrical system, an additional fuse should be used within 18-inches of the battery on the 12V+

cable.

14. BATT+ (Power Input Terminal)

This terminal is the main power input for the ampliﬁer and must be connected directly to the positive (+) termi-

nal of the car battery. (see Power Cable Selection Chart for recommended wire gauge for each model).

15. REM (Remote Input Terminal)

All PowerBass AutoSound ampliﬁers can be turned on by applying 12 volts to this terminal. This can be found

on the rear of the source unit in the form of an electric antenna output, or a remote output. If this is not avail-

able you can wire to the ACC position on the key. An 18 gauge wire is sufﬁcient to run the REMOTE.

16. GND (Ground Input Terminal)

A good quality ground is required for your PowerBass AutoSound D Class ampliﬁer to operate at peak per-

formance. A short length of cable the same gauge as your power cable should be used to attach the ground

terminal directly to the chassis of the vehicle. Make sure that all of the paint is sanded or scraped away to

ensure a quality ground connection
