PH5000W/ 1

SIGNAL SENSOR: This feature allows you to

eliminate the use of a remote wire to turn on your

ampliﬁer.

In AUTO mode the amp will

automatically detect an incoming signal when the

stereo is turned on. If the ampliﬁer does not

detect a signal within 20min. it will automatically

shutdown. When in REMOTE mode the ampliﬁer

relies on the remote wire to detect a signal.

FUSE RATING SHOULD BE

NO LESS THAN 120 AMPERES

DO NOT SOLDER THE TIP OF THE POWER

CABLE (+&-). IT REDUCES THE CONTACT

SURFACE BETWEEN THE CABLE AND THE

INSIDE

THE

TERMINAL.

WHEN

TIGHTENING THE SCREW, A RAW CABLE (NO

SOLDER) EXPANDS INSIDE THE TERMINAL

CREATING LARGER CONTACT SURFACE;

THUS ELIMINATING HOT JUNCTIONS.

The gain knob is not a volume control.

It is designed to match the input level

of the amp to the output level of the

source unit. Over driving -clipping- the

input stage of the amp will cause

damage to the ampliﬁer (Please refer

to table for settings).

• Test the alternator output. Factory alternator will produce 60 to 80 amperes at best. Wear and heat

will reduce the output by 40%.

• Alternator ground (-) must be reinforced, use 4-gauge cable instead of the factory 8-gauge.

• Alternator positive (+) to battery (+) must be reinforced. Use 4-gauge cables.

• Check your battery condition. Batteries degrade after a while.

• Battery (+) to ampliﬁer (+) , must be a 4-gauge cable.

• Ground ampliﬁer to chassis using 4-gauge cable, keep the cable short (maximum 2-feet).

• Use 1 farad capacitor to compensate for surges in demand.

• We recommend the use of one (1) auxiliary battery.

Two Subwoofers

For best performance, set the

crossover knob to 200Hz (max).

Set the gain to minimum, and

slowly raise the gain. In general,

an ideal gain setting ranges

between the 9 to 10 O' Clock

position
