NEVER operate the amplifier without the proper power and ground wire, 10 gauge minimum. NEVER operate the amplifier without proper fusing. Fuse holder must be located with in 0.5 meters from the battery. This fuse is to protect the car not the electronics. In case of a short, the fuse will blow instead of the wire burning up.
INSTALLATION MOUNTING: 1. After reading precaution, decide where you are going to install the unit. Also, see Fig.1. 2. Once the location has been determined, place the amplifier into position. Using a felt tip pen or pencil mark the four holes to be drilled for mounting. NEVER use the amplifier as a template for drilling.
CONNECTIONS INPUT CONNECTIONS This amplifier will accept low level inputs only. Low level is the same as line level. The low level signal is carried through RCA cables. It is preferred to use low level inputs to the amplifier if the head unit is equipped with the low level outputs. If not, you can use a "high to low converter"...

SPEAKER CONNECTIONS This amplifier can operate in one, two or three channel mode. The minimum impedance for single channel (bridged/mono) operation is 4 or 8 ohms. Tri channel power is referred to stereo and mono at the same time. Minimum impedance remains the same for three channel (front /subwoofer) systems as long as proper passive crossovers are used.

SPEAKER CONNECTIONS 1 CHANNEL SPEAKER WIRING DIAGRAM (PHD 11000) The Class "D" amplifier is a SINGLE CHANNEL dedicated subwoofer amplifier. Unlike other amplifiers, the Class "D" operates as a single channel and cannot be bridged. Don't be fooled by the outputs. Two outputs are used strictly for convenience and are paralleled internally on the amplifier.
SPEAKER CONNECTIONS WIRING SUBWOOFERS (DUAL AMPS) When using dual amplifiers to power one subwoofer, the Positive terminal of the Subwoofers voice coil is connected the positive terminal of the MASTER Amplifier and the Negative terminal of the Subwoofers voice coil is connected to Positive terminal on the SLAVE Amplifier. This procedure will allow the total power of both amplifiers to be added together and act like a single powerful amplifier.
5.The "BASS" function can be selected to increase low frequency response output, or decrease frequency response output. The "BASS" function will be working at only "OFF" or "L.P.F" position. The BASS is adjustable from 0 ~ 12dB boost at 50Hz. FRONT PANEL PHD2050, PHD2200 LINE LINE INPUT OUTPUT...

TROUBLE SHOOTING GUIDE. This section provides you with a catalog of amplifier symptoms and their probable causes and solutions. Before you consult this listing, make sure the vehicle's electrical system is working properly by verifying that other electrical items (e. g. headlights, windows, etc.) Still function correctly.
