as the ground cable, making sure you install in-line fuse holder, approximately 11 inches to 16 inches
GROUND ( GND )
Keep this cable as short as possible (not longer than 20 inches ).
Making sure that the connection with the chassis is rust free and clear of paint or grime.
REMOTE ( REM )
Connect the REM terminal of the amplifier to the power antenna terminal or the dedicated remote
turn on using 12 or 16 ga. electrical wire.
Caution
THE JP-95 is not supplied with internal fuses.
Make sure you install an in-line fuse holder

The JP95 amplifier has STATE OF THE ART protection features to prevent any damage from misuse or faulty
conditions. IF the amplifier senses excessive heat, short circuited speakers DC, or voltage, the protection
indicator will light, and the system will be turned off. In order to check the problem, you should turn all
level down and all power off and carefully check the installation for wiring mistakes or short, check the
subwoofer too sometimes spiders rip and they short the coil..
If amplifier shuts down due to excessive heat, it will work once it cools down. Check Bass Remote the Temp
efore removing your amplifier, refer the list below and follow
the suggested procedures.
NO OUTPUT
1. Check remote turn-on voltage at amplifier and headunit, when remote turn-on voltage is low or
no turn-on voltage, amplifiers will remain off.
3. Check RCA Input is properly connected.
AMPLIFIER SHUT DOWN ( PROTECTION )
1. Please check POWER, GND and REMOTE wire connection and other wires for proper connection.
2. When input voltage greater then 4V DC is present at the amplifiers RCA input, the amp will go into DC
protect. In this case, remove the RCA input cable.
Check whether the amplifier comes out of the protection. if it does, you will need to replace the headunit or
signal processing source.
3. If amplifier overheats, the thermal protection will turn off the amp. Amplifier will be back to work
4. JP-95 has minimum working impedance of 2ohm stereo or 4ohm bridged for CH1 - CH4 and 1ohm mono for CH5.
5. JP-95 working voltage is 9V - 16Volts.
6. Make sure Chassis and Remote use same GROUND.
DISTORTION & NOISE
1. Please readjust amplifier input gain level which is printed on endplate.
2. Make sure there is a good ground connection for amplifier and headunit.
3. Use sufficiently shielded RCA interconnects and good RCA routing. Avoid running RCA signal wires
near power cables.
4. Check all ground connections of all other audio equipment.
POOR RESPONSE
1. Check speaker wiring and reverse polarity.
