Frequently Asked Questions - GP-1500.1 Crunch

What is the recommended power wire gauge for the GP-1500.1?
Use a sufficient gauge for the installed amplifier, typically 16-25 mm² (approximately 4-8 AWG). Ensure the +12V wire is fused.
How do I connect the remote turn-on wire?
Connect the REM terminal to the remote turn-on output of your head unit. If none, use the antenna relay wire (check that antenna retracts only when radio off). Otherwise, wire to a switched +12V source.
What is the minimum speaker impedance for the GP-1500.1?
The minimum final speaker impedance is 1 ohm. Lower loads may cause overheating and protection mode.
How do I adjust the input level (gain)?
Set INPUT LEVEL to 5V, turn head unit volume to 80-90%, then increase gain clockwise until distortion, then slightly turn back until clean.
What does the PROTECT LED mean?
The PROTECT LED indicates a fault: overload, excessive heat, or short circuit. The amplifier enters protection mode to prevent damage.
What is the subsonic filter and how to set it?
The subsonic filter removes very low frequencies below a set point (15-55Hz) to protect the subwoofer. Recommended setting is 15-40Hz depending on subwoofer.
Can I use the amplifier with a subwoofer box?
Do not mount the amplifier on a subwoofer box or vibrating parts to avoid damage to internal components.
What is the Bass Boost control range?
The Bass Boost adds up to +12dB at 45Hz. Use carefully to avoid distortion or clipping.
How do I connect multiple amplifiers?
Use the RCA Line Output (full-range) to daisy-chain additional amplifiers. This output is not affected by the lowpass filter.
What are the dimensions of the GP-1500.1?
Heatsink dimensions: width 262 mm, height 62 mm, length 560 mm. Overall dimensions may vary slightly.

General Installation Notes

The amplifier is generally mounted in the rear trunk area but can be mounted in any convenient area such as beneath a seat. Please be sure to locate this unit where you have reasonable air circulation and protection from moisture. When considering the mounting location you should minimize the length of the power and speaker leads. Minimizing both leads will yield a more reliable installation. It is also important to ensure that the heat sink fins are not against a panel or a surface, preventing air circulation. Do not install the amplifier on a subwoofer box or on vibrating parts of the vehicle, since the vibrations can cause damage to the amplifiers electrical components.

Installation of the amplifier

Mark the location for the mounting screw holes by using the amplifier as a template. Drill holes at the marked locations and firmly fasten the amplifier in place with the mounting screws supplied in the accessory kit.

Before drilling or cutting any holes, investigate the layout of your automobile thoroughly: Take care when working near the gas lines or hydraulic lines and electrical wiring.

Electrical Connection

Ground (GND)

This wire is the electrical ground and must be fastened securely to the vehicle chassis. The best method is to use a threading sheet metal screw since the threads cut into bare metal. Ensure that all paint or other insulation is remove from around the hole area, and using self tapping screw, securely affix the bare wire ends to the vehicle chassis. Use as short a piece of cable as possible - use the same gauge as was used for the +12V cable. Make sure that the connection is safe, a loose connection may result in amplifier noise and fault condition.

Remote (REM)

Many radios or other music sources have an output terminal for connection of the remote turn-on of the power amplifier. If a radio doesn't have a remote turn-on feature, then you can use the antenna relay wire, which activates the antenna motor. Please note, if the power antenna retracts when the radio is operating, then you cannot use the antenna relay wire to operate the remote turn-on.

Batterie Connection (+12V)

This wire is usually connected directly to the positive battery terminal. Ensure that the + power supply wire is fused via an assigned fuse in line with the + power supply wire. Please use a sufficient gauge for the installed amplifiers (16-25 mm 4 ). This connection must be completed using spade lug with insulating sleeve.

Fuses

The integrated amplifier fuses protect the units from short circuit and overload.

Amplifier - Features

REMOTE CONTROL The jack is for use with the enclosed remote control. Only the low pass signal will be controlled. POWER - LED It indicates amplifier has turn on signal BASS BOOST Allows you to adjust the bass boost from 0dB up to 12dB LOWPASS The lowpass filter eliminates the higher frequencies. The built in low pass filter is fully variable from 40Hz to 150Hz with a rolloff of 12dB/octave PROTECT - LED It indicates the fault operation of the amplifier. When the fault conditions (overload, excessive heat or short circuit of speaker) arise, the protection circuit is engaged to protect both the speakers and the amplifier against damage SUBSONIC The Subsonic filter sets the lower cut-off frequency and protects the Subwoofer from damage. The subsonic frequency is fully variable from 15Hz to 55Hz INPUT This allows you to match the amplifier input sensitivity to the output level of the source OUTPUT Provides a full range line level (RCA) output that allows the use of additional amplifiers INPUT LEVEL Accepts line level (RCA) inputs from 0.2 to 5 Volts

Interconnect cable checklist:

  • Connect the INPUT of the amplifier to the head unit line output with good quality RCA to RCA cables.
  • Connect the Subwoofer with the terminal block (SPEAKER OUTPUT/ - +) of the amplifier.
    •The minimum final speaker impedance must not be below 1 Ohms. Too low speaker loads result in too high heat dissipation and may cause the amplifier run into protection.
  • Please observe speaker channel and polarity as printed by the speaker terminal block. Incorrect phasing of the speakers results in total loss of bass response.

Caution

Be careful not to connect speaker (-) to the ground or vehicle chassis.

INPUT LEVEL

  • Turn the INPUT LEVEL control on the amplifier to 5V position.
  • Turn the head unit volume control to about 80 - 90% of its full setting.
  • Turn the INPUT LEVEL control clockwise until you hear some distortion.
  • Then turn back the INPUT LEVEL control slightly until you can hear clean sound.

LOWPASS

- The lowpass filter eliminates the higher frequencies. The recommended crossover frequency ranges between 60 - 100Hz, depending on the size and response of the Subwoofer.

SUBSONIC

- The Subsonic filter sets the lower cut-off frequency and protects the Subwoofer from damage. The recommended subsonic frequency ranges between 15 - 40Hz, depending on the size and response of the Subwoofer.

BASS BOOST

- The BASS BOOST - Control increases the bass level at 45 Hz max. +12dB.

Caution! Please use the Bass-Boost carefully. The additional boost may result in clipping or overload.
