AMPLIFIERS GPV700.2 / GPV1000.2 GPV1000.4 / GPV1600.4 GPV2000.1 / GPV3000.
Ground Pounder GPV AMPLIFIERS Crunch is proud to introduce the finest high end car audio products available and would like to thank you for your continued support. The Ground Pounder Series range of products have been designed to a very high level of performance, with features unavailable in any other products.
GENERAL INSTALLATION PROCEDURE System Design The success of any car stereo system relies on several factors, such as the system design, execution of the installation, and system setup. Please remember that any system is only as good as its weakest link. Please remember that higher power systems are not necessarily useful purely for high sound pressure levels, but also to establish a headroom capability, to reproduce musical peaks cleanly without distortion.
AMPLIFIER FEATURE DESCRIPTIONS GROUND POUNDER GPV AMPLIFIERS: ! Each model is capable of 4 & 2-Ohms stereo per channel, or 4-Ohms mono bridged operation except the mono amps which are capable of 4, 2 and 1-Ohm loads. ! Tri-Mode operation with any stereo pair of amplifier channels is possible, as with all bridgeable amplifiers. ! The input sensitivities for rated output powers are variable from 0.2 volts to 5 volts on multi channel models and 0.2 volts to 6-9 volts on mono models.
GPV700.2 / GPV1000.2 2 CHANNEL AMPLIFIER APPLICATIONS FULL RANGE STEREO 1. Interconnect cable checklist: Connect the LINE INPUTS to the Radio/CD with good quality RCA cables. 2. Crossover Switch: The X-OVER switch must be in the FULL position. The MODE switch must be in the STEREO position. NOTE: Minimum final loudspeaker impedances: 4 &-2-Ohms stereo mode or 4-Ohms mono mode L + - gnd - + HI INPUT 5V 0.
GPV700.2 / GPV1000.2 2-CHANNEL AMPLIFIER APPLICATIONS Stereo high pass with mono low-pass in a 2 way active, or bi-amplified system In this application we will use a 2 channel amplifier for the high frequencies, and a second one for the low frequencies, or mono sub bass. Please consult the speaker specifications to determine maximum amplifier power requirements.
GPV1000.4 / GPV1600.4 4 CHANNEL AMPLIFIER APPLICATIONS 4 CHANNEL FULL RANGE SYSTEM Here we show how to use the 4 channel amplifiers as straight forward discrete 4 channel full range units. Interconnect cable checklist: - Connect the four inputs of the amplifier to a Radio/CD with quality RCA cables.
GPV1000.4 / GPV1600.4 4 CHANNEL AMPLIFIER APPLICATIONS 2 way active, or bi-amplified system with mono bass This application shows how easily a 2 way active system can be implemented using a 4 channel amplifier. Channels 1 and 2 will be used for highs, and channels 3 and 4 for mono bass. Interconnect cable checklist: - We need to feed the same signal to both sets of channels, so must use 2 Y-adapters, one to feed the LEFT signal to channels 1 and 3, and the right signal to channels 2 and 4, as shown.
GPV2000.1 A/B CLASS 1 CHANNEL AMPLIFIER APPLICATION Basic application These sub bass amplifiers can be used in any of the bi-amplification systems described in this manual, replacing the 2 channel amplifiers as per the illustrations. Interconnect cable checklist: Connect the inputs to a suitable source, e.g. a head unit with good quality RCA cables. Connect the LINE OUT to the inputs of the system highs amplifier. Use at least #12 gauge speaker wiring.
GPV3000.1D PRO D CLASS 1 CHANNEL AMPLIFIER APPLICATIONS Basic application FULL RANGE STEREO LINE INPUT SINGLE AMP INSTALLATION PROCEDURE: 1. Connect the amp LINE INPUTS to the Radio/CD player full range or mono line out puts with good quality RCA interconnect cables. 2. Plug in the GPR-1 bass remote module into the amp REMOTE INPUT jack. 3. Route a 0 gauge power cables directly to the vehicle battery with an in-line fuse. 4.

SETTING UP SYSTEMS AFTER INSTALLATION FOR BEST PERFORMANCE GPV700.2 / GPV1000.2 / GPV1000.4 / GPV1600.4 General: At this point you are ready to get more specific on the settings for your amplifier. High Pass: -When in Hi Pass operation, this setting acts as a low frequency cut off for your system reproduction. The point that you set it at cuts off any frequencies from reproduction beyond this point. The 12 o’clock position is a great starting point.
TROUBLESHOOTING A SYSTEM The key to finding the problem in a misbehaving sound system is to isolate parts of that system in a logical fashion to track down the fault. Description of the PROTECT system built into all GROUND POUNDER amplifiers The diagnostic system will shut down the amplifier, until reset by turning the head unit off, and back on. This state of affairs will be indicated by the front panel PROTECT LED lighting up under the following conditions: 1 - A sort circuit on the loudspeaker leads.
