V DRIVE 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 V DRIVE 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 V DRIVE 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. The input sensitivities for rated output powers are variable from 0.2 volts to 6 volts. All crossovers are fully variable in their respective ranges. Crossover filters are 12dB/Octave.
DRA850.2 / DRA1150.2 / DRA4050.2 2 CHANNEL AMPLIFIER APPLICATIONS FULL RANGE STEREO This is the most basic application for the GROUND POUNDER Series 2 channel amplifiers. 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.
DRA850.2 / DRA1150.2 / DRA4050.2 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.
DRA1050.4 / DRA1450.4 / DRA2450.4 / DRA4050.4 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.
DRA1850.1D / DRA2550.1D / DRA3250.1D D-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.

SETTING UP SYSTEMS AFTER INSTALLATION FOR BEST PERFORMANCE DRA850.2 / DRA1150.2 / DRA4050.2 / DRA1050.4 / DRA1450.4 / DRA2450.4 / DRA4050.4 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 V-DRIVE 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.
