3500 Watt monoblock amplifier

The Crunch Ground Pounder GP-3500.1D delivers 3500 watts at 1 ohm, 1750 watts at 2 ohms and 875 watts at 4 ohms. It operates in mono mode only for single-subwoofer systems. This accessory targets installers who need high output from one channel.

Variable 12 dB per octave crossover

The built-in electronic crossover adjusts the frequency cutoff with a 12 dB per octave slope. It lets you match the amplifier response to the subwoofer without adding external processors. The control simplifies tuning for sealed or ported enclosures.

Check impedance and mono requirements

Verify your subwoofer presents a 1, 2 or 4 ohm load before wiring. The amplifier runs in mono only, so it cannot drive stereo speakers or multiple independent channels. Ensure your electrical system can supply the current this power level demands.

Questions about this item

How often will the variable crossover at 12 dB per octave need adjustment or service?

The electronic crossover has no moving parts and requires no periodic maintenance.

Which limit appears first when running the amplifier continuously at 3500 watts into 1 ohm?

The 1-ohm load draws maximum current, so thermal protection will engage before voltage or crossover limits.

How loud does the cooling fan get when the amp runs all day at 1750 watts into 2 ohms?

The heatsink and forced-air fan keep the chassis warm but not hot, and fan noise stays at a low background level.
