Description

The Gravity Audio E7500.1D Warzone mono Class D amplifier delivers powerful, controlled bass for custom car audio builds. Rated at 7,500W True RMS at 1 ohm, 4,232W at 2 ohms, and 2,400W at 4 ohms, it gives installers meaningful output options for compatible subwoofer systems. Its compact chassis, efficient MOSFET PWM power supply, integrated protection circuitry, and included remote level control are built for bass focused listening. The amplifier end panel visibly groups the main power and ground connection points with the remote turn on connection, supporting a clean, purposeful installation layout. The E7500.1D uses a MOSFET pulse width modulated power supply designed for efficient energy conversion from the vehicle electrical system. This efficient design helps make effective use of available electrical power during extended, bass intensive playback. The control side presents the amplifier input, output, adjustment controls, status indicators, and remote control connection in one accessible area. Use the system design flexibility of 1, 2, or 4 ohm stable operation to match compatible subwoofer wiring configurations, then tailor bass output to the music and listening preferences of the vehicle. The mono Class D platform is dedicated to authoritative subwoofer amplification. The included remote subwoofer level control puts bass adjustment at the driver’s seat. Its rotary knob makes it convenient to raise or lower subwoofer output for different recordings, passengers, and listening preferences without changing the main amplifier settings. Power and clip indicator lights provide a clear visual status reference on the controller, helping keep level adjustments simple during daily driving. Powerful subwoofer amplification does not have to dominate every available mounting location. The E7500.1D combines a compact mono chassis with a heat dissipation design intended to support consistent performance when playback gets bass heavy. Its low profile, finned exterior and integrated mounting tabs suit custom car audio installations where space planning matters. Choose 7,500W True RMS at 1 ohm, 4,232W at 2 ohms, or 2,400W at 4 ohms to build around compatible drivers and impedance targets. The E7500.1D Warzone is designed for listeners who want a dedicated mono amplifier at the center of a serious car subwoofer system. Its high output ratings give a system builder room to select compatible subwoofers and arrange wiring around a 1, 2, or 4 ohm load. Whether the goal is deep sustained notes, impactful kick drums, or a fuller foundation beneath everyday music, the amplifier provides the power capability needed for demanding bass applications. Daily use is about more than maximum output. The included remote subwoofer level control lets the driver adapt bass level to the recording and cabin environment from the seat. Turn the level down for a more restrained mix, or bring the subwoofer presence forward when the music calls for it. This convenient adjustment helps the system stay enjoyable across different genres and listening situations. A MOSFET pulse width modulated power supply is designed for efficient power conversion, helping the amplifier use the vehicle electrical system effectively. The compact chassis helps expand placement possibilities in custom builds, while the heat dissipation design supports consistent operation during bass intensive sessions. Integrated 4 way protection monitors high voltage, low voltage, over current, and high temperature conditions, adding an important layer of oversight as vehicle electrical conditions and listening demands change. For installers and enthusiasts building around compatible subwoofers, the E7500.1D brings together mono Class D efficiency, selectable impedance stability, substantial True RMS power, and driver accessible bass adjustment. It is a focused solution for car audio systems where strong low frequency output, installation flexibility, and practical control matter. The Gravity Audio E7500.1D Warzone is a high output mono Class D car subwoofer amplifier engineered for custom car audio systems that demand powerful, controlled bass in a compact installation footprint. It delivers 7,500W True RMS at 1 ohm, 4,232W True RMS at 2 ohms, and 2,400W True RMS at 4 ohms, allowing installers to match the amplifier with compatible subwoofer configurations and selected impedance targets. With stable operation at 1, 2, and 4 ohms, the E7500.1D offers meaningful flexibility for single and multiple subwoofer wiring plans. At the core of the amplifier is a MOSFET pulse width modulated power supply designed for efficient energy conversion from the vehicle electrical system. This design helps maximize available output while supporting extended bass heavy playback. The dedicated mono Class D architecture is built for subwoofer duty, delivering the authority needed for deep low frequency response and forceful bass impact in demanding vehicle audio applications. The E7500.1D pairs its substantial output capability with a compact mono chassis, making it practical for custom installations where mounting space is limited. Its heat dissipation design supports consistent operation during bass intensive listening, while the compact footprint can fit more installation locations than larger amplifier designs. This makes the amplifier a strong choice for system builders balancing high output goals with real world space constraints. An included remote subwoofer level control provides convenient bass adjustment from the driver’s seat. Adjust the subwoofer level to suit different music, recordings, passengers, and listening preferences without changing the main amplifier settings. For added operational oversight, integrated 4 way protection circuitry monitors high voltage, low voltage, over current, and high temperature conditions. The Gravity Audio E7500.1D Warzone brings together 7,500W True RMS capability at 1 ohm, flexible 1, 2, and 4 ohm stability, efficient MOSFET PWM power conversion, compact packaging, thermal support, and convenient remote bass control for serious car subwoofer systems.

You better have the big three done
Size: 7500W
For the price of the dollar for dollar it is amazing holy cow! This thing outperform my terramps by far I mean by far the quality of the sound is much cleaner and of course it's just as easy to install I would make the change if I was you. Remember though for those that don't know get your big three done first don't even try to hook up these big amps and then be all whiny butthurt when you smoke the thing cuz it doesn't have enough power. ... show more

Don’t buy this amp if you want power
Size: 7500W
Worse amp ever I’ve had to put it the shop multiple times, the slightest vibration from my subwoofers shakes the inside of the amp loose and it stops working on top of that I have the amp turned down to the lowest settings bc it can’t handle the power of my subwoofers it goes into protection mode even though it’s made by the same company ... show more

More power than my current subwoofers can handle!
Size: 7500W
This thing is massive not just in size but in power as well! I've never owned an amplifier this big, heavy, or with this much wattage output. I connected it to my existing system in place of an older subwoofer amp, and it will definitely blow out my current subwoofers if I try to turn up the gain too much. I am very impressed with this unit and really like that it has built in cooling fans and a subwoofer control. The bass is clean and accurate. My mind is blown by how much technology has advanced for what you are getting at this price point. With that being said, I highly recommend this amplifier with the top rating! ... show more

Big but impressive!
Size: 7500W
I knew this amp claimed to put out a lot of Watts but I was not prepared for how big it was going to be. I don't think this is an issue because if you know you need this much power, you should know it will be big. I am not driving this to its fullest and I don't think it is good for an amp to run at its max. I know it will be able to do it as it is a very nice amp. I love that it comes with the bass control knob! I haven't owned an after market amp since I was in college and they have really come a long way. Back then, you would need a named brand amp if you wanted it to work for more than a few months but now there are so many good ones on the market at better price points and this is one of them! I highly recommend and would buy it again! ... show more

Boomin' amplifier
Size: 7500W
I have a hard time being a serious adult. I own my own business and we have several trucks that we use for various things around town. I thought it would be hilarious to put a boomin' sound system in the company trucks. The guys that use the trucks thought it was a great idea. When I brought this to install in one of the trucks they knew I was serious. Not much to say about it--it was easy to install and as the product description says it 'absolutely pounds'. Highly recommended!! ... show more

So much power.
Size: 7500W
When I realized that my car's setup was woefully insufficient to test and review this amplifier, I called a friend with custom sound and asked if he was up to the task. He agreed, I stopped over and we swapped his amplifier with the Gravity amp, running it at 4 ohms. He uses a pair of 15"s in the trunk and the amplifier made his prior custom setup from the sound shop look completely amateur in the gross volume of sound and bass sound category, just a wall of sound. It scored slightly less clear in the clarity category, but in my opinion, if you're dropping a 7500-watt amplifier into a vehicle, it's entirely possible that hearing all the fine notes may not be your primary concern. The amplifier worked well, no overheating or static noted during the testing. Recommended. ... show more

Super strong power
Size: 7500W
This is my second Gravity amp, I had 5000w now I tried 7500W and I'm in love with them. First of all, so many amps advertising they have 5000 or 3000w, but so many don't give you this much power, but these guys are giving you what they described. Also, you'll receive the bass Remote as well which is not included in other brands. The only thing i didn't like about this amp is the weight and it's huge, so you'll need a little bigger space to install it. ... show more
