Information About This Item

Refined Class FD Design Offers Extreme Efficiency and High-Quality Sound


An amplifier shouldn’t take up too much space, especially in your car. The GM-D1004 is a compact amplifier that can easily be installed behind the dashboard of your car – cables are included! Power can be taken from the console panel thanks to its protection control system, which suppresses excess current during large output. Additionally, it prevents extreme overheating of parts and maintains stable operations.

Small but Powerful
It may be small but don’t let the size fool you. The GM-D1004 is capable of delivering up to 400 Watts of maximum output and is more than comfortable providing 45 Watts of power per channel, that’s more than enough to improve the performance of your factory or aftermarket speakers.

Install Variety
Today more and more music lovers are taking their music off-road and finding ways to enjoy their music recreationally. With the GM-D1004 you can add great sound to your motorcycle, ATV, or boat where a conventional size amplifier may not fit.

Flexible Connectivity
For DIYers, the GM-D1004 amplifier is not only small and powerful but it’s easy to install. Simply connect power and ground at the radio and get more installation flexibility using hi-level or low-level inputs with a signal sensing remote turn on so you can use it in combination with a factory or aftermarket headunit.

    This amp is simply a must for those with tight spaces. It's a huge upgrade from a headunit powered system. Great value, just buy it.
