Powerful and Compact 415-Watt Subwoofer Amplifier

A 415-watt mono subwoofer amplifier with on-board variable electronic crossover, the GX-A3001 features a compact footprint of just 2-1/16" (52mm) high, 9-1/8" (206mm) wide and 11 7/16" (291mm) deep. This tiny powerhouse includes a cast-aluminum heat sink, built-in electronic crossover networks, and enough power to drive your woofers to distraction. With almost seven decades of experience in bringing live music to life, JBL® has adapted many of our professional technologies for use in our car audio systems, transforming your road-going listening experience with new levels of power and clarity. Whether you’re looking at dramatically improving the sound of your factory installed audio system or designing a world-class competitive sound system from the chassis up, your JBL car audio retailer has everything you’re looking for. Crank up both the volume and the fidelity of your factory-installed sound system with the new GX Series amplifiers. Ranging from a compact stereo amplifier with enough power to drive the most demanding speaker systems, to the thunderous GX-A3001 with well over 400 watts of raw bass power to shake the ground, GX amplifiers cover the range at surprisingly affordable prices. There’s nothing wrong with your existing audio system that real power can’t fix, and GX series amps make adding that power easy. Setting up a sound system to fill your car takes not only great gear, but the ability to make all the components work together as an integrated whole. On board active crossovers and separate line- and speaker-level inputs make it easy to tie the new GX amps to the rest of your system, and carefully engineered Bass Boost circuits make it easy to get the sound you crave, whether you’re upgrading a factory system or building from scratch. For years, JBL’s engineers have made the gear that experts have relied on. Now, we also make gear that helps you perform like an expert.

My sub only works on low bass, everything I turn it up the sub stops working and the green light turn's off for the red light to come on on the amp. Any reasons why it is doing this or a way to fix the problem?

Asked by: Conz
Hi. It is not so easy to troubleshoot your problem. Some possible reasons may be that power cord or ground cord are not connected properly, or there is a defect in the subwoofer drive unit itself, or the amplifier is defective. You may also have connected a subwoofer that has very low impedance, making the amp switch off to protect itself. It is best to seek help from someone who can do measurements of the system in the car.

Hi, I have a single 2-Ohm JBL MS-10SD2 shallow Sub- so should I connect the red+ to terminal 1 & the black- to terminal 2 or to terminal 4 on the A3001 Amp? Also, is it OK to bolt it upside down in the boot onto the rear shelf / deck next to the Sub?

Asked by: Pulsarlaser
Hi, A single 2 ohm's subwoofer is connected to just a single channel ( not bridged ). If you have a 2nd 2ohm subwoofer, you will need to connect them serial on the 2 channels. ( You can find this information in the owners' manual you can find on our product page ). As for where to place the amplifier, this can be done upside down, or on it's side without any issues If you require further assistance, you can always reach us by email customer.support@harman.com or of course by phone

What is proper wiring for a 2 ohm speaker so i can get the full 300 rms of the amp

Asked by: shaun35
The GX-A3001 has two parallel sets of speaker connectors, allowing you to connect two subwoofers. If you are using a single subwoofer rated at 2-ohms you can connect it to either set of GX-A3001 speaker connectors, and this will provide that subwoofer the full 300W RMS of power.

Is it good for jbl ms-10sd2 10" 1000w slim subwoofer? Subwoofer will work with maximum power or not? 

Asked by: Minde
Hí. Yes, the 3001 will be a fine amplifier for the MS-10 subwoofer. Power is fine, enough, but not too much, and not too little.
