  • Model: 44MAGNUM
  • SKU: 1306046891
The EHX 44 Magnum power amp is a 44 watt power amplifier that's housed in an EHX Nano pedal sized housing.  No joke!  It's as small as just about any pedal on the market (and even smaller than most) and it contains enough power to drive a 4x12" speaker cab!

Save $100 when you buy this discounted package.

You can trust Geek Squad for neat, reliable and professional subwoofer and mono car amplifier installation. Purchase your installation online and then let a Geek Squad Autotech install it – done right the first time.

Package includes 12" single-voice-coil 4-ohm subwoofer for powerful sound and 770W mono amplifier with variable low-pass subwoofer crossover that produces thunderous bass tones and Geek Squad professional installation, performed at your local Best Buy store.

Note:A materials charge of $5 per vehicle will be assessed at time of installation. Standard installation does not include any vehicle-specific parts or accessories (for example, amplifier power and signal kit, line output converter for factory stereos, etc.). For an amplifier installation, these parts typically cost $79–$199 but will vary based upon your specific vehicle and the amplifier you are having installed. Additional charges for vehicle-specific parts and any non-standard installation will be assessed upon completion of the installation. If you'd like more detailed information regarding installation on your specific vehicle, find a store with an installation center and speak directly with a Geek Squad Autotech. Your Geek Squad Autotech will provide an estimate to you prior to performing work that requires an additional charge and any additional parts. See terms and conditions for further details.
