Factory system upgrades

These items include amplifiers and powered subwoofers, most of which are designed to install in an out of the way spot in your vehicle. They'll give you drastically improved sound without taking up any valuable space.

Custom subwoofer boxes

Here you'll find our full selection of custom-fit subwoofer enclosures. They have high-quality subwoofers already installed — some even have amplifiers built-in — and are all designed to fit in specific vehicles. They won't take up any valuable cargo space but will fill your car with full-bodied bass that your factory system lacks.

Sound processors for factory radios

These sound processors let you add external amplifiers to your factory radio. What makes them special is that they let you remove the pre-programmed factory sound settings and tune your audio system the way you like it, while sending a clear signal to your amps.

Vehicle-specific amps & processors and vehicle-specific amp interfaces

These items give you an easy way to replace the amp in a premium factory system. You'll get a clean signal for your amps and improved sound overall, especially if you also replace the factory speakers.
