GP Car Audio
A car audio build is more than the amplifier and speakers. GP Car Audio brings installation materials and enclosure choices into the same conversation, helping you plan the parts around the system rather than treating them as an afterthought.
Explore our GP selection, including Merica OFHC cable, STFU v2 sound deadener, door-pod enclosures and Tru Spec products.
Built around car audio projects
GP Car Audio describes its start in the car audio community in 2014. Its catalog includes installation supplies alongside audio equipment and enclosure products. At 12 Volt Outlet, this page focuses on the GP products represented in our own catalog, not every item sold by the manufacturer.
The useful starting point is the job each part needs to do. Cable belongs in the electrical plan. Deadening belongs in the panel-treatment plan. An enclosure belongs in the subwoofer and space plan. Compare those jobs separately before putting the order together.
Merica OFHC power cable
Our GP Merica cable listings include 4 AWG, 1/0 AWG and 2/0 AWG choices. GP identifies its OFHC cable as oxygen-free, high-conductivity copper. Choose the exact size and offered option from the listing rather than assuming all cable is interchangeable.
Before ordering, establish the required run length and the installation requirements with your installer. Check the selected option, supplied length and connection hardware against that plan.

GP STFU v2 250 mil sound deadener combines butyl, a foil barrier and a closed-cell foam layer. The listed package options cover different areas, so compare the square footage you are buying rather than the image’s sheet stack.
Plan the treatment area and review the product’s installation information before cutting or applying material. Deadening is not a substitute for choosing the right enclosure or completing the electrical installation.

The GP selection also includes dual 8-inch flush-mount Stack Fab door-pod enclosures. These are installation components, not a promise that every door panel or every 8-inch speaker will fit. Review the specific pod dimensions, speaker requirements and fabrication work for the vehicle.
Tru Spec enclosure listings identify the intended subwoofer application and enclosure specifications. Our imported boxes are empty enclosures, not loaded subwoofer packages. Match the exact listing to the intended driver and available space, including the enclosure’s orientation.

GP Car Audio questions
Does the product photo show the quantity I will receive?
Not necessarily. Check the selected option and package description. A cable photo or stack of deadening sheets should not replace the stated length or coverage.
Are subwoofers included with the Tru Spec boxes?
The Tru Spec enclosures in this selection are empty. A compatible subwoofer model in the title describes the intended application, not an included driver.
Is the whole manufacturer catalog offered here?
No. The full-catalog button shows GP products listed at 12 Volt Outlet. Our selection is separate from the manufacturer’s broader catalog.
What should I have ready when asking for help?
For cable, have your proposed run length and equipment details. For an enclosure or pod, have the exact speaker model, vehicle information and measured installation space.
