Installation Accessories for Car Audio

Your system will sound great when you’ve installed it correctly. But even factory audio elements require a variety of accessories for proper signal transfer and output. Additional recommended supplies will really separate your system from the muffled pack. We carry all the odds and ends you might need to replace the OEM system or upgrade aftermarket radios, media players and speakers. Hear music the way it was meant to sound by using car audio installation accessories that are up to the task. If you’re seeking to make your system look as good as it sounds, check out our car speaker accessories such as speaker baffles and speaker adapter plates. They will give you the perfect fit and the right look.

The Best Audio Installation Supplies

Listen to the amazing highs, mids and lows of modern audio with our high-quality accessories. Factory integration wiring harnesses are a must for connecting the new element to your existing electronics. Use our Vehicle Fit Guide to find harnesses designed for your car’s make and model. If you’re installing new speakers, make sure you get the right car speaker adapter plates, spacers and speaker baffles to mount them without empty space or a sloppy fit. We have plenty of universal vehicle antennas and aftermarket radio antenna adapters for getting crisp AM/FM signals. If the engine or road noise is drowning out the music, add sound-deadening materials to enjoy quiet cruising.

Tools & How-To’s

Don’t waste your time struggling with general-use tools that can ruin your new equipment. Special car audio installation tools make the process faster and easier. Our selection of car audio tools includes radio removal tools, mounting brackets, test microphones and sound mat rollers. Need a helping hand? Our car stereo training DVDs cover topics ranging from speaker enclosure design to door panel modifications for your custom installation.
