OnlineCarStereo.com Car Audio Installation Accessories

Get the little things you need for replacing or upgrading your vehicle audio equipment by shopping 24/7 for wiring, tools, speaker baffles and much more.

Installation Accessories for Car Audio

Your system will sound even better when you’ve installed it correctly with help from OnlineCarStereo.com. Even factory audio elements require a variety of accessories for proper signal transfer and output. Additional recommended supplies will really separate a system from the muffled pack. We carry all the odds and ends you might need to replace the OEM system or upgrade to 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.

The Best Audio Installation Supplies

Listen to the amazing highs, mids and lows of modern audio with high-quality accessories. Factory integration wiring harnesses are a must for connecting the new element to your existing electronics. Use our Vehicle Fitment 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 block out this unwanted noise.

Tools & How-To’s

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