Speaker Installation & Accessories Information

A lot of details go into getting the best performance from new car speakers during and after installation. After you choose the perfect set of speakers for the size of your car and your tastes, you still need the right car speaker accessories to compliment your new equipment, along with skilled installation.

To help you get your car audio system bumping, we offer a range of car speaker accessories and the most important parts of car speaker installation kits. Because every connection and part running from your amp to your speakers can have a dramatic effect on the quality of sound and on the life of the speakers, we carry top of the line speaker wire and car speaker connectors. These small bits of hardware are often the weakest link in a personís stereo system, and have a high impact-to-cost ratio on the quality of sound it produces.

We also feature a variety of bass blockers so that if your amp and mid-range speakers or tweeters are not perfectly compatible, you can easily cut out low-frequency sounds to protect your car speakers and get better performance from them. This will increase speaker life and improve sound quality, as well as enable you to play your stereo louder without damaging the speakers.

When it comes to installing your speakers, one of the most important goals is eliminating detrimental sound interactions that can degrade sound quality. Our range of car speaker enclosures should make it possible for you to find the right fit to install your aftermarket speakers, and are designed to accommodate various speaker baffles, which protect the actual speakers from moisture and damage, and prevent sound wave resonance and canceling from the speaker and speaker housing.

Combined with sound dampening mats, speaker spacers and installation rings, and speaker adapter brackets, these tools should make getting the most secure fit for your car speakers and subs easy, and promote sound quality as you drive.
