Most new Nissan vehicles come from the factory with the oversized 6.5″ speaker shown in the photo. To install a new pair of component or coaxial speakers, a set of mounting plates are required. These plates are made from four layers of ABS plastic, precision cut by routers to the size of the factory speaker mounts. The mounting holes are predrilled into the plastic. The hole for an aftermarket speaker is large enough to accommodate popular large frame 6.5″ speakers. These plates are 1 ” thick overall, and allow for the maximum mounting depth. Other sellers offer mounting plates that are 1″ thick all around, but they do not allow for use of the factory screws, and in some models the thicker mounting flanges can prevent the door panels from fitting properly. If you need a mounting diameter besides the standard 5.5″ please indicate this with your order.

As the owner of SRQ, let me thank you for taking the time to see what we have to offer. For more than a decade, I have been building some very unique vehicles for very particular clients. In the day to day operations of running a car audio shop, I noticed that a large segment of this industry went unserved. Clients looking to own a subwoofer enclosure made just for their vehicle are always out of luck in the chain stores or small shops without the ability to create them.
A few years ago I decided to start offering some of my own designs nationwide to those without the time or ability to create their own masterpieces. We build each of our enclosures one at time, giving them the same love and attention you would expect if you came to our store in person. The repetition of the designs and additional income of the brick and mortar store allow us to keep the prices low. For almost the same price you might expect to pay for a bland square box covered in itchy cheap carpet, we have something amazing just for your vehicle.
In case you haven't already picked out your gear, we also carry a wide range of audio products, all new and warrantied. Thanks again for coming in, and feel free to call me directly if you have any questions.
