Polk Audio DXI521 with 6 X 8" Mounting Adapters

A valuable installation tool

Worked very well when putting Polk DXi 6.5s in my 98 Ford Ranger. Not very thick plastic, but that worked for me, since I didn't have much room behind the factory door panel. They are way more convenient than making your own adapter. You'll have to drill your own holes for the speaker mounts, and/or dremel them out a tad if your speakers need a larger cutout, but I used the measurements beforehand and they worked perfectly. Very nice.

Perfect

Just too easy and hard to hold when you install it

Fit Perfect, nice adapters on a budget!

These adapters are not usable for most speakers

I was trying to use these to install speakers in my 09' Ford Escape. The mounting holes are correct but the speaker cutout is not big enough. Not sure what they used to model the design but not usable for most speakers. The description says they are for 6 1/2" but hole size is undersized. I ended up making my own using 1/2" plywood at a fraction of the cost.

Time saving, great value......

I have been installing car audio for years. I would recommend this product to any amateur or expert installer. This was very easy to install and cuts time, compared to creating adapter out of ABS plastic. I have installed in several ford vehicles and was a perfect fit for the application. Thanks!

high quality product!

This product was made with quality. But unfortunately for me the units were made to thick to install in my 07' Mazda speed 3 door panels. Other than that, my shipments arrived on time and in perfect condition. Would order from again!

Clean fit.

Installed in a 2005 Ford F150 FX4 supercab.

Clean installation with the Clarion SRG1621R i bought from this website as well, with no cutting or drilling.

Good Adapter!

Was able to tap new holes in the plate for mounting a 6.5" woofer (Polk MM 6501) in the doors of my 2014 Mustang. Perfect fit to the factory mounting location.

Good

These fit my 6.5 inch coaxials in the cutout like they said. I did have to carefully drill new holes where this particular speaker needed to be mounted and it turned out well. There may be some 6.5's that won't fit in the opening, but mine did. They fit the 6x8 opening in the truck perfectly and the screw openings were right on the money.

Good speaker adapter

I use this with 5.25 inch speakers in the rear of a 1996 Ford F150. It holds the speakers in 6x8 hole very well, but just make sure you use larger screws. To completely seal the speakers, I'd recommend using Dynamat or a similar product to cover the adapter. I also used this with Pioneer 6.5s.
