Overview

Our take on the Universal Back Strap

This metal back strap features multiple mounting holes that make it a perfect for giving extra support to the rear of an aftermarket receiver in certain vehicles. You can also bend this pliable bracket to install tweeters in factory locations, or to help with any other uses your imagination can come up with. Warranty: 30 days.

Work great for installing tweeters in places that weren't designed to accomodate them!

Features

Overview: This is a universal metal back strap that will support the back portion of an aftermarket receiver that is being installed in most vehicles, RV's, trucks, or boats. It has multiple mounting/support holes that attach to the rear support of the receiver. You can then bend the bracket as needed to attach it to any support screw found inside the cavity where the receiver is being installed.

Universal Back Strap

Written by Laura, Advisor, on 11/4/2016 10:15:00 AM
This piece was vital to installing the tweeters in my S10! It was necessary to cut holes in my door and the brackets that came with the tweeters wouldn't do the trick. However, this was no problem with these back straps. We were able to bend the back strap to fit the tweeter. Then with some screws, we secured my tweeters onto my door tightly enough that there was no danger of them coming loose and they were not compromised in any way. Pretty neat and not too complicated.

Neccessary

Written by Tara, Sales Advisor, on 11/4/2016 9:43:00 AM
This handy little add-on ended up making the installation of my tweeters a breeze. And I do not use that term lightly as I do not find any work with tools to be particularly "easy". I've definitely added these to my "necessary" list.

6 -7 inch almost always cut them in installs [ michael jonas  Jan 02, 2016 ]
Pretty long. I used all mine, but I'm guessing they're around 7in. I had to cut all of mine when using them for installing tweeters. [ Jestep  Nov 06, 2015 ]
Agree with above. Only lower frequency speakers (bass) really need the acoustic backing to push the sound forward because a good deal of the bass experience is the air movement. Tweeter frames don't rattle from the sound vibration (as there is extremely little) but will if they're not mounted snug. [ Christopher  Jun 06, 2017 ]
depends if the speaker is a free air speaker or if it has requirements for enclosure space. most tweeters don't require a specific enclosure volume. also, the high frequencies produced by tweeters shouldn't shake much, if you hear or see rattling in you specific case simply put a rubber washer in between [ michael jonas  Jan 02, 2016 ]
John M. The empty space doesn't need filling; however if you are driving on roads that are rougher than normal(off road) or driving a tractor trailer I would suggest using some rubber bushings between the washers and the strap, and the washers and the mounts for the tweeter. Hope this helps [ ROBERT W  Jul 02, 2015 ]
