Has anyone here used these brackets?

Here is a short video on them:

The idea of these brackets are to allow you to place 6.5" components in place of the factory 6x9 speakers.

I have a set of polk MM6501's siting new in box that I really want to install. However I have no place to install them. These brackets may be the answer. However I have found hardly any feedback on these so I figured I would ask around here first to see if any of you have used them before.

Any help will be appreciated...

 

I usually make adapter plates like this out of masonite, it's thin and strong, and doesn't resonate the same as the plastic adapter plates (lower resonant frequency).

 

I looked up Masonite as I had never heard of it. I may actually consider custom making them with this material. Out of curiosity, do you happen to sell pre-cut Masonite 6x9 brackets for third gens? I know I should probably just try and make them my self; but I kind of want a semi plug & play mounting set up. ("semi plug & play" as in just minor trimming needed to install.) If you do please PM me; I would be interested.

Either way thank you for bringing Masonite to my attention. I appreciate the info.

 

I bought a set of these once... sounded like crap. Tons of vibration in my particular instance. I went stupid overkill on mine... I used 3/4 plywood and mounted my speakers through the sail panels, so you can see them in the car. Yes most people would frown on this since I cut up some good sail panels, but I like people to see what I have installed. I also have a lot of blue leds in the car and plan on lighting up the speaker grills to match.

 

I usually make my own. These are 1/4" MDF if I remember correctly.

 

Thanks for the heads up! I'll go ahead and just fabricate them like 87350IROC did.

 

I'm going to set mine up similar to yours. I just need to stop procrastinating and get these brackets made already. The 6x9 Polk db's just aren't cutting it. Thanks for the pic.

 

polk dbs sound good if they are properly powered, otherwise you wont do them justice.

 

I totally agree with you. I'm pushing them on a PA660.4 Polk amp. Make no mistake, they sound really nice for a 6x9. I mean really nice. But they just don't compare to a set of 6.5" components (to my ears anyways).

 

if you have subs to fill in the bass than i would agree, this is what i have in my dd. but if you dont want the weight, subs and additional amps and big box, as in my firebird the 6x9s fill in alot more low end than the 6.5 components.

 

You can get 1/4" mdf from Home Depot in 2' x 4' sheets for less than $8

I used this in the past on all my adapter plates, just trim it out and you can spray them with some flat black paint to make them blend in
