Metra 82-4300

I have just installed this 1" spacer with my mb quart pvl 216 and i'm not too happy with what i'd discovered. my speakers don't fit on the inside diameter of the spacers. I had to grind 1/16 of an inch on the opening of the spacers with a dremel just to make my pvl216 fit but overall it was good just be careful with matching with your components.

Used a pair to mount Pioneer 6.5" mids from a component set-- all materials were of great quality and fit my VW Passat perfectly.
Very satisfied, will probably buy another pair for the rear doors soon.

Although claiming to be a one size fits all model, these brackets did not fit at all on my 92 accord lx. Now it could have been a lack of research on my part, but I was still upset at the end of the day.

Great adapters for giving you extra speaker clearance. Spacers were very sturdy and I liked the light wrinkle finish. Matched my tub application perfectly.

Used these on my front door components for an 01 Accord coupe. Gave me enough space for my window to roll all the way down. Had to make holes on the spacers to attach onto my door and than also had to make new holes to attach my Diamond Audio speakers to the spacers. After all that and some sheets of sound deadening material, everything worked out perfect. Very easy to install, and does what its made for.
