don't get how a 6.5 inch speaker fits to 6 inches.... can I mount a 6 inch component setup in this ?
A shopper on Dec 15, 2014
Best Answer: Hello,

Fairly substantial shaving of the bracket needs to be made to fit most 6.5" speakers. Nonetheless, that is obviously the MAXIMUM size this bracket can take, which means you would already be taking a risk by attempting it. However, a 6" woofer takes far less modification of the bracket, and is the most common use in Our install bay.

What is the cut-out diameter of this bracket? I need to mount a 6 1/2" speaker that has a 5 5/8" cut-out. Also, diameter of hole pattern on my speaker is 6 1/8". Will bracket be able to accommodate this speaker? Thanks.

Best Answer: It has been some time since I have installed this product, but I do remember having to make some modifications because I had to front mount the speaker. To be truthful, for all the cutting I had to do, if I were you, I would just get some 1/4 hardboard and make my own. Use your 6 x 9 and 6 1/2 speakers for a pattern

A shopper on Jan 3, 2015
Best Answer: Hello,

Yes, that is the bracket's intended use; To house any 6.5" woofer/speaker/coaxial . Most 6.5" drivers require a little help in getting the bracket to fit right, so be prepared to slightly modify the bracket.
