Customer Q&A

Crutchfield asked: Why did you buy this?
Crutchfield appears to be the only merchant carrying this item [ Nicholas  Dec 02, 2016 ]
because I want to modify my 2.5 dash speakers to fit the new 3.5 and this looks like it woud help me secure the 3.5 much better [ samuel  Apr 12, 2016 ]
It looks like it will fit my oddball situation. Needed a 1/8" spacer, needed around a 3 1/2" speaker opening. Trying to fit some 4" Kicker speakers that I bought from you into a stock 1972 Dodge Challenger dash opening. (weird size" speakers original) Will definatly HAVE to modify, but wanted to retain stock cast metal speaker grills for a factory look. These are outboard speakers. Am mounting a pair in the center of dash as well. Measured 100 times, looks doable. I have experience installing. [ Jeffro  Feb 16, 2016 ]
