Review on Speaker Adapter Spacer Rings SAK011_55 1 by Adam Boudreau

Used these to replace the crappy Infinity speakers in my 2007 Jeep Wrangler soundbar with a pair of Polk db521 speakers. Fits perfectly and the speaker mounting holes line up perfectly with the holes in the adapter ring. The only downside I found was that each of the three tabs had bits of plastic sticking out (similar to a car kit, the bit left over from wood Parts were taken out of the mold) which looked pretty ugly. A few minutes, however, the Dremel and sanding drum smoothed them all out.
