MJM Car Speaker Adapters 6 1/2" 6.5" Rear - SAK044_55-1 Pair

This is exactly what we needed for our 91 Nissan

These adapters look good and I was impressed that they came with washers and screws. I haven't installed them on my car since I haven't bought the speakers lol. Also I noticed that one of the adapters is smaller than the other one I really don't know if is because the speaker enclosures might be a little different, i really don't know but will definitely write another review to keep you guys informed

Do not waste your time buying these. I have a DS18 6.5" speaker in which this adapter does not fit the circumference.

Worked perfectly. Thankfully the kit includes much needed washers to hold the adapter to the stock speaker box. Also in the left side I used two adapters to get spacing because that box seems to be quite a bit shallower at least on the 2 seat 300zx.I did also drilled a hole in order to pass the factory harness into the box even though I took the Bose amps out.

Service was excellent. It was exactly as described in the ad. Do like the material from which it is made. Can be trimmed if necessary. The adapters will allow me to use larger speakers in the stock Bose rear case. Provided screws with washers makes the alignment easier.
