It's really hard to quantify, since I never really tried to pull in distant stations, but all the local stations come in clear as ever. I think another thing to consider is that presumably the new aftermarket head units have better sensitivity and better signal processing that the early 90's factory deck, so they can get equivalent reception with less antenna.

Can anyone verify whether this Crutchfield headunit wiring harness adapter works for the 1991 MR2 with cassette player stereo?

http://www.crutchfield.com/p_1207017...e-Harness.html

The picture looks quite different compared to the Autoleads one. One poster on the Crutchfield site says it worked in the MR2 Spyder which I suspect is different than the Mk11 MR2.

That's the normal 10/6 pin harness adapter and will NOT work with a 91 with premium sound. If you have the internally amplified non-premium system it will work.

Thanks.

So this one would be for premium sound then? http://www.crutchfield.com/p_1207081...g-Harness.html


Is it safe to assume:
CD player = premium
cassette-only = non premium?

That's the adapter for '92 and later premium systems (15 pin). It won't work with the '91 14 pin system.

Basically, yes, but some non-premium systems have a single din radio and a separate single din CD player directly beneath. The premium systems had the tape & CD in one double-din unit. If there's any uncertainty check for the subwoofer(s) in the storage boxes and amps beneath the plastic panel behind the driver's seat.

Sorry to dig up an old thread OP, but do you still have the stock "mounting rings" as pictured (top) from your write-up below? If so, what is the size of original factory cutout, and does the rings have screw holes (I assume they would have to)?

Scratch that, I found this from another thread you made:

Stock trim ring hole diameter: 4-1/8"
Bolt circle of the stock speakers: 4-11/16" (4 bolts)
Door hole diameter: 5-1/8" (trim ring removed)
Trim ring/door hole bolt circle 6-3/8" (3 bolts, NOT evenly spaced)


So that leads me to my next question...Do you (or anyone else) have a pair of these you would like to sell. Chances are most people just throw these away, so I hope a set is still out there somewhere...

Has anyone managed to get rid of that godforsaken EHPS whine? I have a new/clean ground for the amp (frunk-mounted) and an unbearable whine. I'm going to try shorter/better RCA's, but I have a feeling that won't fix everything. What is everyone using for a good ground?

OP here. My plates (if I still have them) have an extra set of holes drilled in them from a previous speaker installation, so I don't think they would be useful for you.

I know how to caulk holes, lol. Seriously though, as long as the original cut-out is not altered, they would do the trick just fine. I will give you something for your trouble if you will send me the the pair.

This helped a lot as I didnt have a clue and the PO of my car didnt solder or crimp any of the connections and I always used to get static and random resets....

Thanks to the OP for all the great info. My swapped headunit sounds MUCH better, and time to setup the amp!
