After reading yet another post about Infinity Speakers, and the low cost, big improvement they provide for a stock system… I followed airframer84’s lead and purchased 3032cfx 3.5” for the dash, and a pair of 9633ix 6x9” for the rear deck.

Found two terrific threads, one on the BA systems and another with details about accessing the rear deck.

The dash speakers are a simple swap, but being a bit OCD… the BA speakers sockets were swapped onto the Infinity's so the harness wouldn’t need to be cut. Pics attached.

The BA socket/connectors slips/clicks onto a tab of the speaker frame. On all three units, the slot had to break. The locking detent couldn’t be unlatched and so forcing it downward/out (gently) broke it free. Simple enough to cleaned up the backside with snips and a file. Tin the tabs… a little bending, fitting, and voila.

The rear deck speakers will be a while yet. Some Kilmat has only just arrived, and some Second Skin mass loaded vinyl is to be installed while it’s pulled apart. Not likely to be a significant gain, but so long as it's apart, some sound deadening seems appropriate.

to be continued...

Rear deck access is surpisingly simple, just remove the bolster on one side and pop out the trim holder in the center. It will slide out.

Watch the spring clip at the top of the bolster, i broke mine off. Once you undo the bolt holding the bolster, slide something down from the top to compress the clip rather than just yoinking it out like a caveman. Its not hard to reattach if you snap it off though.

"Rear deck access is surpisingly simple... Watch the spring clip at the top of the bolster"

As you said, surprisingly simple! Followed the link in my previous post to see it all, but it was more than was needed. All good though, and next time will be a snap. The spring clips were easy once the flat bar came out...lol There's a loose rivet on one side from a previous removal.... can see how it would be easy to snap one off.

The rear speakers are in! Just as with the dash speakers, the oem female connectors were switched onto the new speakers. The difference is remarkable, particularly given the relatively low cost. The REF-9633IX 6x9 3-Way's have a 'boost' button in the center, in between the two little speakers. Not a power boost, but likely just side stepping a L-pad in the cross over. In any event, so bright as the speakers are to begin with... there was no need, and it's mentioned just so if anyone gets a pair... be aware, and listen for a while with each setting.

Checking polarity: It's good practice to check polarity when changing speakers. The BA speakers had no markings, and so out came a nine volt battery and clipped jumpers... mark the connector +/-, and oriented it onto the new speakers. Remember to only flash the positive lead when using a battery. You don't want to hard connect... you're just looking to see that the speaker moves out, and not in.
