1976 Trans Am Rear Speaker Height
« on: February 05, 2021, 09:45:29 PM »
I posted this same question last weekend – just before the website crashed.  If you’ve already read this and responded to it, please excuse the repost because my question disappeared before I had a chance to check for any replies.

I’m looking to replace the rear speakers in a 1976 Trans Am.  The car came with aftermarket 4 ohm Craig speakers when I purchased it.  I want to go back to a more original configuration and look.  Besides, the radio requires 8 ohm speakers.

I read in another Trans Am Country post (that is now gone) that low profile speakers are required for proper stowage of the jack in the trunk.  The post was about a later model second generation Trans Am – 1978 I believe – but I’m assuming that it holds true for 1976 also.

I see that has 6x9 speakers that are 2 11/16” deep.  Will this work in the Trans Am and still allow for proper placement of the jack?  What is the maximum height speaker that can be used and still allow the proper clearance?

I'm not entirely sure, and I'd just have to look like you would.  The cars originally just had one speaker back there and if I remember correctly it didn't interfere with the jack at all.  It could have been a foot deep on the driver's side, I think.

I had a post, not the one you were thinking of, but showing rear speakers for a 78 and how the jack and tools installed correctly using a parcel tray cut. My speakers were low profile to suit the factory covers but for 4ohm stereo. They also allowed more clearance under them than the original speakers.

But you may have to add your jack and tools then measure clearance, I don't think I did. Likewise, regardless of what speakers you have, the large speaker insulated cover only fits on one side unless you clearance the side where the jack passes. It was designed for single rear speaker setup. There was also an earlier style jack holder bracket that was shorter but think it only moved the head away from the rear demister fan, didn't affect speakers or location.

Thanks, firebirdparts.  I had heard that some factory setups used the front speaker for the left channel and the rear speaker for the right channel (or the other way around).  If that's the case, I probably don't have anything to worry about.

Wallington, yours must have been the post that I referred to.  Too bad it's gone.  It was an excellent reference that made me aware that I had to consider the clearance problem.

The radio is currently packed away while the car is under restoration.  I thought that it had a single speaker in the front that handled both left and right channels with separate left and right speakers in the rear.  From what you two are telling me, that is not the case.  I'll have to get the radio out and take a look at how it is supposed to be properly connected.  Maybe I'm just making this harder than it really is.
