For those interrested, I installed the side panels with the newly installed speakers over the weekend. There is plenty of clearance for the 4 inch speaker magnets and the gearbox cover. The sound from opposed speakers is not at it's best, but I'm not cutting holes in the door panels. At least on long drives I don't have to pack my portable CD player anymore.
Regards
Craig

I was able to use some small tupperware containers to make a speaker enclosure on my installation. If you have room you might try it also. This helps the sound alot. I taped them in place to try it, and had to cut out one cornor to get a little clearance, but having some kind of enclosure is better than none.IMO
 
Looks good, what diameter are those speakers??

good point, I'll give that a try when my wife isn't looking.
My heater box cable may cause some problems but I can work around this.

they are listed as 4 inch, the smallest I could find off the shelf.

Hi Craig. A little-bitty aside. Your install looks very neat. A good way to make everything just a bit more crisp would be to cover those exposed hex-headed bolts with chromed plastic covers. These pop on top the head of the bolt and are usually found where license plate frames are sold.
 
Craig, what model number are those JVC speakers and where did you get them? I discovered a crack in one of my front speakers and these would be perfect replacements.

Just my opinion but, I think that you would be happier with speakers in the rear, rather than in the doors. You will definitely hear them better and you won't screw up the door panels. Mine are at the bottom of the rear panel on either side of the fuel tank. By doing that type of install, I didn't give up any rear shelf space behind the seat. See below:

I used foam baffles from parts express (doh!) /ubbthreads/images/graemlins/crazyeyes.gif

Paul, how exposed are the backs of the speakers in the trunk area? Have you ever had anything catch back there? Your installation looks like a great alternative. Thanks, Andrew
 
The brown TR6 I had, had speakers installed in the back like Paul's, it also had the two in the kidney pads and it sounded really good.
 
An enclosure on any installation is probably the most important parts as a poor quality speaker in a proper enclosure will out perform a super high quality speaker with the back open to an endless supply of air. The speaker needs the enclosure to help it develop the proper spl's and output a broad dynamic range. The lower frequencies are obviously the hardest to produce for the speaker.

On my old TR6 I made make-shift enclosures for the kidney panels out of Tupperware containers that I secured and sealed to the speakers and panels(5.25" speakers and they actually sounded pretty good). For the rear I made some wood boxes for a pair of 6x9s that placed the speakers firing more forward than upward at an angle and mounted with velcro to the rear deck so they could be removed.

Most all speaker manufacturers will have specs for the recommended cabinet volume to deliver the best sound. Not always feasible but a good piece of info.
 
I boxed then in with some old hardboard that I had hanging around and the cover in the trunk that fits up against the tank completes the install. You never see them if all of the trim is in the trunk properly.

They really do sound great, except for the cracked one up front. Especially since I installed the new JVC CD player and actually soldered all of the connectors to the harnesses. Great project while carpeting is out of the car and nothing in your way.

My car is a '74 model and when I bought it there was no cap on the nuts, or a light bar. I have been looking for something to cover them with. I have never seen a TR6 with the light bar installed. Are these an option or do they generally get chucked? I'll have a look for those caps, thanks.
 
Paul thanks for the pics. I'll try Dave's advice first and if the sond is still wanting, I'll also install rear speakers. I have a steel plate fixed across the rear opening for race specs (fire), so I will have to remove this first if I go down that path. The piping looks good on your carpet. Mine is just the raw cut edge. I'll find the speaker info and let you know.
Regards
Craig
 
Thanks Craig. I had a local upholstery shop do the piping when I had the carpet kit installed. I didn't care for the unfinished look of the roll bar with the bolts showing, so for another $80 I had the job done correctly. I didn't want to ruin the new carpet by trying to trim and cut it myself, so that's why I went with a pro.

I was at Circuit City yesterday and they have some Polk 4 X 6 speakers that sounded pretty good on display and reasonable. They were rated to 100 watts.
These looked like a possible size to install in the rear.
I wish I had seem them earlier, I replace some bad speaker that were with the car in seperate enclosures.
Also IMO to really be able to hear the radio even with the top down one needs to install an amplifier. I place mine on the firewall on the passenger side. Wife has short legs. I got a used one from the local pawn shop. Great quality but older model. The kids have to have new shiny stuff I guess. Big help. [image]https://www.polkaudio.com/caraudio/products/db460/[/image]
CC may had a better price than this.
 
Craig,

My '74 has the light bar. However, the bulb and bulb holder are missing. I believe this little piece is unobtanium. You'll have to find a used one.

Dave
 
Moss has new light bars, with holder, less bulb. Expensive though. About $125 if I remember correctly.
