Speaker Placement

Morning all. I will be getting the interior done next month on my 66 F100 CC and am thinking about speaker placement before I take it in. Radio is the RetroSound Huntington. I don't wish to cut into the doors or kickpanels and I won't be using the original dash speaker hole. I'm thinking of wedge speakers under the bucketseats and 2 in the upper rear corners of the cab (maybe 2 in the front corners also). Where do you all have speaker placement and type of speakers? The fuel tank is in the cab. Cab has already been sound/heat padded all over the interior and carpet is in. With the Hedman Headers and Flowmasters, it's a little loud, but, not deafening. I like it and so does the wife. Thanks for any ideas.

I got a second set of steel door "panels" that were already mutilated and modified the holes to fit my 6x9 speakers. I added foam baffles to keep them dry - the sound wasn't affected by them, maybe improved.I soon found that the windows hit the baffles so I added some 1" spacers. Initially, I thought I could find room for speakers under the dash but you've seen that won't work.

Thanks Eric. I have the door panels, but, I have the CC door pockets (storage compartments) in the doors now and I want to keep them. As you stated, under the dash is pretty much a no go. I'll get some advice from my interior guy of course, but, wanted to see what others did, that worked for them, to bounce off him.

Here's another option. These speakers have been installed in this truck like this for years. Original headliner, too.

Just put a dual channel single speaker in the dash. You aren't going to be able to hear that radio unless you are parked, trust me. I've got headers and flowmasters and at 60 mph I can listen to talk radio if I turn it up REAL LOUD.

Could never bear to cut my doors. There’s a set of under seat speaker boxes I am watching on eBay, they are about 3” deep, I believe. There is also a two-way from Retro Sound, whom you got your radio from, either 30 or 100 watts, that fits in the stock speaker hole. No idea as to their quality. Also. Plenty of people just build custom boxes to sit behind the seat atop the fuel tank.

At my age, I don’t need any kind of world-class system, just decent sound. I do recall, though, my now 30 year old son asking me to lower the volume in my 59, when dropping him off for highschool. That’s just not right. If it doesn’t fracture your skull and make your ears bleed, it ain’t rock and roll . . .

Thanks for the pictures Chad. Like the ones up in the headliner. That's a good option and probably would look good in the rear also..
Crop Duster and Ibuzzard, thanks for the input. I don't want the dual channel in the dash. I currently have 2 under seat speakers and getting rid of them. At highway speed, forget it, too muffled. On top of the gas tank, it would be blaring right in ours ears I would think, but might be a good option to look at. Be good when I'm crankin Ozzy or AC/DC.

Here is what I did in my '65 Custom Cab. Pics below.
I is a 300 6 cyl with single exhaust and a glass pack.
I lined the entire cab(except the higher part of the firewall that would have required removing the heater and the original firewall pad) with sound deadener, two types. I slid the sound deadener as far as I could up behind the pad. Also put it in the doors. 1st layer is Fat Mat 80 mil Rattle Trap version. I believe the 50 sq ft roll did it all, about $100. 2nd layer is Frost King Duct Insulation(Lowes or Home Depot), foam foil on one side self adhesive on the other, much cheaper. Each 15' long x 12" wide x .125" thick about $19 a roll here in Calif.

I also used the RetroSound Huntington.
Dash speaker is a RetroSound 5x7 Dual Voice Coil and it sound good. Removed the original screen material for the tweeters to clear and it fit fine under the exterior factory grille.
Rear I put two 4x10 speakers. I built some thin walled boxes to hold them. Made brackets to mount them off the upper fuel tank retaining bolts. The driver side had to be more towards the middle to clear the fuel line out of the tank. I may be losing 1, maybe 2, notches on how far the seat can go back to clear the speakers but I'm 5'8" and it's fine where it is.

It all sounds pretty good. Can hear it with the windows down at freeway speeds with it turned up a little. Hear it really well with the windows up. Not using an amp but were told by the folks at Crutchfield that that would really help wakeup the rear speakers. Use good gauge and quality speaker wire too that helps.
I'm not a music snob but have played piano and trumpet most of my life so I want it to sound decent.


Grilles for boxes were cut from some old speakers. Speaker cloth could do that job too. Boxes will be painted.

Box before it ws enclosed and the metal grille added. Also lined the inside of the box with the Frost King Duct Insulation.

Thanks for the input 65. I did look at placement of the rear speakers on top of the fuel tank last night. Speakers I have are from Custom Autosound, I had these under the bucket seats. I might take a look at mounting them on the tank with some hidden brackets. That way I might get them more spaced out behind the buckets and working around the fuel line.

As I'm still looking at speaker options and placement, has anyone installed the System 1 Speaker kit from Custom Autosound? I'm getting close to a solution on the rear speakers and was thinking about this system for the front?

Unless you get some good reviews on Custom Auto Sound I personally would not use their stuff. When we build our daughter's Mustang(18 years ago) and our oldest son's Mustang(11 years ago) I used their radios, remote CD deck and the results were disappointing and the service on their part not good. Their solution to most problems was to disconnect the battery and hope it all went away when it reset. The radio always had a ticking noise even with the car not running. At least at that time there was a reason people called them Custom Auto Crap. I replaced both of their units with Retro Sound and gave away the CAS.

Although my cab is modified, I wanted the sound system to be out of sight completely. Moving the gas tank to the rear helped, but I understand that’s not what you’re doing. In any case, I placed a hidden audio system under the pasenger seat. It has a wireless remote, FM, AM and bluetooth, so I can play my CD’s with a wireles bluetooth mp3 player. I put a stereo speaker in the original spot in the dash as suggested above. I placed 4x10 speakers in the lower rear cab corner pockets, mounted to plywood baffles and covered by luan/cloth-covered grill covers....now have 4 channel sound! The rear corners were insulated with dynamat then stuffed with fiberglass insulation. This would still work with your tank in the cab, I believe. It seemed to make sense to utilize that dead space and keep all of the sound system from protruding into the already crowded cab. I am actually surprised how good it sounds. The rear speakers don’t point to your ears, so are non-directional, therefore, I don’t think it matters much if you have the tank in the cab. If this approach interests you, I can post photos of how I did the rear baffles with a piece of 1/2” angle steel tacked to the back of the cab to help support the speakers.

I would like to see any photos you have of that install. Thanks.

My last 66 I install a set of Bose cubes (type with two speakers each) with some thin angle iron on the two outer gas tank bolts pointing up. They fit behind the seat no problem and I didn't cut or drill anything. Don't underestimate these little things they are full range and had plenty clear volume. Sorry no pics.

Thanks for the input all. Radio unit is from Retro Sound and am pleased with it. I hear you on the CAS, but am looking at just their speakers, I always prefer better quality if I can get them placed right. I'll be looking into the Bose Cubes for sure. Resonateur - I'd like the pictures if you have the time. email is: hdultra96@gmail.com Unless you wanna post them here.
Also next weekend putting in the front and rear anti-sway bars from Addco. I like this hobby, it's never done!
