Hey guys, girls in the 77 Corvette where would be the best place to put a 12 inch subwoofer? I was thinking behind the seat passenger seat or may be in the middle of my six by nines in the back. What do you people think thanks.

Put a small sub behind the passenger seat. Believe it’s an 8 in. From retro sound. Nothing crazy, just enough to bring out the bass just a little.

I built a custom speaker box and installed a 10" sub mounted behind the seat. I had T-Top mounting brackets on my luggage rack as there was no room for them anymore behind the seat.

I have two 8” JL Audio subs in a box behind the seats. Your T-tops can fit on top if you have the storage bags for them.

I got a pre-fabbed box and it has, I believe, two affordable 8" subs in it, and an affordable amp. Not sure how much volume you'd need for a 12. Speaker technology has changed since my mini truck days in the 80s when I had a Rockford Fosgate amp and two Punch 12s. I was surprised how hard those two 8s hit. And my T Tops will still fit back there. If you are interested, I'll try to find out where I got the box and what components I have.

Myself, I am thinking two powered under each seat. There are some reasonably sized that look like they would fit. Hoping somebody will chime in on how that worked for them.

Under seat is not enough for the sub but can be used for signal processing and amps.



I put amplified sub in base of the storage compartment



Not earth shattering but rounds out sound nicely.

Crutchfield shows 13 compact subwoofers. Summaries identify some of them as "fits under most car seats". At least 3 come in at 14" X 10" X 3". That's for an 8" woofer.

The floor has an indentation but I don't know its dimensions and I don't have an overall picture. These are a bit too pricey for Christmas and I will have to pull a seat to scope this out.

I did the same thing. I don't even have a radio in the C3. Why would I need one to compete with the sweet V8 music? My whisper quiet Mustang has a great sound system. Unless the C3 is somehow your ONLY car, why not specialize in the things these cars are good for?

That said, there have been some clever subwoofer enclosure builds based around the rear jack compartment. If you don't have a spare tire, you don't need a jack.

Here are a few links to get you started.

Thanks for all the ideas. I had another idea. Has anyone ever tried to cut a hole behind the passenger seat. I’m thinking about going with a 12 inch sub. I know it would be a permanent cut but then I can put whatever size sub I want. Has anyone ever done that. Thanks again for your inputs

I certainly considered cutting a hole in the rear seat bullhead into the storage boxes.

The idea was to build a sub box with a port that passed through the hole.

In the end i went with the integrated sub in storage as there is just so much other noise when on the road that it was probably not worth the effort.

Still sounds good but is not huge bass.

Because you have to crank Credence once in a while to make them feel young again.

Then you'll need to find a place to mount this. If you just use the switch, it should fit between the power window switches of 77-82 cars without power mirrors. Or replace the defroster switch.

My son is going to build a monster system. He’s thinking about this. It’s only 500 watts RMS. We should be able to hear it. It will be kind of far away, about eight inches from our ears.

Product highlights:

  • sealed truck-style enclosure
  • houses one square L7T Series dual 4-ohm voice coil 10" shallow-mount subwoofer
  • 3/4" medium-density fiberboard construction covered with carpet
  • 2-ohm impedance
  • power handling: 500 watts RMS (1000 watts peak power)
  • frequency response: 25-100 Hz
  • sensitivity: 85.98 dB
  • dimensions: 20-1/4"W x 12"H x 7-1/4"D1 x 4-3/8"D2
I mocked up a cardboard box and it just fits. There won’t be a square inch of space in the back after the amps and speakers but it will blare the metal and rattle your head.

I like it. Not sure how popular it would be on this site.
