I have a 1991 Rx7 convertible and i've noticed the stock sound system is really quiet, I can't hear anything with the windows down. So i've decided to upgrade everything. I know the door speakers are 6.5 inch and the headrest speakers are 3.5 inch. What size are the ones behind the seats close to the floor. Also the thread that sows standard equipment says it came with 8 speakers but I can only find 6 places. Another thing I want to do is change that radio to a new doube din radio. What do I need to do to put a new double din stereo in there can I use the same mounting brackets? Also how do I take the speakers close to the floor out and the ones in the headrest and the two that I cant find. Links would be very helpful, Thank You!!!!

ah! i was going to say the parts catalog only shows 4, but then if we add the headrest speakers its 8.

so two door, two behind the seats, and then 2 in each headrest

VasiliBrown

Ohhhhhhhh. I forgot to count the passenger seat. Wow

What you can fit in the little boxes behind the seats depends on the depth of the magnet on the speaker. I have Boston Pro 4" in the box.

If you put an aftermarket headunit in you won't be keeping the OEM bracket, well unless you want to try and rig something up. Most people get a mounting kit.

Some advice from a fellow vert owner with aftermarket stereo. Get a headunit which allows you to angle the faceplate. With the top down the sun hits the headunit just right and you can't see a thing on it.

honestly I dont think you need much to get better sound out of a vert. Any aftermarket head unit and modern speakers to replace the stock ones will end up doing the job. Thats how I started my vert. Basic head unit and infinity speakers where ever they would fit. At the moment I have a pioneer app radio2 (you can fit any double din stereo in our dash) mated to a jbl ms8 and same infinity speakers I started with. There is a good amount of room where where spare tire is to put a sub if you need some bass. I can't give you much detail on speaker size since I have an 88 vert. 88's use 4 inch dash and 5 1/4 doors.

I would just re-wire the whole thing.
I re-installed and re-wired a customers vert minus the head speakers.
I didn't want to risk damaging the headrest so did away with it.
The rear spare tire area can hold a decent subwoofer. Opted for a shallow mount Pioneer subwoofer at spare tire area. Rest of the speakers were replaced with Infinity and powered by Rockfords. I was shocked at the sound improvement and sat in the car blasting Rush Tom Sawyer .

It's a LOT easier to work with after removing the seats to make a clean install. Measure twice and cut.

Do you have a picture of how you mounted your sub? I have an infinity basslink crammed in the spare tire area but I am looking for something better.

^ Here's what I have Boston Pro 8 powered by a JL Slash 300/2. I've tried a JL Audio Wsomethingoranother 10 in the same spot and didn't like it.

It's a fiberglass resin and fiber molded box

I still need to know what size the speakers are near the back floorboard, how to take them out. And how to replace the headrest speakers

and justjeff mention he has 4in behind the seat.

VasiliBrown

Do you have a link for a double din mounting kit?

Driftology

Did you have to modify the sub box or cut anything in your car to fit it?

VANHALEN

I gave him 2 choices. Either remove the spare and mount it there or leave spare and mount behind pass seat.
There's no cutting ( I hate cutting to make anything fit).
Opted to mount in the spare area. I just made a sturdy bracket to hold the sub .
There's a lot of areas you can fit this thing.

The Pioneer is only 6 inches deep. It's not made for a large car but perfect for a compact or truck.
I'm planning to install one in my car as soon as I can decide on a head unit.
I didn't take pictures of it.

Or mount it in the trunk .

Once that top goes down, factor in the harmonics of the exhaust and its as if it cancels out any bass, 2 different engines and obviously 2 differnt exhausts and they both cancel out bass

spare relocated to trunk. mount cut and removed. top fits up or down. custom fiberglassed myself. beats hard.

VANHALEN

iTrader: (3)

Yes . Big difference.

VasiliBrown

How do you get to the ones behind the seats

VANHALEN

iTrader: (3)

Only way you're going to find what will fit and get an idea is look there.
If you pull the carpet back , there's space to mount speakers there.

VANHALEN

Another good unit on sale.
On our cars, you don't need a HUGE sub box with 1000watts. I think a single 10in will be more than enough for most. The key is using good amps and
making sure what ohms the subs are and wiring as such.

VasiliBrown

What do I need to install a standard double din headunit

JustJeff

What VANHALEN said, you just need to start digging to find out. Before I took those little speaker boxes out I didn't know how to get them out. I simply started taking things apart till I could get to them. IIRC the little oval speaker grill pops off of the formed carpet panel. There are probably a couple of those black plastic pins holding the formed carpet down. Pry at them with a screwdriver and they'll eventually pop out...though you may or may not break a couple in the process. I took the door sill panel off to get to the carpet panel. I pulled the carpet up a little bit at the corner of the door so that I could get a hand under the formed panel covering the speaker. Although that formed panel might just fall right off the once you take the pins off. I don't remember exactly how to do it, but it's not rocket science. Simply start taking things off till you can see what holds the little speaker box down.

Once the box is out you'll find you need to crack the box open. IIRC simply phillips head screws..or maybe little bolts. I have some spare Boston Pro 5 speakers I was hoping to squeeze in there but the box is too shallow.

I wouldn't worry too much about those little boxes though. You aren't going to get much quality sound out of them anyway. I mean they fire directly into the back of the seat and all. I have them on a little crappy Alpine V12 amp that came with the car. I've got the gains turned way down and I use them only for a little fill. If I really wanted to I could make an enclosure, then carpet it, etc. But the return on the effort simply isn't that great. That and I like keeping my interior as close to OEM as possible. Other than the tweeter pods on my mirror triangles there is no indication that I have any kind of aftermarket audio. Hell, I've even considered getting a Nakamichi headunit because they look so OEM (too bad they don't have any USB units for flash drives)

To be honest if you need to ask how for pretty basic stuff you might be better served paying someone to do it. Either that or be willing to get your hands dirty and explore with tools.

There is some truth to this, that and creating bass in a convertible is fighting a loosing battle. I'm not into those bass assault setups anyway, enjoying the full range of spectrum is a lost art in mobile fidelity :P

another place for tweeters. just used a hole saw to get them in.
