I can't help you for the interior but my father had a fiero back in the day and the custom box for my firebird fit perfectly in the "trunk" space behind the engine. I'm not too sure what it would have sounded like but I always wanted to try it.

Good Luck! I'm interested to see what you come up with.

 

Pontiac Fiero.... mmm A really good opportunity to set up a SQ system for sure! great ergonomics help PLDs!

Subscribed!

 

I have the same car. I'm planning a system based around a 10" Rockford center sub (in the console), door pods and components in the dash. It should be 11 speakers when complete. I'm designing the amp rack right now, but having trouble sourcing some of the pieces that I *think* I want/need ...

 

With a mid engine you can do 'forward' bass with a box up front and piped though the forward wall. I can only wish I had the room!

While you are at it google 'Northstar Fiero'. The 32v Caddy Northstar engines almost drop in with minor mods. No one ever laughs at 350 whp+ Fieros!

a) The Northstars are a wiring nightmare. (and I won't even talk about mechanicals!)

b) Due to the 90 degree V8 block, you need an adapter kit which adds a ton to the swap. See V8 Archie's site for that.

c) True, no one ever laughs at a 350 whp+ Fiero, but you'll never see it out of a Northstar unless you modify it. Straight out of the box, the Northstar only makes 300 at the crank in it's highest horsepower.

There are plenty of other options for engines. But I digress. The front compartment of our cars isn't that watertight. It actually has a hole in the bottom of the tire holder to allow it to drain. There is enough room to mount a sub in the floor area of the passenger side, or you can sink a pair of subs in the rear behind each seat (there's a small air gap boxed in that acts as a firewall).

 

*bumping this for new ideas*

 

Would love to see feedback and more ideas on what system I could build with the small cabin here.

Should I put speakers in the doors (not much depth possible, unless I extend it into the cabin), or keep them firing against the windshield?
(stock speaker enclosure top of dash (originally 4"x10") will fit 5.25" components.)

8" sub enclosure would fit under dash passenger side, firing downward.

Car has 4"x6" speakers in the B-pillars right by the seats. Will probably delete those. Probably no point in "rear fill" in a 2-seater.

 

Many years ago I hear a wonderful system in one of these, it had a pair of punch (original) 8'behind the seats and 5.25" components in the front. It was simple, and really accurate.

I don't think there was any rear fill but the cabin was full of sound.

I would try to keep the install simple and if it wasn't enough, add more.

Okay, let's hear your ideas..

8" JL Audio w3, or w7 under dash? W7 would probably require a larger enclosure that would use up more footwell.
Will the w7 be overkill?

I like the idea of an all-in-one amp, for space reasons. So a 5 channel, or 6 channel.

Still not sure about components.

 

Are you wanting to go active, or stay passive? Sounds like you could get some great sound with a simple two-way front stage, and then a beefy 8".

 

I'm open still. a 2-way, or 3-way was my plan. Still deciding if I want to do 6.5", or 5.25".

Also should I have the tweeters firing against the windshield? (see picture of car), or should I make a pod to aim them?

Does it matter if I aim the larger speaker? (woofer in 2-way, midrange in 3-way)

Has anyone ever attempted something like the Audi Bang & Olufsen speaker pod?

Doesn't have to move, but would be cool. Or other pods that could pop out of the dash?

 

For SQ.... with TA in your budget:

If... from your normal driving possition you can see the kick area.... I would go:

6.5 MidBass in kick area (I know you wrote: "Not a whole lot of room for kick panels as that is a foot rest, and the front tires are behind it."
but if you are planing on rebuilding the dash area you can remove the foot rest.

The interior of the Fiero gives you great PLDs to work with that will help you in your system.

Tweeters in A-pillars or depending on views maybe keep tweeters in kick area too.

a small woofer up front similar to this:

If kick area is too small you can go with a 3 way and fit MIDS 3" or 4" in the kick area and MidBass in the doors like I did.

This is my kick area fitting 3" MID:

Let me put it this way... would you like to trade cars! I rather have a Fiero than a Yaris for SQ system!






D.

 

Really? I didn't think my car was all that easy to do an SQ system in. I'll see how much room there is, but I don't think the dead pedals (foot rest) are removable.

 

Check out these 2 diagrams I made, .... look at the proportions and the speaker location in different cars.

Have you heard the expression "Singing on top of the hood" (see the stage on the Mustang)

My Yaris:

This Ford Mustang benefits from it's ergonomics for a better stage, same with a Fiero:

 

There were some systems done in Fieros back in the 1990s that I remember seeing in Car Audio & Electronics, Car Stereo Review, and such. I don't remember names or specifics, but the front trunk was almost always used for a subwoofer and the output was piped through the firewall.

 

Thought about that. Not sure if I'd be willing to give up the storage. It's already a premium on this car. I was thinking about removing the spare tire out of the front and carpeting it and having a second trunk in the front, like the Porsche Boxster. It's nice that unlike real mid-engine exotics I have a vertical trunk behind the engine. Even with it's odd shape it fits quite a bit.

 

I'm waiting on better images of a "gutted" Fiero interior, but here's some ideas:

This is likely where I'd mount a 8" downfiring subwoofer (passenger side against right fender):
Stock this location had an optional 5"-6" "subwoofer".
A Fiero forum member is working on an enclosure that maximizes the available airspace under the dash. Can't wait to see it finished.

The notch is because the stock 4"x10" speaker goes here firing against the dash. Depending on where I mount my speakers I may expand the box to use up this space as well. Just not sure if the effort will be worth that tiny bit of airspace. I hope someone on here can chime in.

Here are some other solutions people have made for this location:

 

Another option I have is to use a Ferrari 355 styled interior.

Fiero version:

I actually have a dash similar to the above collecting dust. (it's missing the vents and the door cards.) I was considering putting the tweeters where the side vents are, and maybe fabricating a small vent that goes next to the tweeters.

Gallardo inspired dash (not meant to be accurate):

This would be another option, but the builder has not finished it yet. (as you can see)
