      This is how the Infinity components fit into the 4"x10" dash opening. 5.25" woofer and 1" tweeter
Woofers with BIG magnets can cause clearance problems with the HVAC duct on the driver's side.
It may be necessary to heat the duct with a heat gun and bend it in slightly.



This is how the Infinity components fit into the 4"x10" dash opening. 5.25" woofer and 1" tweeter on a speaker plate made from 3/16" hardboard.

I've done up a template that can be used to cut out dash plates. The hardboard can be pretty fragile, especially around the 5.25" cutout, so alternative materials such as 1/4" ABS plastic could be used.



The file is in MS Word format and will print in proper scale on regular letter size paper.

Let us know how this works out for you...

      I want to do this but im a little incompetent on audio so how would you hook both of these speakers up on one channel? Thanks for the template.

Any component set will come with a passive crossover - 2 wires in, 4 wires out.
2 to the woofer, 2 to the tweeter. This is the Infinity KAPPA 50.7CS set I installed.



The woofer has a Neodymium magnet and heatsink. Very compact.

      Sitting around reading links and I decided to print out your template, I gotta say the time you put into this shows in the quality.

Very impressive, +4U.

Thanks. Cut one out of cardboard first. It gives you a good idea of how it fits in the dash. Have fun!

      How does this sound compared to a quality 4x10 coaxial?
Also, how does a good 4x6 plate compare to a 4x6 coaxial?

thanks.

I had the same question. How do they compare to having Sony Xplod's (don't like the brand for speakers) or Pioneer 4"x10"? Or 4"x6"?

I'm assuming 2-way is needed to have a decent range and sound quality from the speakers.. Right?

      Will a 6" or a 6 x 9 fit under this area in the dash with adapter plate holding it to the bottome of the dash ?

I installed a set on Eclipse 4"x10" tri-axials first. Sounded pretty, good, but these Infinity's blow them out of the water. In general, a quality set of components will produce better, more accurate sound than a co-axial. A round woofer can play louder than an oval speaker with less distortion. Install components for the front and 4"x6" plates for the rear.

The 4"x6" plates will also fit better in the pillar because the space is quite shallow and larger magnets on a co-axial don't always fit (too deep). The space is deeper in the lower section of the pillar behind the speakers. Because the plate mounts the woofer off to one side, mounting the speaker in the pillar with the woofer in the lower side of the opening usually fits.

      Thanks for the template..nice job!

I did this a few years ago with a set of 4" Kappa components. At the time I had access to a laser cutter/engraver so I cut mine out of 1/8" plexiglas and did some decoration with paint and the laser:



You can probably find someone nearby that has one of these lasers that would cut out a pair for you for a reasonable price, especially nice if you compete in any stereo competitions.

~edit~ to add a shot of the 4x6 plates referred to in the thread:

There's no password attached to the file. Download from the link by "Right-Click - Save As" to save to your machine. After it's saved, opening it should bring in on screen in MicroSoft Word. Do you have MS Word protected?

Big magnets on those speakers?? Likely hitting the HVAC duct on the back of the dash.

      Fierosound this may have been asked before but what do you recommend for subs and speakers? im assuming you would recommend the Infinity KAPPA 50.7CS for the speakers...but what about subs? you've read some of my posts and I'm looking for good...for lack of a better word...'' bump '' I want quality base that still punches. I'm beginning to think my 12" comp subs should and would be better used in a different car.

I have 10" Oz Audio subs - not longer available. And since I'm not "in the industry" I have no first hand knowledge on direct comparisons. The industry really screws things up too with over-inflated numbers because it "sounds like MORE" to the uninformed person (using PMP "Peak Music Power" (what it will take/make before it blows up) watts instead of RMS watts). Ignore the BIG numbers, and use the RMS watts ratings whenever matching speakers/subs to amplifier power.

But general guidelines:

- in a Fiero, two 10" subs are plenty AND easier to fit and have a wide selection.
- you DO NOT need 1000 watt subs (likely a PMP rating anyway). 100-250 RMS watts per sub is plenty provided your amp puts out 250 RMS watts per channel. (300 RMS amp to a 250 RMS sub is OK)
- To me - efficiency rating is more important (rating is deciBels per 1 Watt measured from 1 meter away). 89 dB/W/m is more efficient (and louder) than 83 dB/W/m at 1 Watt.

See what the guys in the Subwoofer forum are talking about. Search forum using "small enclosure": http://www.caraudioforum.com/

I just printed and cut the plates but also didn't work with the Boston S50 I used. I guess the magnet and depth of those Infinity gotta be very small. At the end I had to move the speakers toward the center. The template is good but don't cut the speaker holes until you measure several times.

Yup - BIG magnets may cause a problem. The Infinity 50.7CS I used have a Neodymium magnet and heatsink. Very compact. Some on eBay.

      I was just wondering. If the Fiero sound system was to be redesigned, from scratch. How would one go about doing it? Is there a better speaker placement then the dash? Should speakers be placed in the doors or the foot wells? How about tweeters in the A-pillars?

I'm just rambling! But I would like a better sound stage and I am redesigning the interior of my Fiero. So now would be a good time to figure out speaker placement.

On another note: what is this muffler system that is being talked about? I have a 3800 SC and it is a little to loud.

Thanks!

I noticed you had recommended the Infinity 50.7 which is now discontinued, do you by chance know if the 50.9CS larger magnet will interfere on the driver's side?



Looks very good Will. But I'd have cut the holes after buying the speaker set,
because they should be sized for the tweeter and midrange you will be installing.

There can be fitment problems with larger magnets - interference with the HVAC duct.
Nothing that can't be fixed with a heat gun.

Thanks for the tip on the heat gun Tony I received my speakers Sat. and the components fit perfectly. I have been waiting on the stereo upgrade as my head unit needs be upgraded as well. The rear speakers will be next. I haven't really decided what I am going to do about subs at this point.

what's a good rear 4x6 (infinity, want to stick with the same brand as 507CS) to complement the 5.25?

thanks

Refer to this thread: http://www.fiero.nl/forum/A...090907-2-088293.html
I have a Reference 462.1cf set in my GT - now discontinued. http://www.crutchfield.com/...y-Kappa-462-1cf.html

There's a lot less choice in 4"x6" plates than there used to be. Infinity, Polk Audio, Pioneer are usually good brands.

But magnet size and depth is critical because there is minimal room in the sail panel - TOO BIG a magnet won't fit.

This Pioneer looks good. Anyone using this???
http://www.onlinecarstereo....Ko3q8CFQZ_hwodBEhpBQ

JBL 4x6 plates appear to be really deep (about 1-3/4" maximum will fit)


This INFINITY REF 6432CFP has a monster sized magnet that I don't imagine will fit.

HUGE magnets. Of course you'd have to figure out how to mount a 4"x6" plate in a 4"x10" hole.

      I printed the template and cut the driver's side plate today. I got a pair of Sony Xplod 5.25" 4-ways. It looks like I'm going to have to cut the factory holes in the dash a little bigger to fit the cones. Luckily I got a big 2'x4' piece of hardboard, so I have plenty to experiment with. I had to call it a day after one though, because I borrowed my friend's jigsaw, and it must have had the original blade in it! I didn't feel like going back to Home Depot, so I wrapped it up for the day. Has anyone else had to modify the dash openings to fit their speakers in?

carbon MSG #45, 08-13-2014 12:16 PM
      I did, just a bit though... the bigger modification was the HVAC duct on the driver side.

I should have bought neodymium... for both the front and the back. Oh well... hindsight.


PatrickTRoof (roof.patrick@gmail.com) MSG #46, 08-13-2014 04:10 PM
      I did the driver side today. It turned into a can of worms. I drilled all the holes according to the template. I should have waited to see where the speaker's mounts were. I did end up trimming the dash a little bit. Also, the factory grille doesn't sit quite right because of the extra tweeters on the speaker (I got Sony Xplod 4-ways). Tomorrow I'll do the passenger side, and measure everything twice.
