ST165 Speaker Fitment Guide

Edited this post to contain data for quick reference. Pictures are seen in the replies below.

Image
"A" is the overall nominal diameter. This is about how wide you can go with a speaker's overall outer diameter.
"B" is the cutout diameter. This is how wide the hole needs to be for the speaker to sit on its mounting flange.
"C" is the nominal depth. This is an approximation of how deep of a speaker you can fit. Note that the OEM pods have contours and may not fit everything. Nominal measurements are taken at the center of where a speaker will rest.

Well first off, neither of those sizes are stock for a 165. The factory fronts are 3" and the rears are 4". Anything bigger will require customizing the boxes. There's probably writeups or photos of such around on the site. I've seen mention of a few people managing as big as 6.5" in the rear. It'd be nice to get all that info centralized though!

Thanks for the input! What is the largest speaker that can fit into the stock mounting areas? Any issues with depth?

Once I sell my car and or find the right ST165 Alltrac, I'll do what I can to update this this thread. I've got a little project in mind to maximize the audio department in these little cars since they are nowhere near as peppy as what I am selling. Gotta have something to tinker with!

Four inch ones won't be hard to adapt to the front boxes. It'll take a little finagling but they can fit in the stock location I believe...I'm about to do that on my own ones. Depth won't be an issue. The front boxes are about 5 inches deep or so. The rears are closer to 6 or 7 inches of usable depth. If you need I can snap pictures of them this afternoon. I have a pair of 6.5" speakers I inherited for free so I'll be working on a way to adapt those to the rear boxes myself. :)

Finally removed the rest of the speaker pods and took some measurements:

The rears dont look like the have any room for addition.

The fronts seem to have a little. And what is the flat speaker thing?

If you cut and hack the speaker pods you can fit a larger driver inside, but honestly a smaller driver that fits will most likely sound better in its enclosure. The flat speaker unit is called a passive speaker. It moves as pressure changes from the main driver. This effectively makes the surface area of the speaker larger, but also changes the phase of the driver. I don't know much about these so I still plan to eliminate mine with a block off of some kind. The long term plan is to have a proper 6.5" driver mounted in the door and to use the front enclosures as mid drivers.

Can we make this thread a sticky for fellow ST165 owners?

+1

Seems sticky worthy for this area and good for use who have crappy speaker options lol.

Going to update this thread as I've been making some progress on this recently.

Here are the front enclosures. Meant to order the 4 ohm driver for this. The driver fits perfectly and has a good tone, but needs a tweeter near ear level to keep the sound more natural. For a drop in speaker this works very well and I would recommend it. Here is a link to the 4 ohm version: http://www.parts-express.com/pe/showdet ... 0-4%204%22

Here is the rear speaker setup. I used an Alpine SPX-137r speaker for this. It fits very well and matches the required enclosure dimensions perfectly. Only change needed is that the driver works best in a sealed enclosure instead of the ported OEM one. A block off plate is easy to make and is a bolt in affair which equates to a simple installation. I will be making changes to the setup as I need to install the crossovers and tweeters in the near future.

Image

Future plans may involve replacing the Alpine speakers with something that acts more as a woofer as opposed to a midrange. This speaker will be a snug fit but could work with a .5" spacer: http://www.parts-express.com/pe/showdet ... er=264-878

Quick guide on routing audio cable to the door.

Tools/supplies used:
-Old oil dipstick
-Electrical tape
-Audio cable
-Wire cutters
-Screwdriver (phillips)
-10mm socket with extension

Things to do first:
-Remove the door card. If you need instructions for this step, please just ask and I will post up a quick 'how to' for this. You will also have to peel back the plastic lining.
-Remove the plastic cover that is located in the foot well near the doors. This is a kick panel piece that has a trim with a single phillips screw near the door hinges and may have a single bolt to keep it in place.
-You may or may not need to remove the speaker pods for access. I already had the speaker pods removed for another reason at this point and am unsure if this step is needed.
-Now take the oil dipstick and or a thin piece of metal that you can fish though the rubber boot that goes between the chassis and the door. Just be very careful to avoid ripping the boot.



Image

Once the dipstick is through, tape your audio cables to the dipstick and slowly pull the cable through.

Image

Image

Once its through, be careful where you route the cable as you want to avoid any potential snags when the window lowers.

Image

Finally route the cable where its needed. Here I have one cable that leads to the sail panels as I will have a tweeter placed here. Another cable is left below as I may build a speaker pod on the door card. A little pre-planning goes a long way!

Image

A quick tip when routing multiple cables: To save on the guess work here, cut one cable at an angle, or cut one end shorter to help identify that cable later. Here you can see I have the tweeter cable cut at different lengths. Note that both ends of the cable are cut the same to identify that one from the other.

Nice trick with the dipstick.

I may be trying to do this soon cause I really dont want buy 3.5 or 4 speakers and try and make them work on the front, so may try and find a pod of some sort to make work on the front door.

So what is the official status on speaker size? I am simply looking to upgrade the speakers, looking to spend $100 total on all 4. Nothing fancy, no extra work.

Most websites say 4 up front and 5 in the rear. 5 is not a common size but 5.25 is.

Front speaker measures less than 4" in diameter but is it a 3" or will a 4" still fit?

What about the rear? What is the speaker size? It measures a bit over 4 but is listed as 5.
