I made a YouTube how-to video on replacing stock speakers with aftermarket ones (same size, no dremmel cuts). Thanks ee241 for the recommendations:

I installed a Rockford Fosgate P300 powered sub 2 summers ago and can honestly say it's my favorite modification on the Spark. Nice to rock out and feel the sub on my daily 45 minute commute. Install was super easy; just tap power and pull line level inputs from the rear speakers. And it's slim enough to fit in the trunk, easily outshining any deficiencies/crappiness in the stock speakers.

I figured since nobody can sit in the middle position anyway, that's a good place for the sub. No reduction in leg or foot room, practically invisible wires, and no holes drilled toward the traction battery! Those of you looking to mount an amp may want to consider this position as well.

I'm pretty happy with the result since I can now hear the bottom half of my tunes. :) One thing to be aware of is that the head unit doesn't have a discrete "power on" signal: it uses the GMLAN bus for that. So if your amp does, you'll either need to tie it to the ignition signal, or use a low-voltage trigger which lets it stay on any time the speakers are energized. I opted for the latter so I can still have bass without having the car on.
If I understand this correctly, this is mounted with "Industrial Strength" Velcro?!?! Please realize this is a big no no, a lethal projectile in the event of a crash. No Velcro (that I am aware of) and wires are going to keep a heavy object from going whatever direction force sends it, whenever the vehicle it is "installed" in, goes from <15mph to 0mph in an instant. I'm still MECP Advanced certified by the C.E.A., even though I haven't installed professionally since 2015 (I did 8.5 years big box install full-time), I'm not talking out of my arse.

On a different note, I want affirm what has already been stated/alluded to, there is no way a 4" , 4"x6" , or any speaker with a single voice coil, can produce a "decent" full range of sound. I really liked the pizza analogy someone used, where essentially some people are fine with a frozen red baron (any cheap speakers with limited range, that don't distort at moderate volume will do), some demand fresh organic brick oven pizza (separate high, mid, low speakers to help achieve high fidelity), and everyone else falls somewhere in between.

When I finally acquire a Spark EV (fingers crossed, test drove one, love it), I envision starting off my speaker changes with an old pair of 4" roadmaster two-way speakers (yes, this is most always a garbage "Wal-Mart" brand) that I acquired in a trade, which are amazing for what they are, and a pair of Pioneer TS-X series enclosed 3 ways, probably secure mounted (no velcro) under the driver and front passenger seat, firing backwards. This should achieve a decent range of sound, with little distortion at high volume levels.

Please understand (if you don't already) the law of diminishing returns certainly applies to car audio. If you will settle for nothing less than high fidelity, with high volume, professionally installed, you're well over four figure territory (in this case, you're probably not driving a Spark EV in the first place). On the opposite end of the spectrum, you probably want to stay clear of the flea market/no name stuff, unless you are 100% certain you know what you are getting. Anyone who is willing to give up a chunk of the little bit of rear cargo room that exists, for a decent slim 8 or 10" sub, likely won't be disappointed in the difference I know it will make in this car.

I've learned so much from this forum, and am grateful for everyone who has constructed and contributes to it, Thank you!

I replaced the front and the rear speakers in my 2016 spark ev. with a nice set of polks. I was hoping for a much better sound. Unfortunately I found only a moderate improvement. But at least I can understand the DJ and Talk Radio. 3 inch in Front 4x6 Rear all 4ohm. :)

For those interested ,I made some 3D printable 4x6 adapters to put 5x7 speakers in the rear deck. (BTW, they are screw with no mods required so even if you lease you can undo this addition and put back to stock at the end of your lease.)

https://www.thingiverse.com/thing:2938980

To adapt your rear speakers from the 4x6 small ones and put a larger 5x7 in their place. Mirror for opposite side. Designed for Phoenix Gold SX57CX speakers (Great Speakers, worth the $$) . May want to reduce flange cut depth from 3mm to 1.5mm, Size is 200mm x 146mm x 31.75mm. Will fit on 165mm X 145mm bed if you use the split in half version and use 4x 1/8 diameter pins and epoxy parts together. Original solid works file included for customization. (see thingiverse link for files)

Also, the hardest part of running wires to the front of the car is removing the side rear airbag to run wires for the amp / remote / front speakers etc. Look them up on ebay (for pictures) and you can see where the loop is that "pops" in place. It takes ALOT of force to pop it up, but once you have it out of the way running the wires is pretty easy.

This thread has been great, I feel like I need to go back and read it a few times to get all the info. Has anyone been able to find out any official stats on the stock head unit? All it seems we know is that the front channels are 8 ohms, back are 4 ohms, and all stock speakers are stamped with 40 watts (RMS I assume). I'm debating between adding just a powered sub and back speakers, or replacing the front as well with a small amp that will run all four speakers at 4 ohms and a known/planned wattage. I don't know what frequency response the stock front speakers have either, does anyone have an idea?

Anyway, subwoofer placement. I don't want it anywhere that could get in the way of cargo, and I don't want to cut into the foam under the trunk because I want that charger to stay in there for emergencies (also I don't like permanent modding), so this is what I've come up with so far (thanks to earlier guy who gave me the idea). I would anchor it, which begs the next question... Does anyone think I could safely screw it in without puncturing any kind of battery area. :P It fits pretty well under the backs of the front seats, however we're a family with big feet and it gets in the way of that.

Have any of you who have installed 4 ohm speakers in the front noticed any issues? Warm head unit maybe?
