NorthroadCreations Report post Posted October 1, 2021 Kind of wondering if there are any good plug and play replacements for the factory sub in my 2017 edge sport. Found a thread from 2017ish, but the Kicker they mentioned was discontinued then. Went to Crutchfield and they showed some options, but wasn't sure they'd be plug and play. Anyone done an 8" swap, or have ideas? Share this post Link to post Share on other sites
wewsel Report post Posted February 22, 2022 What would be the correct replacement for a 2014? What are the wattage ratings and at what ohm rating for the single sub? Share this post Link to post Share on other sites
chipdog4 Report post Posted July 24, 2022 (edited) I'll be upgrading my 2019 Bang & Olufsen sub in the near future. Wanted to check out what was in there currently. It's a dual voice coil. Measure 4 ohms. The mounting depth is very shallow 3 1/2" This box looks to be easier to modify for a slightly deeper sub than the 15-18 Sony enclosure with the molded nub behind the sub. Here's a photo of the 15-18 Sony enclosure Here's the 19-22 B&O enclosure. (picture rotated on me) The reinforcement webbing could be sanded down for a deeper sub (probably get a 1/4" and a then quite a few more subwoofer choices.) Dual voice coil, 4 ohms each The subs above will work, in the 4 ohm version.

The 2015-2018 Sony subwoofers probably were, but everything I could find for the newer B&O subs in other Fords said they were 4 ohms. So I measured mine to make sure. And I went ahead and bought one of the MB Quart subs. Not sure when I'll get around to installing it. Edited July 28, 2022 by chipdog4 Share this post Link to post Share on other sites
chipdog4 Report post Posted January 19 I removed the factory sub and installed the MB Quart 8". Not a huge difference in sound. I can feel the bass a little more and there's no distortion at any volume. Was it worth the $60 and the time to install it? Possibly I was in a rush and didn't take any pictures. I did shove a couple handfuls of polyfill in the enclosure before sealing up the sub. From this thread, " Coil #1 Purple/Blue is Positive, Yellow/Blue is Negative. Coil #2 Yellow/Purple is Positive, Green/Blue is Negative. " I had Yellow and Purple on one coil and Green and Black on the other coil (all solid colors, no stripes). Black and (IIRC) purple were negative, yellow and green were positve. Share this post Link to post Share on other sites

I can feel the bass a little more and there's no distortion at any volume. Was it worth the $60 and the time to install it? Possibly The 2-ohm coil will deliver high sound output (2 ohm draws more current than 4-ohms), but may distort at high volume (depending on quality). The one in my 09 MKX with THX doesn't distort). A 4-ohm speaker isn't as loud (after all it draws 1/2 the current as a 2-ohm) but it also won't distort at high volumes. A lot has to do with the design of the amp. Usually if the amp and speaker are designed as a matching pair there shouldn't be any problems. As the speakers are rated in impedance and not resistance, you can't measure it by ohming it with a VOM. Share this post Link to post Share on other sites
Edge_u_Cational Report post Posted Sunday at 08:51 PM I need to pull mine out and measure the enclosure volume. this will determine what subwoofers can be swapped in successfully. I'll probably sweep the stock woofer since I'm in there and have the gear to do it it looks like the JL Stealthbox takes advantage of a bit more area and might have more volume. I'd really like a 10" back there if possible. I'll post my results here. Share this post Link to post Share on other sites
Edge_u_Cational Report post Posted Monday at 07:51 PM (edited) so, added about 10lbs of mass with some killmat to the exterior covered the outer rear with closed cell foam so it compressed to the body when bolted in added some stuffing. bass now set to 0 for my taste [was at +3] it's pretty good now. the enclosure doesn't resonate and that's a good thing. all that energy is now bass output here is the impedance sweep and T/S measurements of the driver in enclosure, sorry i didn't have the stuff to measure the enclosure volume https://imgur.com/a/K2ZOkvE Edited Monday at 07:54 PM by Edge_u_Cational Share this post Link to post Share on other sites
Edge_u_Cational Report post Posted Monday at 07:55 PM i can break out the mic and do output sweeps tomorrow and check distortion. Share this post Link to post Share on other sites
