Replacement for the 8" sub

Recommended Posts

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?

What would be the correct replacement for a 2014? What are the wattage ratings and at what ohm rating for the single sub?

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.

Aren't the OE subs 2 ohms? 

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.

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.

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.
