17 Discovery Sport - Subwoofer Install

Theres been a couple hints regarding people wanting to install a sub in their Disco Sport but haven't seen anyone do it yet. My 17 SE upgraded stereo lacked a bottom end so I decided to have a talk with service and pursue a simple sub install. Here's what I came up with.

Amp: Alpine 300w Class D monoblock MRV-M500
Sub: Pioneer 10" Shallow Mount TS-SW2501S2|S4
Box type: Sealed .3cu ft fiberglass enclosure w/ 3/4" MDF baffle
Box location (factory sub, passenger cargo area)
Wiring: 4ga power, 12ga speaker

OEM speaker wires to tap:
Driver FL Bass
+ White / Violet
- White / Orange

Driver FR Bass
+ White
- White / Brown


I'm not extremely satisfied with the Pioneer 10" but for 60 bucks on Amazon, what do you expect? I might upgrade to a Dayton Audio DVC 10" if it'll fit within the Q numbers of my tiny box.




Power wire ran to the battery. Hidden under the OEM cowl



Power wire poked through the OEM cluster master Cylinder grommet Ran through loom for foot protection and chase the driver kick panel.



Wire continues to run in the OEM harness chase to under the driver seat



Speaker level input tapped from the front mid-bass drivers. Soldered, tapped and zip tied. Color codes listed above.



Bass Knob wiring ran behind the center console shelf. Phone cord tied tightly and ran under the carpet using the factory harness chase.



Bass Knob double side tapped in hidden view



Speake wire ran to the back using the OEM chase. This one was a bit tricky. You can see the 12ga romex I used as a pull. After it wraps around the spare tire well to the rear cargo area. No panels pulled which was nice.



Factory Amp location under the driver seat. The Alpine Class D sits nicely next to it. Only suspended by open cell foam for noise. This amp runs cool so am not worried about heat issues.



Box area tapped for glass mold.



Initial mold made. I re-fitted the mold again and glassed 3 additional layers for strength.



Front baffle cut and fiberglassed to the existing box.

I did SQ competitions back in my 20's. I really liked the Disco Sport but have to say even the 380w Meridian stereo is crying for a little bottom end. For anyone who didn't want to build a custom box, there are plenty of shallow subwoofers + shallow boxes and would fit in the spare tire area. OR build one out of MDF as a weekend project

I have the basic stereo in mine. Bought the car off the lot. So I would like to eventually add a XM receiver and a sub.... eventually. Maybe something to raise the boost on the Turbo as well.

I had one done and its awesome!! They did an professional job hiding it behind the rear passenger side seat, amps and processor in the wheel well and still can have a spare in it. 800 watt Audison controlled It rocks now.

Both look nice and not sure what the sound is like in either. But I do like the way the speakers are hidden with Imdomino's setup they look like factory. But the work on the new enclosure sure makes some use out of the little nook in the trunk.

IN the UK owners are told if they even change a rear lamp to LED it could in validate the warranty. LOL

Hello,
There is something to consider when you disconnect the battery to expand the seat?
Disconnect the battery minus 30 minutes and wait for the airbags.
Can the minus then simply re-attach? Or something has to be programmed again or Navi memory card again? Enter a reactivation code?

Looks Sweet. I do Miss my LR4 Premium audio with the 8 inch sub under the seat. The upgraded audio in this is decent but i agree missing the punch.
