No I do not notice a significant noise difference.

This is a brief run down of my 2013 Ford Fusion Hybrid SE w/ Sync install: (1) Sun Down Audio 8" speaker (eBay E8v3D4 SUNDOWN AUDIO PRO 8" SUB DVC 4 OHM 300W) (1) 8" ported box (eBay under 50 dollars, fits perfect above the hybrid battery 8" SINGLE PORTED L-VENTED 3/4 MDF GREY SUBWOOFER SUB SPEAKER ENCLOSURE BOX) (1) Soundstream nano 1.650 amp (eBay SOUNDSTREAM PN1.650D 650 WATT RMS PICASSO NANO CLASS D MONOBLOCK AMPLIFIER) (1) Line Out Converter (LOC) (1) 100' roll of speaker wire (1) Amp install kit To start I tagged the front speaker wires which were easier to access right under the "Fusion" plastic piece on the floor. (Front speakers are twisted together, Drivers side front speaker White (+) and White Brown (-). Passenger side White Violet (+) and White Orange (-). On the drivers side I also found a switched 12V white with light purple stripe that sees 12V when the key is put in, not even turned on and holds 12V until the car is turned off key not even removed. Ran speaker wire to the 2 front speakers and a Remote turn on wire to the Wht/Lt Purple wire. wrapped all speaker wire in black hockey tape (looks more professional and I use to install and wanted it to look stock). Tucked wire under carpet and panels. Ran wires respectively under the rear seat and into trunk under the hybrid battery carpet. Removed false floor carpet cover that covers the flat repair kit. cut the Styrofoam to custom fit my Soundstream amp. Ran 8 gauge power wire from battery again under the carpet to the amp. Connected Amp, LOC and Sub woofer. Adjusted gain, Bass boost, LPF and Sub Sonic filter. I liked that the sub woofer can be up on the hybrid battery out of the way, and can easily be placed closer to the trunk lid for loader bass. Test run sounded good, it's not a pair of Kicker L7 12's but first time I can actually say WOW that's amazing for an 8" sub. Sun Down Audio is amazing. -When driving I noticed a ridiculous thumping coming from the sub when ever the gas engine would turn on.... Thought I was clipping, turns out itt was the Active Noise Cancelling turning on, which brings me to why I used the front speakers.. Unscrew the "Oh Sh*t" handles on the head liner, pull the A-pillar plastic slightly off... You can see the small mic above your head on both the driver and passenger side. Others claimed to unhook the harness, but that would involve taking more off to remove the headliner, and I didn't want to damage or crease the headliner. I cut the black wire going to the mics and replaced the handles and pushed the A-pillar back into place. Problem solved. Very happy with how this install went. No problems to report as of a week of use. Picture attachments: -Drivers speaker wires and Wht/Lt.Purp Remote turn on wire. -Installed Sun Down Sub above hybrid battery. -Active Noise Cancelling mic location there are 3 in the vehicle I only disabled the 2 front ones that are located by the handles. There is a rear one above the rear window in the center, but if you tag the front speakers the rear one does not seem to affect the sound output. Hope this helps some of you. -M1xMstr
