Sold the 04 Yukon with 2 18 Fi BTL NEO's and a Wolfram 4500
Had the system in a 30hz @ 14ft^3 box with a bit too much port area. Was only hitting 147/148's which isnt terrible for 30hz but I was hoping to hit 50's... which is the reason for the rebuild.
less port, smaller box, more layers of wood and higher tuning. Hoping to get a 152-153 @ 32hz.

Bought a 08 Tahoe LTZ and upgraded to 2 18 Fi Neo 4.11's and a Sundown 7500

(2) 18" Fi Neo 4.11's
SCV 7500 @ .4 (eventually (two) @ 1 ohm)
Limitless Lithium Gorilla G30 (eventually (two))
Mechman 320a Alternator
Stock Alt Running The Vehicle (so dual alts)
(4) Runs 0/2 Welding Cable Front to Back
(6) Toro Audio 3way Coaxials
Toro 6.5 Components in the Front
(2) Skar RP75.4 (eventually (2) SAX 100.4's)
C Pillar Flat Wall 32hz @ 12ft^3 (was going to do a 4th but I guess the 4.11's dont like sealed much.)
Build In Progress will be updating as I go. Reason for the Lithium is eventually will be adding a second G30 and a second SCV 7500 one per sub totaling around 15-16kw.

Very nice build. Should sound amazing. Tracking!

Some of the cuts were off cause I had to do some of it with a jigsaw o.O but it will all be hidden with rhino line. The top beauty panel had a little glue come through the cracks, will also be covered with rhino line, you wont see any of it.

Next up is fiberglassing the side beauty panels, getting the door speakers all installed, then amps/batts and the alt/wire runs. Should be done soon! will keep posting! Also the top headliner is going to get some Black RV sealer along the edge so it wont look so haggard.

wow

You're gonna be the guy I'm jealous of at stoplights lmao, awesome build!

Thanks guys

I had lost a bit of motivation and funding for the project. I managed to nearly finish the beauty panels but the cold has slowed me down quite a bit (its 30-40f in NE atm)

I will post pictures of the panels in the coming week. Wire has been ran already, need to install the door speakers and amplifiers and finish up the rear with the battery etc.

I predict another few months before completion, was hoping to have it done before winter but the car needed work

can't wait to see the finished product man!

My 2 12s from the trunk were louder than your first setup, TBH I have never been a fan of Fi subs I think they’re pretty inefficient compared to what’s out now but to each their own. That sundown amp is a solid power plant though, should be nice brother

Starts off with an insult, ends with a compliment. lol thanks?
