8 x 12"s in Ford Explorer Sport


Recommended Posts

Posted

So Im about to start a new build very soon and i wanted to post it up on here and get some insight from professionals and enthusiasts alike. Please, feel free to post whatever is on your mind, whether you think it sucks or that it will be good, your opinion will be appreciated.

Okay, Here we go...Electrical first:

Front batt - XS Power D6500

Back batt - Shuriken BT80 (i think that the official name for it)

Alternator - DC Power Inc. 185 amp h/o alt (OEM fit for explorer)

Power Wire - 2/0 Sky High OFC

Sub Amp - Hifonics BRX 2400.D (final impendence of 1 ohm)

Mid/Highs amp - Skar SK 85.4

Big 3 done in the 2/0 sky high

Now for the drivers:

8 x 12" Hifonics HFX12D4 - 300W RMS each

- Fs 30.33 Hz

- Qts - 0.638

- Xmax - 6.5mm

- Mms - 111 grams

- 1.25 cu ft required for sealed box, 1.6 - 2 cu ft for ported.

4 x Alpine Type-R door speakers (2 in front, 2 in back.)

Box design is coming from Ryan Miskin at RAM Audio. Its looking like it will be a 4th order bandpass with the ported side tuned to about 45 hz.

(someone told me that if i had the port facing forward toward the windshield, i could seal around the box making a "wall") i have no idea how true this is, so i wanted to include it and get some insight on this.

As of now, i believe that is everything...but im sure that i have left something out somewhere. if there is anything that i need to clear up, please let me know. Thanks to everyone in advance for taking the time to read this and help me out.

I don't claim to know how to solve anything, I just practice the basics. There is nothing worse than wasting hours over a problem that should have taken 5 mins. Anything I post and claim to know, I know simply because of a lesson learned from a mistake on my part.

I would look at a bigger alt for future upgrades.

band pass 4th orders tend to take some testing to get the sealed and ported sides right.

if you were to do a simple ported box you could easily cut the front/baffle of the wall out and make the box bigger or smaller to accommodate bigger better subs for upgrades.

1 t600.4

1 t400.2

singer alt, tons of wiring, smd vm-1, 80prs, back seat delete, still in the works, aiming for a 145-147 with the ability to play 25hz up to 50hz.
