Sundown SD-3 12" Sub for RAM 1500 Crew Cab

Jose Zayas · May 20, 2018

I want to integrate a sub in my RAM 1500. I’m looking for good sound nothing competition or blasting power. I have been looking at the Sundown SD-3 12” sub because I think my Alpine MRV-M500 will do fine with it. The problem is to find an enclosure that meets the requirements. I have been looking at the FOX Acoustic single sub sealed and ported. The sealed box has .95 cubic feet and the SD-3 requires 1.0 cubic feet. Does the .05 cubic feet make a difference? The ported box is 1.85 cubic feet and the SD-3 requires 1.75 cubic feet. The porter box meets the space requirement plus .10 cubic feet that I think the sub displacement will utilize. But the Fox 12” ported box is tuned to 36hz and the SD-3 requires 32hz. How this difference in tuning will affect the sound? Can I make any of these 2 boxes work fine with the SD-3 sub? I’m leaning toward the fox box because I don’t want at this point spend too much in an enclosure and for the price it seems to be alright. The rest of my system includes an Alpine MRV-F300 powering a set of JL Audio C2-650 6.5” Component for the front and JL Audio C2-690tx 6x9 in the back doors. No DSP or active set up for now. Thanks, will appreciate any thoughts.

I believe those subs are on the list of recommended subs for fox box on their site.

In the sealed, you could add a little polyfill to make up the slight difference if it really bothers you. I don’t think .1 cuft is going to make that much difference.

On the ported enclosure you could glue in a wood block to take up the extra space. I don’t know enough about boxes to know how placement of a block would affect the sound.

I love my NetAudio box. They are more expensive but definitely worth it. Their website seems to be having issues at the moment but their Facebook page is working.

Is it possible to change out the factory sub with an aftermarket sub and amp? I don’t want to change out the factory 8.4

I kept my stock head unit and just removed my oem sub and box and went with a fox box with an alpine type r 10” sub

Sundown Audio SA-12 D4 fits the fox boxes also, hard hitting and sound amazing!

I want to know what grills those half moon cutouts are for, I’ve emailed fox a dozen times they don’t care about me now that I have the box. It looks like it will fit one of 3 bar types but which one!

Look o at 4 and 10’oclock around the woofers there are intentional cutouts, they just have to be for a 3 bar style grill. I think they measure 13 7/8 inches but I can’t figure out on amazon which ones they are for.

appzattak · May 22, 2018

ahhh, I see. I couldn't put anything there, not with these woofers anyway.

Most of them are tall enough for high excursion and only have a footprint of 3/8 inch I just want to give my type s some room to enjoy themselves.

Also how are you enjoying the sun downs I just couldn’t buy a brand I’ve never heard in person before I was heart torn between the type S and the Fosgate P3

I like the SA12 a lot. Reminds me of the idmax 12...it can def get rowdy, but be pretty musical as well. Is that a vented Foxbox or a sealed box??

After displacement, that sub should fit just fine in the ported enclosure. It should sound just fine tuned to 36hz. I had a similar situation but with just a 10". I wound up getting an RE Audio for mine and it sounds good. Im sure the sd3 will sound just fine in that enclosure as well.

I don’t know about his, but I have the ported and it does not mess around. Best $250 bucks I have invested in my sound system.

Yea, the SA12 does very well and prefers a ported enclosure, kinda wondering how it responds to a sealed enclosure. Im sure it handcuffs it a bit, but that might not be a deal breaker
