What do you guys think about putting the sundown sd-3 10" in the thunderform box, if I can get a hold of one? According to researching, it's almost a perfect fit. Not cheap though. Of course not with the factory amp. Or what do you guys think for the biggest baboom to fit in there?

Is it a shallow mount? It needs to be in order to fit. Also figure in the recommended sealed enclosure volume. I fount a JL that fit the bill. It hits pretty hard with an amp.

It is their shallow mount that will fit. Which JL sub?

the mb quart discus 8 (DS1-204) is a drop in, so long as you leave the trim ring off. 8.25 (8.43 with ring) outer diameter, 7.24 cutout. which is well within tolerances for the oem 8 box. rated at 200w rms, 400 max. 2.8" mounting depth.

I got the kicker conp rt8 and it is pretty damn good. I don't listen to much music with lots of bass. But I was tired of having none in there. I am waiting till next month to order a separate amp to run the sub. The kicker fit perfectly in the stock box. Seems as tho it does need a little more room to get a good boom but, all in all it works out quite well.

I bought the 2ohms per coil kicker. At the time I didn't know there was a 1ohm per coil sub... But, thanks to "Sub" (the Subwoofer master on this post) I learned a whole bunch of stuff that I didn't know before. So my kicker is only running off 1 coil technically. But for a Yukon xl you know the sub is 8' away and still hits pretty good.

hi man, did it fit with no modifications on the enclosure box what so ever? no removing of ring cover of the sub? no holes drilling for screws? what is the full name of the kicker sub? is it Kicker 48CWRT84 on Crutchfield Website?

Hey I know this is a late reply, but the new 48 series (designed Kicker's 48th year as a business) CompRT is actually 8.5", however, there's the plastic ring all the way around it. You'll have to cut the side towards the top so you can peel the outer ring off. It takes ~2 min with a Dremel cutting wheel but it brings it down to size to where it's a snug fit. It's really easy to do but if you're not wanting to do it the MB Quart does ok on the factory amp. I'll be installing this one pictured on the 16th and can update then if you want to see it. This is actually the D2 version that'll be wired to 1ohm for an aftermarket amp. It'll be on a Kicker 5 channel that's only rated for 2 ohm on the sub channel but the D2's still do better and the CXA660.5 is a tough amp, it can handle it. It's like a CXA360.4 and a CXA400.1 (rated at 1 ohm) crammed into a single chassis. If doing stock amp though, that D4 is the one you want to use, I wouldn't run that factory amp at 1 ohm.

If you do the modification, be sure to cover the holes so you don't get stuff flying into the driver.

Hi all, would like to chip in on subwoofer fitments. I have a GMT800 2002 Suburban (No Bose). Sub box OEM # 15766433. Wanted to maintain brand consistency, so had to get a Rockford Fosgate Sub. The model is an 8" P3SD2-8 (RF, Crutchfield). There are 2 shallow-mount 8" models, a Dual 2 Ohm and a Dual 4 Ohm. The depth is not a problem. The OEM holes do not line up, drill small pilot holes and choose screws with a proper head diameter to fit flush unto the mount of choice. Washers can be used if small enough that it won't rub against the suspension (flexing rubber), otherwise, small screws should suffice. The thickness of the outer mount ring (where the screw head sits flush) plus the thickness of the box is ~13mm, so any screw of at least this length should be enough. For those who want to keep as OEM as possible, the OEM terminals inside the box are female spades of 4.8mm and 6.3mm, so a kit from amazon/eBay can provide these accessories with male spades with crimping tools.

The sub without its trim ring, has these wavy/ribbed non-circular outer circumference profile that extends slightly beyond the diameter of the OEM drop in hole. It requires a dremel to trim out the protruding notches. Caution on the dremel mess, the plastic particles can be messy, recommended you use eyeglasses and be outdoors with a handheld blower. If you dremel out too far on the notches, you *might* end up bottoming out and possibly drilling a hole, which I did on 2 notches. So I ended up duct taping inside to seal it. Another alternative is to cut the notches on the speaker itself too to keep the OEM box factory. Thanks.

I picked up a factory box from a 00-02 suburban at the local LKQ for $14 on their half off black Friday sale yesterday. Of course the sub was no good. It just so happens that I had a Rockford Fosgate PS-8 combo amp/sub that has never sounded right. So I took that woofer out and it fits perfectly in the factory box. No cutting or dremmeling needed. I never had the factory sub so not sure how it would sound on the factory amp. I'm running it with a RF Punch 300. Works great. Pick up a non-functional PS-8 on eBay for peanuts and use the woofer. Happy Thanksgiving!
