So apparently My port was off 3.5" now correct me if I'm wrong but the underlined part is that the ft^3 of space in my box? If it is I should probably make the box a bit smaller? as its recommended 2.5 to 3.75 ft^3 ?

Maybe im wrong with this but it would be 26 Hz before the adding in the sub displacement and the bracing displacements, so Empty It would be nearly 26 Hz but adding 2 15" Subs alone take up a lot of space reducing the actual tune of the box? Or maybe I'm just over thinking it.

This thing is killing me I'm close to just ditching the port and going with a Sealed enclosure

Just spent the past hour trying to understand the entire deal with box specs and this is what I got Didn't really do any displacement math which is why I put in the Tuning Freq. at 26 Figured after all displacements highest it'd be would be at highest around 35 Hz Anyone see any design flaws with this? The Box is going in a 2002 Jeep Grand Cherokee Laredo and I listen to Rock/Rap but more so Rap music.

Alright ill run out to my jeep real quick and take them (Probably not a good idea since its 4 AM and extremely windy, anyways will be edited into this post within 5 mins.) Dont really care if I have any cargo space left as long as I have my backseats.

Yeah its for the Obsidian 15's, and I'll keep searching.

I still don't see a port width which I'm assuming is 3". Its 3 1/2" its in the last sketch I posted.

I second this, especially since this just happened to me I had a budget of around $300 and after purchasing my Jeep I realized I had more of a $500 budget.

Yeah I clicked post too fast fixed now.

Welp went to Home Depot picked up some 3/4 MDF Today (Way more expensive then I remember $34 a sheet) right now I'm searching around for Box designs so far I've found Which is 5.96 cubes tuned to 33hz (Posted on Realmofexcursion? Forum by profundus-sanus.) meets the recommended air space, and is only 1hz off the recommended tune. Only thing I haven't been able to find is there any benefit of having the port on the side? (Although I haven't searched on this much yet.)

Good point, ordering the 15s tomorrow and some wood/wire, guess ill get it all staged so when the subs come I can just drop and go.

I'm definitely lost in a world of sub woofers currently, I think I narrowed it down to either 2 15" Obsidian D4s or 2 SA10 D4's Anyone have direct experience with the 2 sub woofers willing to give me a little push in a certain direction? (And not sure if I mentioned this going more for SPL then SQ)

I see Sundown offers a replacement at a reduced price if you've caused damage to the sub woofers from misuse. Anyone aware of how reduced this price actually is?

See now I'm gonna get in one of those stalemates where I'm going to start looking at 20 different woofers and have trouble deciding which to go with, those Obsidian 15s look like a pretty good deal though @ $365.43 for 2 Im thinking im still gonna go with the 2 SA 10 D4s

Wouldn't really say there's no such thing as under powering because you can blatantly under power for example putting a sub that can handle say 2000 rms on an amp that only pushes say 500 rms. Also I was talking about a difference within the speakers not so much the amp.

I mean I've never actually heard Sundowns in person, is there difference between the E10 SD2 and SA10 Extremely noticeable ? I'm not trying to be cheap, but at the same time I'm not trying to break the bank for minimal gain.

Alright well since my amp @ 2 ohms pushes 1000 watts and @ 1 ohm pushes 1500 which should I go with overpower or under power? (This is going off the amps specs and not the actual output of the amp as I have yet to test it) Considering based on this it kinda chooses whether to go with the D4 or D2 I Know once I add an additional 2 10"s to my setup I'll have to upgrade the amp but currently Im only looking to upgrade my subs

Hey guys last night I blew my REX10D4's in my 2002 Jeep Grand Cherokee Laredo So here my current situation, I have Kicker DS693's in the front doors and DS65's in the back doors. I was running the REX10's with a Hifonics 1500D @ 4 Ohms which was overpowering them a bit but meh happens.(Amp is 1 Ohm stable) Alright so heres the dilemma I'm looking at either SA10s or E10s.(I listen to Rap/Rock) Currently I have a 3/4 MDF 2.0 cu ft box with 2 separate chambers and L ports tuned to 38 Hz (Also have a Sealed box laying around with .69 cu ft per chamber I believe) Now I'm only currently purchasing 2 with the intent of purchasing another 2 in the future. But I'm unsure which ones will best fit my setup. (Sorry for the kind of broken sentences but was trying to provide details without giving a wall of text, I'm sure even with trying to provide everything I've still forgotten something though)

Yeah I've pretty much got it narrowed down to Sundown just gotta pick which series to go with. (You'll see a thread with me explaining details of my setup and asking for suggestions instead of picking what evers cheapest and having a shitty system)

Currently have a Hifonics 1500D running 2 (Blown) RE Audio REX10D4(Was looking for an excuse to buy new subs so I had a little fun) and KICKER DS693(Front) DS65(Rear) in the doors.

Sup guys always love car audio but previously was into more entry level stuff trying to step it up a bit
