No such thing I ran 2 3518s and 1 Maxximus in my Hyundai. All I did was double it up. DD makes a lovely speaker -

yes and yes I'll post them here for ya in a second. Actually no the HF1415s I don't have yet. I'll have all those in 2 weeks -
Here's a little sketch of what's going in my van sometime during the next few weeks, after it warms up some. I over compensated a little for the bracing I might add. Which will take anywhere from .5 - 1.5 cubic feet. So my enclosure volume may go up and tuning frequency may drop but its going to be between 35-36 Hz and 24.11-25.xx cubic feet net. [box] Outer Dimensions Height: 41" Width: 52.75" Depth: 35" [Port] Inner Dimensions Height: 39.5" Width: 14" Length: 20" Equipment Subs: (4) Digital Designs 3500 series 18s Dual 2 Amps: (2) Hifonics XX Maxximus 10,000 rms @ 14.4v

Ok now it all makes sense to me. My last ported box was tuned to 45Hz and my car peaked at 57Hz. So basically I needed to tune my box to about 55Hz to get the full benefit of using a vented enclosure(in an SPL sense). So if I were to tune to 25Hz with the exact same box I would have the same score as the 45Hz box because of the fact that my car liked 57Hz anyway. Please correct me where I'm wrong.

this here is exactly what i'm asking to be explained. The science behind the port says that at frequencies around the tuning frequency of the box the subwoofer will have less excursion resulting in more subwoofer control. But it doesn't explain why tuning to 40hz will give you a higher score than 30Hz
-
I understand most of it. but I've never tested it for myself. They generally say if you're going for SQ and tuning around 30Hz it will decrease your overall score. I know a guy who raised his tuning from low 30 something to maybe mid-high 40 (judging by the port) and dropped. So I'm just trying to understand the science

I'm looking to do nothing more but put up godly numbers without being in an extreme class. Based on my research and prior experience I've concluded that I need a small box with a huge port and a high tuning frequency. So I'm planning to make a wall 17.56 ft3 @ 65Hz with 543 in2 of port area Suggestions?
-
Just saying in general. DB drag rules say you can't play lower than 20 Hz or higher than 80Hz. which score higher on Term Lab? Higher frequencies or lower frequencies?
-
40 Hz and below or 41 and up?

I have a DMM. I know it wasn't smart but I hooked it up the over the weekend and played with it for an hour or so. Using 4 gauge power cable from my old RF Amp kit, the Kinetik HC2000 and a Duralast 1000 CA battery I borrowed. The Maxximus has 4 hots and 4 grounds I kept each connection no longer than 8 inches in length directly to the battery. No alternator just those 2 batteries in the trunk played the whole time without dropping below 12.2v
