I'm compiling the info I've been getting. Please, check me on my thoughts and let me know if I'm off track anywhere.
So on Skar's site, suggested box size is 1.25^3 for a ported enclosure. Sealed is significantly smaller at .65^3.
Crescendo says that the amp will put out 3875 @ 1 ohm, 1900 @ 2 ohm, and 1150 @ 4 ohm.
Here are a couple hypothetical situations. Getting numbers from the12volt.
1 - 4 of these subs, wired for RMS wattage about 3600 @ 1 ohm final load.
2 - 3 of these subs, wired for RMS wattage about 2700 @ 1.34 ohm final load
3 - 2 of these subs, wired for RMS wattage about 1800 @ 2 ohm final load
4 - 1 sub, wired for RMS wattage about 900 @ 4 ohm final load
My thoughts on those options.
1 - I would LOVE to be able to put 4 of these in the truck for the wow factor and some killer power. But I'm not sure that is a realistic goal without giving up truck function, having to spend too much money I wasn't planning to spend, and a lot of work.
2 - Not really any more likely to work than 4. But leaves me with an even number of subs to sell.
3 - Seems the most realistic of the options without sacrificing too much sound. No it isn't 4, but still almost as much RMS wattage as I had back in the day with my RFR3112s.
4 - Definitely the easiest to build for. Just not sure how pleased I would be with the output of a single sub of this stature. Also, feel like that is a lot of amp to be used on a single 8" sub.
Some questions for clarification
Is it true that the higher the ohm final load, the less stress there is on components?
Alright, this may be a ridiculous question, but has anyone cut out floor and made more space? I could lift my seats a bit, but don't think I can get near enough to either fire subs up or down. I am a metal fabricator and possess all the tools and ability to effectively increase the volume of my floor pan in the cab to accommodate a custom build, but I wouldn't want to delve into that unless I know for sure it would be worthwhile. That is a LOT of work to do right. But being that would move the drivers or the cones "outside" the regular square area of the cab, would that affect the sound?
How about custom seats? Or maybe just cutting out foam to get more clearance for the box?
Is there a box building calculator that will spell everything out? Or someone on here that happens to be a box guru that will share their knowledge? I've got the skills and tools to build my enclosure, but admittedly, the math perplexes me big time. Calculating volume, port size, etc just doesn't really click with me. Ultimately I need to know what size enclosure I can build before I can really decide on how many, if any I'm going to put in the truck.
For box building, if you're building a box for 2 subs instead of just 1, does the needed area increase exponentially, or is the volume calculation different? Especially considering port area and length. I know this would fall under box building ultimately, but I'm trying to figure out how much room I really need.
With box building, do odd shapes cause any sound issues? I don't mean egg shaped, but for example, say a box that looks like the shape of the letter L. Subs mounted on the upright surface and the lower leg for port/volume. I'm not sure if that wording even makes sense, so hopefully someone can answer or at very least try and translate my thought.
