Looks like a good time, I've wanted a utility to just enjoy the trails on but haven't sprung for one yet. This is more my idea of fun on one: I've got to buy another quad

I wish I had my cousins old ground pounder Cherokee. That thing got LOUD with ANYTHING in it.

I 2nd the motion.

Damn, first time I have seen this build. Love it, I love the MT 12's, and the whole install is crazy clean. Your the man Steve.

Congrats! There is nothing like them, my kiddos are my world.

some people use different formulas, but this is a commonly used one You need to figure in sub displacement to get the exact final tuning, then stay 4-5hz below that for the SSF. sub displacements would barely change the tuning, and given that his are shallow mounts it might change a couple tenths at most, if that even I missed that post. My bad.

NAPA had a T-55 and T-60 in stock when I needed them.

How do you figure? Looks fine to me, effective box design that's proven.

I'm pleased with the sound of my Boston Acoustics coaxials if you don't want to go components. I'll be getting Memphis PR components in the next few weeks in mine because of the deal I'm getting, but Crescendo also has some nice components for a reasonable price if I remember right.

My buddy and myself always used to hang out with the high school kids when we were in 7th and 8th grade back when NOPI was still in it's prime and EVERYONE wanted a system, when I was 14 I built my first system in my old beater car my Aunt gave me to learn to drive a manual transmission in. By the time I was 16 I had built my first custom box in my first truck, and was wiring all my friends up. In high school I became the go-to guy to get it all wired up, boxes built, equipment suggested, etc. My Junior and Senior years of high school I got into competing and me and my cousin built a Jeep Cherokee with 2 Memphis Mojo 12's off of 4 Directed 2400D's as my first serious setup on the meter, it put out decent numbers. Before SBN in 07 we rebuilt it with 4 Audiobahn Immortal 12's off the same amps. After high school I pretty well had gotten out for 3-4 years before winning a Kicker CVT 10" and Kicker ZX300.1 at a car show. Put it in my Camaro at the time and the bug bit again, went through 3 vehicles since then, and probably 20 setups. Now I do installs and boxes at a local shop, as well as custom boxes on the side. I'm pretty well bored with my truck and what to do with it right now, so I decided to stuff a 15" under the seat and that's when I ended up here.

box volume has almost nothing to do with the amount of port area you need. the woofers, power, and tuning frequency do. I hate it when people generalise and say "you need this much port area for this box volume" no, you don't! I didn't necessarily say it needed it because of box volume, I said that sub needs that much. I also said as a general rule I prefer to stay between 14-16 for normal boxes, not every application obviously some like more, some like less it's just a good baseline. My original post was telling him to get it closer to there then the 8in^2 per cube he had before hand. Skylar is the one who assumed I had no idea what I was doing and used that for every box I build, which is untrue. I've also never seen anyone use 5 in^2 without using aeros without noise, not saying it hasn't been done, I just haven't seen it and can't imagine it.

I can assure you I know what I'm talking about. 5in^2 per cube must have been aeros, otherwise I have not one idea how you didn't get port noise. 12-18 is as a general rule safe area, I prefer to stay between 14-16. If he has BassBoxPro he already has access to all the t/s specs for the sub as they are preloaded in the program. The Solo X will NEED that much port area.

Confused.. It says its tuned to 33.8? So how is there not enough port area? You don't have enough in^2 port per cube. Need 14-16 or so. You may be tuned to that, but the port is too small. Can you please explain this a little more please Open Torres calculator, enter your dimensions, and your port. You'll see it's like 8 in^2 per cube. You're tuning would be correct, but due to the port being too small you'd have issues with port noise and some other things. You need to make your port bigger so it's around 14-16 in^2 per cube. I use Torres for the basic design, then plug it in BassBoxPro for the plotting and fine tuning. Also don't forget to put in all displacements and figure for bracing before you start figuring port or it will change port area and tuning. Also I'd double baffle atleast with that sub.

Not enough port area.

8's. pioneers? 8Zebs or something like that? Not available over here.

8's.

I've used JuiceBox alot, and know several other people that have with no problems. Never checked it on Audacity though.

I'm jealous of those subs. From what you have posted they seem top notch.

For the love of God take it to someone who knows what they are doing. Yellow goes to a constant 12v, red to a 12v source that is only hot when the switch is on, orange (if applicable) goes to something only hot when the lights are cut on, black goes to a good ground, and the blue or blue with white stripe will be your remote wire or power antenna. No other combination, don't try to mix them up from that.

Yepp. Bad ground. Fixed several of these from people locally trying to do it themselves and not getting a good ground, or using a mile long ground wire.

Your ACC wire isn't wired right. Your keeping power when your switch is off, when it's wired properly you should lose current when you cut the switch off on that wire. Your yellow wire should be the only one with power with the switch off. If he's such a good electrician why did he use crimps to begin with instead of soldering and heat shrinking?

There was a guy on here a couple of weeks ago selling coils that would fit the Type R. He had them listed as well as L7's and I think CVX's. Can't remember who it was.

Sub forward, port forward sealed off from the trunk would be my choice. Otherwise #4.
