I'll be putting 2300 rms to my lvl4, here shortly. It has the lvl5 soft parts and an extra spider, though. I really didnt think that is enough power, to justify getting the XL. I guess Im about to find out!

I set it on the floor. Marvin ran up, sniffed it,... plop'd down, looked at me, and said... yep!

He's not fat. Just husky! I figure if I want to hit some lowwwws, ..I put on the 32hz port. If I want to listen to some rock, or metal, ...screw on the 42hz port. Or maybe it might not work that way, but regaurdless, ..it'll be adjustable.

I was looking at some ports online, ...and decided to try to make one/some, instead. I bought a stick of 4" pvc. It's pretty thick stuff, ..hard to shape. Im mounting the shorter section permanatly inside the box, about 4" off the back, ...and the female threaded coupler will be flush with the face of the box. Im going to make the outer section in a few different lengths. with male couplers, ..so I can play with the tuning. The outer section will be sticking out. I might try some different material, before I stick anything.

It's just a rectangle. I dont really need anything technical. My super ms paint plans above, should be suficient. Im more interested in opinions on the size, and the port.

Anyone?

Does this look ok to anyone?

Im about to start building my box. It's going to be 1.75 net, and tuned to 34hz. This is what Ive come up with.

I would, ..but they didn't give me a sticker, with the sub. I wouldve thought they would have sent one. Just a dust cap. Im sure you could put it on just about any sub. Keep in mind, ...I dont have a Lvl 5. Its an upgraded Lvl 4. So, ..since Im putting 2300 watts to it, ...thats why a 1.75 cf box would be good? I still cant figure out the port. Would one 3" port be good? Because it would only need to be 7.2" long. Or should I have a 4" sticking way out of the box?

Im @ 2.5 cubes on my lvl 5 12". Its much louder than the 1.6 CF box I made later to test. Both around 19 cubes of port per. Thats what I dont understand. The guy at DC said that 2.5cf box is too big. Why do they say thats too big, ..and you say yours is much louder in a bigger box? Everyone I talk to tells me something different. Is there any way to learn how this stuff works? I only want to build this one time. Im also trying to figure out what size port I should use. If I use a round 4" port, it needs to be 13.8" long. My box will only be about 10" deep. So, the port would have to stick out towards the rear of the car, quite a bit, ...depending on how close it is to the front of the box. If I use a 3" port, it only needs to be 7.2" long. BUT, ...a 3" port might be too small. I really dont know which to go with.

This is the car. I called DC, ..and the person I spoke to recommended 1.75 net. And, ..use a 4" round port. I read somewhere that a flared port is more efficient than a straight one. So, ..Im starting to look for a aero port. Thing is, ..my trunk space is very limited. The port will have to stick out of the box.

See, ..I read that it should be somewhere around 1.5. When I mentioned that to a couple different people, they said that thats bs, ..its way too small. I talked to a guy running a 3.5 cu box, for one 12"! According to this guy, ..the bigger the box, the louder it will be. I dont understand the concept. I cant find any info, ..on how it works, ..or at least the basics of it. The car its going in is a SC300 Lexus. The gas tank is in the trunk. So, it will be rear facing. Im using a DD M2a for it. 1 ohm.

It took a little longer than expected, ...but it came today! Lvl 4 12", lvl 5 soft parts, extra spider, inverted dust cap. Now, ..I still have to figure out what type of enclosure to build. I cant seem to find any good info on it, ..and asking doesnt get answers, either. Im leaning towards 2.5cu ft net, ..with two 4" pvc ports, ...somehow tuned to 34htz. And some other goodies, going in the car!

Pics from today.

4 months? Why? I placed my order for just 1 12" sub, ..and they said tun around is only 3-4 days. Orders that are placed now have a turn around time of 3-5 days. Until about 3 weeks ago they motors had been out of stock since the first of march. Ohhhh, ..I see. Looks like it worked out great for me!
