It is a theoretical 5-6db gain. If you do it properly it could be more, if you do it wrong (or ghetto or whatever) you could have no gain. If you put it in the same box off the RMS that the sub is rated for, you should get about 6db of gain. Thats all just numbers though, it's different in the real world. I would expect 6db though. You could buy cheaper stuff and have more cone area etc but it would probably be worse because it's cheap stuff. You could also build your box like thorshammer and his 10"s. build a box with sub and port forward and seal off the trunk, you would need to fold your seats down though. You could also build a bandpass (tricky to design, but there are some on here that can) and port through the rear deck, you wouldn't see your sub though (unless you put a perspex side on the box (not cheap to do). I would say your best bet is to get the stuff you have planned for, and build a new box, or if your current box is already awesome, then just upgrade the sub and amp.

If the 2200 has a higher sensitivity than the copper one, then go for it. Otherwise there will not be a super difference between the copper and the aluminum coil ones. 6db gain is great, if you built a new box, you might be able to get more.

You need 5 times more power for it to sound 3 times louder. 3 times the RMS will only increase by 6db. say you gave your alpine 3 times more power (if it didn't roast with the power) it would be 1.5 times louder. If you change subs to one with a lower sensitivity and keep the same power it will be quieter, change to one with a better sensitivity it will be louder. You though are upgrading both. I don't know what the sensitivities are for AQ and the alpine, but lets say they are both 90db/1w/1m therefore in a box (they are probably measured in a sealed one) of the same size for both off 1w, they will theoretically be equal. but if you raise the power to the highest RMS for both, the AQ will be louder, as it can take 3 times more power. So in this theoretical sealed box that they are measured in, the alpine would do 117db, and the AQ 122db. This is in a crappy box with identical sensitivities. Therefore you should get at least 6db

^hope this helps BTW, I'd go for 0g if I was you.

^I have answered some up here

I would definitely go with the AQ's. Round>square. What amp you get depends on how much money you have maybe a sundown if you can Big 3, better battery. If there is voltage drop to below battery voltage, then a second battery, or if you want, an alternator. But a second battery would be enough.

Lots of weather stripping, tapeing the latch could help too, then it won't wear down, which would cause more flex.

nice! how many watts is that running on? might need some deadening too

awesome! looks great! Any chance of some vids of it?

Yep I can help you design it, 1 15" alpine type R? I think I can do that . PM me how much room you have in your trunk and I'll get onto it ASAP

everyone on here would recommend ported, as long as is a "nice box " , I can help you design it and so can many others on here . Don't be so hard on yourself, everyone needs to start somewhere, I'm sure you will learn a lot on this website, I know I did, and I'm still learning, there is so much to know and thet knowledge just keeps growing

medium density fiberboard. The wood that is pretty much compressed sawdust, very good for making subwoofer boxes, used by most people on here. It you build a ported box, you will have to use a calculator (there is one on this site, made by torres, a download link is on his page) to work out what frequency the box will be tuned to, I would suggest around 35hz, the port should also be between 12-14 square inches per cubic foot of the box, all this is in the help section of torres's calculator. maybe make the box 3 cubic feet. If you need more help with enclosures, then have a search around or ask some people on here, we're all glad to help

correct amount of cubic feet, good sized port, nice tuning frequency. Made out of MDF, no leaks (caulked well, like your other box) mostly tuning and size though, thats what people mean by "nice box"

don't buy pre fab boxes, they are terrible, build a nice box You don't have to buy batteries, you can upgrade alternators etc, but you don't need to, it's better if you do though.

no problem in giving them more, it will allow for box rise etc.

If you do it right, good box+good power, it will sound louder because you have more cone area.

you can either bend the tape it, bend it, or spend money on new RCAs. What do you mean they don't fit in, will they not go all the way in? If not, then try you might need to get new RCAs. since it goes in the other sockets though it must be a problem with the deck. The reason it doesn't work on the other one is because it is a input for the H/U and you need to use the output (which it doesn't fit into) EDIT: swap the RCAs around so the end in the amp is in the H/U and see if the other end will fit in the amp or not.

a wall with 2 15"s? but otherwise, the 12"s sealed off from the trunk, port through rear deck.

Don't you know? It means that it's loud! Has the O/P fixed the problem?

If you turn any amplifier up too much, it clips, which can damage speakers, and it sounds hideous. You know the guys who drive around with their 6 by 9s at max and it sounds like chgzggzgzg chgzgzzgz chgzgzgz, like that!

Unless he's tuning it up to max .

It could be the head units amp distorting. What does it have to be turned up to for it to distort? If not, your fronts can't handle it. upgrade time!

But thats my mommy . lol j/k O/P nice sub

Oh right, the one with 32 10"s, there's not much left for him to do, he has done pretty much every configuration!
