Can you tell me which size of boxes I need for my two subwoofer AW1006T My amplifiers is A2300HCT. I only want the plan and the size of boxes that I need. Thanks!
What kind of car are you putting this in to? The amount of air space in the vehicle will determine which type of box is ideal for you. Say they are in a band pass box and that sounds good in a hatchback may not necessarily sound good in a sedan though. What kind of car are you putting this in to?

Wow you are in luck, I used to be an Audiobahn dealer. Designing sub enclosures is my fulltime job. So here you go.-
If you are looking for sound that is very smooth, and has a very low end shaking everything setting off car alarms. You will need a PORTED BOX that is 3 CUBIC FEET FOR EACH SUB WOOFER. It actually calls for 2.7cu.ft but after you add speaker displacement and bracing it should be at least 3 cu.ft. The port can be either round or square made of plastic or 3/4" wood respectively. My port suggestions are dependent on how much space you have. The shortest round port might make some noise (too much pressure!). So think about that first. Anyway the short port is 3" diameter and 15.5" long. The longer port is 4" in diameter and 28.25" long. The rectangular wood port can also be either (port measurements are inside diamensions) 3" w x 3" w x 18.5" long (short port) or 2 w x 10.5 h x 48' long. The second longer wood port is recommended most but will take up a lot of space. The fact that you have to subtract the port volume from the box makes for space issues in cars. Also the second wood port sounds better and won't make much wind noise, but takes up .75 cu.ft worth of space. So in plain english your box will have to have an internal volume of 3.75cu.ft. An example of this could be made of 3/4" thick MDF, have 1" x 1" internal bracing and measure (box dimensions are external and assumes the use of 3/4" MDF) 12" h x 18" w x 30" deep. The port is an integral part of the box fitting inside. I'm sorry I can't provide any drawings to make things easier. Now this box size is one that I ran through a computer program I use. So it is not the same as the manufactures recommendations. I will list those as well.
The second box is an example using a round short port and also uses 3/4" MDF, 1 x 1" bracing, the 3" dia x 15.5" long port, and measures 12" x 18" x 24" externally.
If space is an issue try checking out the information below. -I got it from Audiobahn-
If for some reason it doesn't show up or you need assistance let me know. Good luck and enjoy your new setup-I'm sure you'll be happily disturbing the peace soon!

Do some research on the model of subwoofer and find the recommended box size, subwoofers need the correct box size to work to its full potential, and size in meaning the volume of space inside the box so if you cant fit your box in your trunk cut it down to the size you need but make it bigger as much as you took of if you have more room say in night for eg.i hope the heaps otherwise there is so much online about sub enclosures.
The car falling apart is a NO. But if you want a lot of Boomy Bass, then make sure to make a ported box for your sub woofer and give it the power it needs. If i knew the exact model i would tell you the size of box and amount of power you would need to amplify it.

On the amplifier side, I will need the wattage, and frequency of the speaker to tell you what amp you will need.
Subwoofers differ in only one way. You get an "Open Air" and a "Closed air" subwoofer, That being said, you'll have to check on your magnet which one you have to make the boxes for that sub. If it is an "Open air" Subwoofer, you should see a "wire mesh" or "grid" in the centre, at the back of the magnet. If it is a "Closed air", the magnet will be solid with no hole whatsoever.
If it is a "Open air" sub, your boxes should be sealed with silicone, and no ports are to be cut in your box.
With "Closed air" subs, you should have 2 ports below your sub and the port sizes should be around 50mm in diameter. You should start with a 100mm long piece in the one box and add 50mm increments to "tune" the port up to 250mm, depending on the frequency of bass you require.
On a 15 inch subwoofer ranging between 80Hz and 120Hz, the box size required should be around 27 liters, meaning that you will end up with a box of 16 inches high, x 16 inches wide, x 16 inches deep. Or 320mm high, x 320mm wide, x 320mm deep. Enjoy!
Dual 4 ohm subwoofers can only be wired @ 1 ohm, 4 ohm or 8 ohm.
2 ohm mono load is not possible.
You will need to use (1) subwoofer to get the 1000W out of the amp.
Wire both positives on one sub to + on amplifier and both - on the same sub to - on amplifier to give the amplifier a 2 Ohm load.
Add a second amplifier, or buy an amplifier that is 1 ohm mono stable.
You can wire both to the amplifier at 4 ohms 600W, but they will share the power and only see 300W ea.
alot of times its not just the amp that gives you better sounding bass.. A lot has a to do with a few other factors as well.. first off your subwoofer.. the bigger the subwoofer the deeper the bass. Some woofers exturde, or flex differently depending on the quality and structure of the woofer.. 2nd is gonna be the sub box. different size boxes will give your sub diff. depths of bass. ... general idea is the bigger the box deeper the bass. But if your woofer is not supplied enough power a big box is useless.
With that size amp your best bet is too run a single woofer. Probably a 10inch woofer would sound the best.. but it in.75cub inch. sealed box.. should sound great.
Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up normally, the wiring and speakers need to be checked. If it still shuts down, the amp likely has blown output transistors.
What kind of car are you putting this in to? The amount of air space in the vehicle will determine which type of box is ideal for you. Say they are in a band pass box and that sounds good in a hatchback may not necessarily sound good in a sedan though.
