I am getting distortion at all levles of volume from 4 different lanzar maxp124d subwoofers. no matter how i wire them or what style box i've tried i get the same results.

have diagram of any sort?

Does the enclosure volume and style/type match the sub requirements? Are the subs wired correctly? I've seen lots of marking on the wrong terminal. Try switching one of the subs from pos to neg and neg to positive. It will be dramatic and very noticable if that's all it is.
Is your cutoff frequency correct for the sub? Make sure they're not getting full spectrum frequency. Are the Subs physically hitting any part of the enclosure at any point in the excursion? Are they screwed securely to the enclosure? Is the sub surround intact and smooth through the full extcurion? Is the amp ok? Got enough current throughout the system? Battery, Capacitor, Wiring, fuses, speaker wire etc. Bigger is better but always the correct fuse rating.
Signal from the head unit? Proper preamp wiring?

If you have a spec sheet as far as volume and any trunk dimensions I can design exactly what you are seeking.

Need to know the vehicle first.

Here are the specs for your speaker.

Dual 4 Ohms Nom. Impedance

Fs: 40Hz, Qms:5.0, Qes: 0.90, Qts: 0.75, SPL: 84(dB), Vas: 5.204(Cuft)

That should help you design a good box.

The eight terminals are actually 4 with double slide ons for each. Each side has a + (positive)
and a - (negative) with 2 connectors at each connection point.
It is a dual voice coil thus 2 sets of inputs.
If you have a 4 ohm amplifier then you are ready to go with a left to one side's terminal and a right amp output going to the other. If you have 2 speakers this can get wild because you can run them in parallel
or series and reduce the impedance to 2 ohms if your amp is 2 ohm stable. If not-dont do it!
You will burn the amp up. See #58 on the right sidebar of this site. It will teach you how to get the most
from your setup. Bookmark the site. It has every kind of knowledge you need for audio or electricity.
Look for the DVC (dual voice coil) info.
"The image below shows the DVC speaker wired to both channels of a stereo amplifier. Each channel of the amplifier drives a 4 ohm load. " This looks like what you have to do.

There are 4 connectors on each side of the Problem with the Lanzar 15'' 2000 Watt Dual Voice Coil Subwoofer Driver for Small Enclosures Car Speaker. how do i wire it so i can put the sub in the box so i can connect it to my amp?

either your pushing your subs to hard and its creating a backsurge of resistance, or the spider wires are touching the frame causing them to foul out. It honestly sounds like you are trying to run too low of an impedance subwoofer, and your amp infinitys clip to keep from distorting, distortion played through a subwoofer at high volumes is damaging to the subwoofer and the amplifier. reduce your gain, and check your wires, the clipping should stop, a good rule of thumb always have an amplifer that will do rms what your speakers can do peak, so that way you can keep the amp turned up only 1/4 of the way and be pushing your subs at a decent rms volume with 0 distortion.

The quickest way to tell the woofers are good or still hooked up... you need a multimeter set to ohms. test each speaker and make sure you get a reading of 2, 4 or 8 ohms. ifs its a prefab box, probably 4 ohms each but still depends on make. Make sure the speakers have good connection inside and out. Make sure amp wiring is in good condition too.

take a look there and it should give you everything you need and show you the different options for the different ohm loads. Remember... don't go below 4 ohms on those. Above is ok, below is not.

Remember that driving a load with an underpowered amp will probably cause more problems than having a more powerful amp that is not running flat out. 200-300W amp would be ok, but I would suggest going for the biggest you can afford. If you crank up the volume on the smaller amp you will probably get a fair amount of distortion, which may actually damage the speakers. A larger amp will not give as much distortion for the same loudness/volume and give better control of the speakers for a tighter bass..
