pioneers recommended enclosures and tuning frequencies are crap.they want you to tune way to high which is good for being loud but less sound quality which is reasonable because those subs are for SPL not SQ.If you plan on entering competitions then follow directions from pioneer.If you like low hard hitting bass then tune 30-35 hz with 1.8-2.2 cu ft. per sub.

Creating jewelry stones of any kind requires little more time and patience, although there are some equipment and material types that will not only ensure your piece lasts, but will also make its creation is much easier. There are some techniques involved, but once mastered, can be applied to a variety of jewelry making projects.

To begin with, you will have to choose their accounts and these, to some extent, inform the choice of the materials used. Heavier grains are more suitable for Tigertail wire (also known as monofilament or nylon coated wire), which is rigid and not requires the use of a needle. It also has the advantage of maintaining its shape. Soft-flex cable is more flexible, is constructed of a greater number of wire strands. Has the advantage over Tigertail in one aspect, because it is so flexible is less likely to develop Kinks, the more rigid Tigertail is prone to do. Tigertail may also require the use of a pair of diagonal wire cutters to achieve color cuts.

Either type of cable can be used in the construction of collar and both need to be completed terminal accounts. These are accounts made of a soft metal that contracts to maintain an account in the position or "close" the open end of the collar. A pair of pliers of pressing is often useful to flatten the accounts and setting them in place. Indeed, the crimp bead is compressed into a form of 'U', which folds on itself to create a round pearl shape.

For intricate designs, a felt of accounts is a useful piece of equipment. The designs are placed on the board before stringing and pad prevents unnecessary movement. This is the first stage of the process. Once you have settled into their design, can then reduce the required length of wire, leaving an extra 12cm (5 inches). Around 40cm-45cm (16-20 inches) in total is a good rule of thumb for a short necklace, but of course if you are creating jewelry as it is recommended to measure precisely the neck of the person you are doing to.

Then attach a crimp account and half of the buckle of his selected wire, leaving the grain embedded in a form of 'U'. The cable should then be pulled back through curly cord, which can be compressed into a ball and keep everything in place.

The cable is now ready to receive the accounts. The closure of accounts and crimp avoid falling wire accounts. However, in the event that you are making a symmetrical piece but not sure of the number of accounts you will use, must leave the hook until you have added the accounts – from central cord and the way they work, adding accounts at each end of the wire until the desired effect achieved.

Once you are satisfied with their work, all that remains is to join the rest of the hook into the open end of the string, using the same process as before.
