When looking at SPL, the biggest woofer you can physically put in is what you need. Also the cone material should be extremely stiff to the point you can’t distort the cone with the pressure of your finger pushing on it. Then you need as much wattage as you can afford as well as the electrical upgrades to the charging system to keep up with the current demand. If you look at the competition you will find they have spent several thousand dollars to hit high SPL. Hope this helps.

SPL
If your goal is sheer output, and you don’t mind sacrificing decent sound to accomplish that goal, then you’re going to want to look for subs that are SPL optimized. What you want to look for is a sub that has high excursion, large cone area, and high power handling. Don’t assume that just because a sub has a massive stack of magnets and a big fat surround that it can get loud. There are many subs out there that look the part, that don’t act the part. If you intend to build a massive SPL rig, then you’ll want to use a large quantity of smaller subs, say 8 10” subs instead of 2 18” subs. This lets you maximize your cone area for the space that you have to work with. 8 10” subs and 2 18” subs will both take up a mounting area of roughly 20×40”. The 2 18” subs will have approximately 500 in^2 of moving cone area, where 8 10” subs will have approximately 600 in^2. Likewise, since ported enclosures are much larger than sealed enclosures for a given sub, your big SPL vehicles that are full of subs usually use sealed enclosures so that they can fit more subs into a given area. If you’re only going to use a limited number of subs, you can get more maximum output out of that given quantity by using a ported enclosure, but that will be explained later on. Quite often a sub designed for SPL will have a fairly high Qts and/or Vas, and the suggested enclosure will be smaller than what an “optimum” enclosure would be. This results in a very high Q alignment that increases output over a narrow frequency range, at the expense of a smooth frequency response that you’d want from an SQ subwoofer. There are a lot more variables involved with an SPL setup than a few sub parameters, so it’s a good idea to spend some time talking to various people (who know what they’re talking about) about their SPL experiences, as well as taking in a soundoff or two in your local area. Watch the DB drags and see how people are scoring, but pay particular attention to their whole setup, not just the brand of sub. What box are they using, what size is the box, what is the port tuned to if it’s ported, what amp, what kind of car, etc. All of that will effect the sub’s output abilities.
