Found this review. this is just part of it.
The 13W7 is an odd sized woofer- While most manufacturers offer 10 and 12, then 15 inch, JL chose a 13 because it fits in a more reasonably sized enclosure than a 15 just on diameter alone. (Ironically, enclosure size for all the W7's is NOT exactly reasonable, but we'll get to that later). The 13W7 is rated to play optimally at about 1000 watts of continuous (RMS) power. There's all types of power out there, from horrendous to fabulous- Watts come in all shapes and sizes. Having been involved in mobile audio for the majority of my life, and now an owner of a custom install shop, I've seen it done many MANY ways- however I'm not going to bother citing failure-stories of an idiot who tried putting a pyramid amp on a serious sub. In the case of THIS sub, a JL 1000/1, Van Gogh 1600.2 and a PPI PCX2400. All three amps are very good in terms of sound quality- and I'm sure if you're reading this you may already have an opinion on which is best- however I'll say from my own experience, the Van Gogh is absolutely the most superb sound-quality oriented, yet still punchy AND musical sounding amp line I've seen in a LONG, LONG time. All thee amps brought out different attributes in the woofer, yet the overall theme remained the same- keep reading, we'll get there.
