There may be! I'm probably going to get the JL Audio DSP which I can get from the US for a little under $300 delivered - looks pretty good. There is a SoundStream DSP which is much cheaper but weighs more so costs a lot more to ship, and anyway looks like it is much less effective than the JL Audio.

I think I'm going to end up with a Kenwood 8" sub as a direct replacement for the existing free-air sub, but maybe there are some more musical subs out there that I don't know about. I have not found another sub so far that works well in a free air environment, and I really don't want to go the path of an enclosure at this stage. I plan to line the boot with mass loaded vinyl to cut out road surface noise and improve the efficiency of the sub.
