The sub is actually a VERY important part of the equation. A DD, no series, will get as low as a similar sized TC Sounds, Soundsplinter, TREO, W7,or similar SQ/SQL sub. You could put any of these in a small-ish sealed box and play lower frequencys than most MUSIC will ever produceThe subs are only a small part of the equation. If you want low bass it starts with build quality of the box. If you did it right I would imagine a huge box tuned properly with 18s or 22s would go very low. Still you need electrical to back this up. Every vehicle is different too. Some can get low and some can get loud.
DD FTW to me but I'm biased, like every other audio enthusiast. Use your ears and choose.

playing below tuning and playing without a subsonic filter are two very different componentsYou risk damaging the sub by playing it without a subsonic filter.
