b00ty bass is like i have, its a good mix of sq and spl, however i wish i had some more SPL, i would say give the SA's a go they impressed me every time i have heard one so far.
probably but i have an odd love for sundown, i would say find some one local that has one in a good setup and give it a lission, there under rated on the power they can take, there cheep as dirt to recone if you break one. my other choice if you had a 1500-2k amp would be the FI SSD's but you can easily push 1k to the SA's on a clean signal and they will beat away. there also probably the cheapest on the list next to the type R's, but i have not priced the whole list so you can call bull on me. theres a kid on caco who just got 1 12" SA on a crappy infinity amp ~800 watts iirc and he has some car flex. not bad for his first setup. i have seen and heard the DD's they didn't really impress me all that much, may have been the set up they where in, maybe i was expecting more out of 4 18"s.....
you can push more then that to them, easily 1k would be more like there true rms. but the rms is low enough that there easy to power but beastly enough to take the extra.
