nah bro............1501d will run half ohm for about 7 minutes before it freaks out from heat and other sorts of not goodness.....i know this from expirence....
now i ran 2 1501d's and that was pretty sweet
then i ran a kx 2500.1 which in a direct swap out was louder than the 2 1501ds ( also an zx2500.1 direct swap was louder than 2 1501ds in another CA.coms dudes setup)
get the kx 2500.1, itll be worth it...... 1 ohm daily stable
according to vetkilla, his (now mine) kx 2500.1 performed better @ 2ohm then his 20.1 did @ .5ohm....not to mention they are pretty efficent (more so then the 20.1 at least)......granted this was in the enviroment of vetkillas car and everything differs per car/install yadda yadda yadda.....but between the kicker being efficent, beastly @ 2ohms, and 1 ohm stable daily...i was convinced....PM vetkilla, he might be able to get u a good price, he has his connects being the FL amp man
