idk what you guys are on...but the old hifonics amps pre-maxxsonic were incredible..
the Hercules, colossus and Goliath were some of the greatest amps of their time...
so before you ride the sundown bandwagon, think a little.
sundown has great products i will agree, but hifonics you cant deny their older products.
in addition, kicker subs are pretty decent for the price.
yes their not the best, but they do what their name says, kick.
their amps are extremely stout.
one of my first amps, Kicker zx750.1,
lasted forever, and took multiple beatings with voltage drops and still was great.
