Just be advised most amps out there are not .5 ohm stable. Usually they are only the higher end amps. The closer you get to 0 ohm...it's considered a direct short. The amp will be so hot you could fry an egg on it. I have seen some amps that are 1/4 ohm stable but they run about $4000.00 I know some amps claim they are .5 ohm, but if the price of them is too good to be true, I would wonder.
As per your question, I don't think the amp would work. Unless the amp says it could run at .5 ohm, don't do it. Besides isn't 2000 watts enough
refer to bold. if you go below 1 ohm and arent paying a small fortune on your setup and you're not Db draggin or too rich with nothing better to do you're nuts.
and I pray that you're gonna get a setup for your highs to match all that bass. other wise you're going to have 1 super craptacular boom and no music. Unless you like to only hear bass? IMO 2K watts is way too much for most people. you'll rarely if ever have it to full power and whe you do not for long. also with that kinda draw better plan to set aside $$ for a better high performing Alternator, cap and other accessories like that.
just want you to have a better idea of what you're getting into since it doesnt seem like you fully understand the way these things work
