0.5 ohms?

[SPL_DC2 10+ year member]

i got a hifonics mono class d amp (Brutus 2005) and i was wondering if it was safe to run this amp at 0.5 ohm for burp purposes only. i found out the XX series could handle down to .5 (only burps) and it'll be fine.

It'll shut off mre than likely. But you could try.

Give it a shot. What's the worst that can happen? Buy a new amp?

As long as your electrical is up to the task it will probably survive burps....what upgrades do you have?

i got an optimal battery as the only upgrade. if it's not able to withstand .5 ohms, will it just go into protect?

Hopefully.

alright here the deal. i just spoke to an authorized hifonics technician and he said that i very well could! just as long as i have a top end battery (optimal) and that i need wo have at least two runs of zero gauge wires going back to the amp! i'll keep you guyz posted on how i do! thanks for the replies guyz!

i can't imagine two runs of 0 gauge are necessary

if it's rated 2000rms, @ .5 ohms after imp. rise, the MOST you'll see is 3500w or less, which is still fine through 0 gauge.

A battery alone's not going to supply that, tho.

yeah on paper it supplies enough. but 2 runs would supply twice as much and help with the voltage drop during burps

how about 1 huge run of welding wire with a kenetic battery (drop the optimal yellow top)? what size fuze will i need for this?
