Can a Rockford fosgate t2500-1bd run at 0.5 ohms with every day use

Nope

Why do you want to run at .5 ohms?

if you have to ask, no.

Try it and find out, thats really the best advice since its not rated to go that low. It may work for a year, months, days, minutes, seconds or not power up at all and go straight into protect.

Wired down that low will most likely do that amp in. The first hard bass note will throw it into protect, or worse.

Why would you want to run at .5ohm daily?

I was told the circuitry will not even allow it..... From Rockford

lmfao stupid question

Yeah it will work and fry as well trust me.
