usaci rules

[slim j 10+ year member]

My friend and I have an argument concerning the interpretation of usaci rules. He says that it matters what the subs are wired to (ie 1 ohm) but I say according to the rulebook, it only matters what your amp does at 4 ohms. Here are the rules

“A car audio system’s total wattage shall be determined by the highest manufacturer rated output divided by the proper number to ascertain the 4 ohm power output, or the manufacturer’s 4 ohm rating, whichever is higher. If any amplifiers rating cannot be determined, that amplifier will be moved to the highest power class in that division until such time as a rating can be determined. USACI reserves the right to independently test any amplifier to determine the true RMS power rating and reclassify that amplifier as needed.”

Who is correct? If I had an amp that did 400 @ 4 ohms and 1500 @ 1 ohm would I be in 301-900 or 901- 1800?

Rules are based off the 4ohm rateing.

What is the difference between streetmax and super street?

Street max? super street? I think you are talking about dbdrag. Usaci is only

you are correct...I am just trying to think about building a system where I could compete in both.

Have you competed before?

Your only problem is that USACi is based off power and DB Drag is based off of cone area.

Yeah that's what it looks like...I will either be in street max 1-2 and 301-900. Both look like tough classes. I will need to hit 160 or so to be "world" competitive.

never competed before but it looks like something I might want to get into.
