Could someone clarify something for me?

Ok, here it goes.

How can an amp that had 2-30 amp fuses in it be rated to do 850rms @2ohm?

The amp in question is a kenwood 9102d. Cea 2006 compliant.

rated 500rms at 4ohm. that figure seems right, cause 60amps x 14.4 volts = 864, and factering on efficientcy of around 65%(figured around here) gives slightly more than 500 watts.

Do amps not use anymore power the lower the ohm load. I have tried to google an answer, but have come up empty.

Could anyone help me out and answer this for me, or even better explain it to me?

thanks.

it iwll prolly run 850 max power. the spec is prolly for max power at 2 ohms

Nope it is listed as 850 rms on the kenwood website.

I though CEA compliant means the amp has to do what is listed, and it WON'T be max ratings. Kinda odd on the fusing though.

That is what i thought as well. Main reason why i am asking this question.

850/14.4= 59.02 seems right to me.

lower the resistance the more current will travel getting the most power from the amp.

like a toilet the bigger the toilet and piping the easier it is for the sh!t to pass thru without and y draw back.

so in ur theory the amp is 100% efficiant? cool, wheres this amp? I want one.

my bad everyone, i didnt see the CEA complaint. i miss read sorry, about the false info on my part.

The amp will make its power. Fuses don't blow instantly and you won't pull the 120A required to cause those fuses to "fast blow." With music it will comfortably make power without drawing signifcantly over 60A for a long enough period of time to blow the fuses either. Now if you want this amp for SPL comps, you might want to get a different amp.

dont want any amp for spl reasons. It a friend of mines that is getting an estimate to repair right now. if it too much for him to shell out i may just pick it up and use it my self on my maw 15".

better than the sony "900rms" amp i have now. most likely 300 or so rms.

might do 900rms gain cranked, 4 volt hu preout turned up all the way. with who knows how much thd.

i only got it fixed because the $100 to fix it was less than buying another amp 300rms or higher with warrenty.
