PPI PC2350 @ 3ohms

FireII · 25th May 2010, 12:39 AM

Has anyone ever ran into any problems running a pc2350 at 3ohms mono, a JL 12w7 in particular?

I..... would not do it. That amp is worth way too much to risk running at lower than optimum. I'm not sure if its the same but the art .2 series actually dropped power output if you ran them at lower than recommended loads. Not sure if the 2350 uses the same AM2 circuitry though. I had a pc2350, it was an excellent amplifier.

I ran into a 2350 just a few minutes ago, I've always waned one so I ended up buying it, then I was like..... "damn, what am I going to do with it"? Stack it with the rest of them, I guess =)

Run your components, it will sound ridiculously clean. Or you could just donate it to me

The PC4100 and PC450 are doing that well =) I might just switch the W7 out to the IDMAX.....

Although from looking at the nominal impedanceon both subs, the w7 only gets .4ohms lower than the IDMAX..... Hmmmm.... I did just get off of the phone with a friend of a friend who worked for PPI in Arizona, he says it should run without a problem.

So is the idmax 3.4 and the w7 3? I would think 3.7-3.8 and up would be ok adding in wire resistance but well who knows, maybe wire resistance will be enough to keep it safe.

THe nominal impedance for the w7 is 2.47ohms and for the IDMAX-D2 ran in series is 2.8ohms. I would like to get an impedance curve for both but I can't seem to find one for either.

I'm waiting on Perry to chime in with, "PPI rated the amp at 4ohms mono for a reason".
