I am now using an inuke 3000dsp to power 2 subs in the back of my room and have the CV 5000 powering the other 6 in the front of my room. I was considering selling the CV 5000 and buying the inuke 6000dsp. I figured I'd have less chance of tripping a breaker (very rare as is, but still it would be nice to never trip it) and I love the dynamic eq function on the inuke dsp. Plus, at the price the inukes are at right now I could actually make money on the whole thing.
Running an inuke 6000 on my up front 6 subs would be = to running an inuke 3000 in bridge mode on 3 of my subs, at least that's how I understand it.
I have the SI 18 D4's so in both configurations (CV 5000 and inuke 3000) the amp would get a 3 ohm load since there is 3 drivers.
Ok, so today I level matched the inuke 3000dsp and CV using frequency sweeps and matching them up. I made sure to use the same 3 subs for both sweeps and for the comparison. I wanted to see which amp would clip first.
I used the song Bass I Love You since it has strong output at 17hz on the long extended note and also that single single digit hit.
Anyway, with 3 of the subs running on the CV I got the MV up to 8.5 over reference with the sub trim pretty hot. At 9 over reference on the MV the clip light would blink on the quick hitting note below 10hz.
I tried the same thing on the inuke. For both of these tests I was in the room where my amps are and it was like a jet engine was taking off with how loud the inukes fan was getting. Again I inched up the volume until I saw the first red blinking. I came back out to the HT room and the MV was at 7 over reference.
I went back and forth 2 more times with each amp to make sure I got it right, and I got the same results. The inuke clip light blinked 2 db's before the CV every time.
So, I guess I'll hang on to the CV. 2 db's isn't a ton but my test was just on 3 of the 6 up front subs so I would actually lose 4 db's right? No good.
I should be getting 900 ish watts from the CV since there are now only 3 drivers instead of 4 per channel (3 ohm load, the CV puts out 2500 per channel in 2 ohms) but shouldn't I be getting more from the inuke in 3 ohms since I would get over 700 watts in 4 ohms?
Could be the inuke doesn't like 3 ohms? That would make sense since it's only rated for 4 ohms bridged. It never did shut down though, and I let most of the song play at those very loud volumes (speakers off).
