Are These Subs not getting Full Power

I was reading the thread on power, power, power and wondered if I could get much more out of my subs. I have four subs on two dedicated 15 amp circuits. I have two sealed dual Dayton 18 Ultimax boxes and two large vented boxes. I have a total of three Ultimax drivers per circuit and the rest of the gear is also split between the two circuits.

Would a 20 amp or larger breaker really make a difference? I use two I Nuke 6000 DSP for the sealed boxes and two I Nuke 3000 DSP amps for the vented boxes. No problems running at Reference level with great spl, LFE, chest, throat vibrations, ear pressure ect.

If I can get more power/performance out of the subs, what percent increase would you guess for RMS/Peak?

If you're not tripping the circuit you have now, increasing it won't provide more "power" to your system.
Just don't plug a space heater into the same outlet.

Did you really need to quote that entire post in your reply?

If you're not tripping the breaker it's delivering all the power the amp is asking for, once the breaker trips, it's tripped and that's that.
The breaker doesn't limit to 20a, I've seen 60a breakers giving 100a for a short period like a few minutes.

Until you clip or thermal your existing amp, you don't need more power. It gains you nothing.
Breakers are nearly irrelevant by comparison. (Unless you are having breaker issues of course.)

and even if you were...
that doesn't mean that the subs can handle more power!!! (unless you know for sure the coils aren't getting hot and/or the excursion isn't high enough.)


If you are sure, then upgrade the amp.
If the breaker gives you problems, upgrade that too (and the wire).
Rinse and repeat until you are happy or until the woofer dies. LOL!

Then upgrade to beefier woofers.
Then upgrade to beefier amps.
Then upgrade to beefier woofers.
Then upgrade to beefier amps.
When there is no beefier-amps and beefier-woofers left to be had, then start running multiples: 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024 GHorns... Coat the walls with elite woofers and amps! LOL!

I have not tripped a break in a long time. A space heater was on at the time, lol. The clip lights come a lot but the amps never go into protection where the gain knob turns red. My power console will show 1800 watts peak with certain movies like OHF Washington Monument scene. I have two power console so each one has three sub drivers on it. When I had my Chase subs I could hit 200 watts. I can't hit that without boost the bass and then the knob will turn red.

The circuit breaker are a little over a year old. They should be working OK.

OHF is the roughest movie. Tron Legay, WOW, Cloverfireld , Live Die Repeat are all benign on the system

Behringer is the McDonald's of 6 star restaurants.
It's feature loaded and a good bang for buck.
But it isn't the beefiest.

If you need lots more power you'll probably have to start bridging high powered amps.
I would recommend one of these...

Thanks BassThatHz, I think I have enough power. I was just curious and wanted to double check what I thought was correct. I may do a sub build with a 21 or 24 in. driver this summer. Then I may need a more powerful amp.

A bridged CA-18, or RMX-5050 or MA-5050 or CV-5000 are all 5kW into a single 4-ohm load.
Since they are old-school amps they aren't the most efficient (big breaker), but they are likely to make the power they SAY, for days on end.

Maybe pick up one of them and compare it to a decent burst-amplifier, like a FP14k clone...
