Current setup is two sealed 15 inch titanic mk IIIs powered by one epx4000, and two sealed uxl-18s powered by another epx4000. Now I know from looking at tests done on amplifiers, that most don't seem to come close to their rated rms output and know that both my uxl-18s are definitely being under utilized, my titanics are probably also.


At first I was thinking I could buy up 2 more epx4000 amps for only $600 and have each sub I have bridged to their own epx4000. I'm sure a bridged epx4000 would be able to push my titanics to their max with still some headroom left but doubt even a bridged epx4000 could fully utilize an uxl-18 as I've heard the 1,200rms rating on those is quite conservative. I initially thought about getting a single Crest CA18 amp which should definitely be able to get the uxl-18 to max clean output and then some but the cheapest I could find one of those is around $1,700, for that you could buy almost six epx4000 amps. Price to performance ratio is what has me thinking on a better solution. So what amp or amps would be a good solution, one that could drive a uxl-18 to its full potential while not breaking the bank.

I would put your 4000s on your titanics and pick up a nu6000 for your 18s

"4000" watts bridged isn't enough to fully utilize the uxl-18? what do you estimate a bridged epx4000 nets bridged?

[q120 volt me="doublewing11" url="/t/1525152/best-amplifier-s-for-my-2-uxl-18-price-to-performance-ratio-has-me-second-guessing#post_24551434"]Peavey ipr2 7500......but will need 20 amp circuit[/quote]


Will look into that one thanks. Circuits definitely no issue, i wired my own two 20amp outlets, each outlet with their own 20 amp circuit with 12awg wire running only roughly 25 feet from breaker to outlet. If I needed to add another it wouldn't be a problem as my home theater room is in very close proximity to my breaker box.

There's a big difference on what they say their amp can handle vs real world use. With the way a lot of these companies come up with these output numbers, they test it specific way that really doesn't mean much in real world usage. I've used one of my bridged epx4000 on my uxl before and the amp would go into protect mode with heavy bass far too easy, I could tell my sub was not bottoming out, the amp would just go into protect for a couple seconds then back on.

the cerwin vega cv5000 is a copy of the ca18. it looks to be pretty good and a few folks around here are running them. street price is about $800 iirc.

approximately 1900 or so. it is quite similar iirc to the ep4000 which is the same(?) as the ep2500, but with a smps in place of the toroidal coil.

Thanks. And more to my own case, what does a inuke3000 yield bridged?

About 2200 watts

That one looks like my best bet. I noticed according to the manual for the cv-5000 that at 1/3 power at 4ohm it uses 26.9amps, at full rated power it'll use 56.4amps... Should I run another circuit for this amp? Right now I have one epx to each of the 20 amp circuits I have now. Should I maybe run a 8awg wire with a 40amp breaker to put the cv-5000 on?

Or if the amp is easily switchable I can run a 240 volt 20 amp circuit. Any advice. Cause I hear people do fine with a dedicated 120 volt 20 amp circuit but when pushing them are able to trip the breaker, I'd prefer not to have any trips ever and nonexistent voltage drops.

Send Gorilla83 or ChopShop a PM. They have both used that CV5000 and can tell you what they had it on

So a 3000 watt inuke yields 2200 watts, but a 4000 watt europower amp only yields 1900 watts? Interesting. Why is the inuke so much more efficient?

I can trip my breaker on a dedicated 20 amp line but that's only when I clip the hell out of the CV running 8 18" SI's. I have never tripped a breaker once when staying below clipping.

Amplifier power rating have to be qualified to be compared: In other words the circumstances under which those numbers were obtained.

Test conditions can be manipulated to produce BIG numbers that sell amps, especially Pro Amps.

I've got 2 cv 5000.I run them on 20 amp circuits each has there own .I run them 4 ohm bridged I have ran them for 2 hrs listening to music red lights consistently flashing. And I haven't tripped a breaker yet. Plus they don't even get warm.

I have ordered two UXL18s. After searching this forum and Google I decided to go with the Inuke 6000dsp. Bang for the buck, can't be beat.


Perhaps this will help.

This has been my experience too. The red lights can flash with no problems at all, if it's solid red for very long then the breaker trips.


Also it runs cool even when tripping the breaker.

Despite the value of amps like the inuke, I've gotten hesitant on buying any amps that I want a lot of power out of but only require a 15 amp outlet. Like for example, if you wanted something like a true 1,500 watt RMS X 2 amplifier, no way is a 15 amp circuit going to continuously give you that much power. Makes me wonder about other amps too though and why one has similar ratings but require different amperage outlets. Like the cv-5000 needs a 20 amp outlet and supposedly produces close to if not the same amount of power as a crest ca-18 but the ca-18 requires and uses a 30 amp plug.
