Hi, I have some old loudspeakers (2 x Subs & 2 x Tops) in storage that I haven't used in years. I need some amps/gear to get them going. In my mind my ideal setup is DJ Controller > Mixer > EQ > Crossover > Amps > Loudspeakers. But I'm on a budget and It's something I won't get to use much 🙁. So my idea is if I get Behringer NX-D series amps, these have a built in eq/crossover. So what I'm wondering is could my signal chain be reduced to > DJ Controller > split main out somehow? > seperate signal to amp for Subs and amp for Tops and then do eq/crossover settings on the amps (the amps don't appear to have thru ports so that's why I think I need to split the main out signal)? I'm guessing there's something simple I could buy to split/double a xlr main output from the DJ controller (that wont degrade the signal of course)? Or is there a cable that splits an amp input into a thru port? Will this work, any problems with this or alternative ideas?
Cheers!
Cheers!
Yeah this easy and you don't need any splitters, simply use one amp for each channel with output A going to the sub and B to the top.

This also allows you to keep the speaker cable runs nice and short, and you've got built-in redundancy if one amp goes down.

OK nice 👍. This would obviously be a mono setup right? Is it normal to run the tops mono for dj/bass music anyway? Because I'd also like to play all sorts of music through it and it would be nice to have the option to run the tops in stereo. How does this affect things? Thanks for reply.
It would be stereo, one amp per speaker stack that is if those amps can be set with different crossover points one each channel. Amps that can do that also can have an option for an internal Y to send the signal to both channels from one input.
To answer your original question just make up Y cables to split the signal to both amps.
Of course, cheers for clearing that up. But I was going to buy 1 amp to match subs power and a lower power amp to match tops. Which that method wouldn't work for right, or am I missing something? So I'd say Y cables are probably the easiest solution for me I think 👍 Thanks!
Does anyone know if this amp would run a 450w RMS 8ohm sub + 150w RMS 8ohm top off each channel with headroom? Lots of conflicting info on the net about this subject. If I could get away with the 1 amp that would be huge. I'd have to work out if the built in crossover would work for this setup also... Cheers!
No it is stereo. Stop and think about it for a second any will understand. The L and R channels are still completely separate, the power amplifiers are just doing hi and low the same way they do inside a powered speaker.... instead of L and R.

You can't run a top and sub off each channel... well you could be there is no way to limit the amount of power the top gets so they would get blown pretty easily.
With only one 2-ch amp your only option is both subs on one channel and both tops on the other, with crossovers and limiters set correctly that would be safe but stereo sound is not an option.
Two NX3000D, one for left and another for right seems to me like a much better option than a single NX6000D.
Alternatively the Quadro 500 from Thomann is a 4 channel amp with DSP that is reasonably priced and gets decent reviews.

With a 4 channel amp with integrated DSP you would get the "EQ > Crossover > Amps >" parts in a single box.
Let's just say DJ's can tend to push a system a little hard and a 450watt sub is a little light considering what is available these days.
You should put at least a basic limiter in line before the crossover or the amps if you go with amp that have internal crossovers or go with amps that have limiters that can be adjusted.
Limiting can be tricky, pushing peak limiter into hard limiting can actually raise the overall RMS power level from the reduced dynamic range.
