This will be a very novice question. I am thinking about doing a DIY sub and began to look at Amps. Just as an example the Behringer iNUKE NU1000 has 1/4" and XLR connections. What do you use to connect the RCA signal from your reciever In to the amp and what do you use to get the signal out to the sub?


Sorry again for the question, I have been in bands for years and never thought to use one of my friends Bass "heads" to power a home subwoofer.

You'll need to get an RCA to XLR or RCA to 1/4" stereo plug to connect the amp to your receiver. Then you'll need some simple speaker wire to go from your amp to your sub. Wire gauge will depend on the length and impedance of the sub driver. 12AWG copper should be safe for most, but 10AWG would be better.

RCA to TRS is what it's called.


I use 35ft runs of 12AWG which allows my LMS-18's to reach full excursion with 8kW iTech and clone amps, I'm sure it will be more-than-overkill for a nu-1kW.

Purchasing the correct wire or cable is not easy. Getting the correct connectors and length you need can take a lot of time and money. Making your own cables could be a great alternative. If you need rca cable that is 8 feet long? Get the 12 gauge wire and cut it to length then put some of you favorite color of flexible sleeving on. Use heat shrink, also available in your favorite color, to connect the sleeving to the connector. You will be dang proud of those cables when you are finished! I intentionally left out some steps and procedures to make my point that "You can make your own cables!"

I also have a clarification question on this..I have heard the fans are loud on these amps...would replacing the 80mm fan with a lower rpm fan be ideal for a home setup?


Also, on the outbound connections on the iNuke 1000 there are no speaker wire outs so would you modify a cable or what would be done there to change it back to bare wire for wiring up the woofers?

mrbrace, you'll need speakon NL2FC connectors for the amplifier output and 12/2 speaker cable. If you're using binding posts on the sub/s terminate the wire with banana plugs or you can use the chassis mount female speakon connector.

Ya I saw the speakon to 1/4" connector and then was going to use a phono 1/4" from that and split off into the 12/2 wire cable but on the inuke there is not binding or banana plug option according to the screenshots...not that it matters.


I was thinking of going to epq route anyway that has terminals i can connect the speaker wire directly to...


If that all makes sense lol

On the sub, not the amp. Receiver output rca>trs to inuke input. inuke output NL2FC>bananna or NL2FC depending on what input your subwoofer has.

I saw a pair of speakon to bananas speaker cables on either Zzounds or Sweetwater, heavy guage and low cost. Pro guys care more about functionality than the high end speaker wire companies. I side with the pro guys, so did Mr Dunlavey (a deceased high end speaker manufacturer who used normal wire at trade shows until he discovered it was hurting sales because many audiophile hear with their eyes.

I had another question on the behringer power amps.


They are showing that only one channel can run a woofer or basically use the crossover. Would this matter since its controlled by my receiver anyway so I could use both outputs?

For the inuke1000, ya, probably only one sub per channel. It's rated for ~300w x2 into 4ohms. I'm running dual Emminence mfw-15 drivers and their power handling is only about 250w.


Depends on the sub you' reusing, really. It doesn't matter to the inuke, your receiver's crossover will only allow frquencies below that setting to go to your amp and sub, if it's 80hz, then everything below that. Is that what you meant?

You can also run one sub off the inuke in Bridged mono at ~1000w into 4ohms...or if you had two dual voice coil subs you could wire series/parallel for 4ohm. etc, etc.

With Behringer, like most brands, be sure to download the manual and carefully review the specs. Behringer provides RMS numbers, which are significantly lower than the numbers posted on websites. However, all brands do this to some degree. For many you want to look at distortion numbers from 20 Hz to 20 kHz, which again will be lower than the touted power specs.
