So, I have a Yamaha A800 and a Behringer 2000w amp. Going to power up 4 AE IB15s. I know it's not optimal, but it's what I got. If this won't work, I might just go with 4 sealed 15s instead.

I'm assuming I just run the sub outs to the amp as normal, but how do I physically wire up the subs? What's the best configuration, and what kind of wire should I use to handle the power?

Thanks in advance.

It depends on the impedance of each driver and if they are single or dual voice coil. Generally you want a 4 ohm final load so you can run the amp bridged. 2 ohm load is too low and 8ohm won't draw the full potential of the amp.

2 ohms is not too low with a Behringer if you run it in stereo mode. I've been running 8 drivers this way for several years, and it works fine.

My IB15 drivers are 8 ohms but they can be ordered either 8 or 4 ohm. Which ones do you have? It should say on the sticker that is attached to the magnet.

You can use 14 gauge wire or thicker. Wire two of the drivers in parallel and connect to one channel of your amp. You do this by using a wire from + to + on each speaker and then a wire from + on the amp to + on one of the drivers. You can strip a section of the wire with a knife and put the wire through the binding post with the end going to + on the 2nd driver and the stripped part at + on the first driver with the beginning of the wire attached to + on the the first channel. Do the same with the - .

So do I but that is 2 ohm stereo. 2 ohm bridged mono is actually 1 ohm internally.
