New amp for my DIY subs. My current crown wasn't a fan of being used with one channel at 2 ohm and another at 4 ohm. So now the XLS1500 will be an 300 wpc 8 ohm amp and this one will be 300 wpc 4ohm.
Doesn't sound like a lot, but 4 of these infinity 12" drivers in each corner works quite well.
Some day they'll be upgraded to 18", but that's a bit down the road.
