$50 off each amp today with an additional 15% off promotion. These are excellent amps for the hobbiest or DIY -- especially for subwoofer duty. The DSP is excellent and connects to a PC using a USB interface. You can set exact wattage limits (great for tactile transducer / buttkicker use), set HPF filters (great for ported subwoofers), modify multiple parametric EQ bands, set crossovers, phase, dynamic EQ, etc. I've had the DSP 3000 for about a year now and it's a fantastic amp. This is about $50 cheaper than the normal sale price I've seen, and $100 off retail. These use a 24 volt fan and you can purchase a replacement silent fan from a site like digikey to keep the unit quieter for home theater duty.
These amps are 2 ohm stereo stable --- I ran my JTR Captivator pair (2ohm subs) of a single INuke DSP 3000 in stereo for quite a while. The very effective DSP allowed me to get my frequency response perfectly flat as you see in my avatar picture. Great price, Great product.
