They say 1 ohm. NOT STABLE, idiots. I really don't know how can you manage burning amps. I think you are a bit parallel with car audio technique. Don't over range the gain (it isn't a VOLUME, it's a compensator). Bass boost is in about an 18dB range. Again, for compensation. In case you need to keep bass much lower in your head unit without HPF, so long and so forth. If you want 1 ohm (stupidity) buy competition amps. At 1 ohm, you may consider your final amplifier module short-circuited, but it still has to work a bit harder even for BRANDS (eg kicker, cerwin-vega, GZ, etc.).

This is the best mono amp in the market! The RMS level almost identical to Hifonics Brutus BRZ2100.1D. In fact, BOSS NXD5500 is even more powerful.

I have done a TON of research and this amp IS 1 ohm stable but only if you can give it the power it needs. You can't run this amp without a "big 3" upgrade in your car or it will burn itself out when your stock wiring can't supply the needed power. It is good to run 1/0 gauge wire all the way back to the amp too(a 20 foot spool costs $80-100 because it's that important). Also, you will almost cartainly need a high output alternator and a deep cycle battery. I plan on buying this after I do my big 3 upgrade later this month. I will be pairing it up to 2 Boss AR12D subs. 2400W RMS total 4800W Peak will be my system.
