I have had this amp for just under a year , i am pushing a 1200 rms sub @ 4ohms, recently reconfigured to 2ohms , it played for about a month the suddenly one morning no sound from the sub . The power light was on , protect light off , but no sound. Thank god for sonicelectronic great customer service , they had a rma ready for me by the next day .

Overall the amp is great, it sounds good, i pushed it alot @4ohms, but i think the combination of the 100deg+ summer heat and the extra load @2ohms broke it.

I have had nothing but good to say about boss i have had it now for 1year and it runs with 2-2000watt 12,kenwoods premeirs i just added 2 more boss amps a ph4.600 4 channel and a ph2.1300 and for the money it rocks,i noticed a couple reviews and they said they were disappointed,suggestion adjust your amp or amps if you dont you wont get the sound you are looking for,i think my system for the money now 4,12z 2,6by9z,2 6z and2 6by4z it is sweet and i found the sound that i was looking for!

If you keep it on 2 ohms it bangs, but wired down to 4 it's very week.
