    Rated 5 out of 5 by from ive had mine for almost 4yrs i got this amp almost 4yrs ago and didnt have a case for it until a few months ago. it has been through MANY MANY of parties and ruff transporting situations. i even for a while had a small flat screen tv sitting on top of it... (i wouldnt do that if i were you. it did bow the top down and mest up one of the cooling fans. but after 4yrs of hard abuse one of the channels every once in awhile cuts out... im thinking of buying another for just incase and keep the new one in a case i figure it will last many many more years. i have also powered 8 total speakers at one time with just this one amp. 2 - 15 DJ-Tech professional PA speakers sx-15max power - 500wattImpenance - 80hm (this i have no clue about)Sensitivity - 98db (again no clue)Frequency - 40-20k Hz2 - 18 JBL subwoofersJRX 100Recommended power350 - 700watts4 ohms(i also have 2 dual 15 (total of 4-15 speakers) low\mid frequency house type speakers that i bought off a guy for $.
