    • Not very powerful for the price
I've had the amp for awhile now and it's pretty disappointing for the price sucked at pushing my door speakers is currently being used as a mid/high amp for a loud speaker and 2 3.5 full ranges Pros reliable has never gone into protect mode Great for a center channel or a really inexpensive set of door speakers Cons gets really hot Low rms rating Won't get anything close to 1100 watts out of it More powerful amps in the same price bracket ... show more

    • Its a amp
Its a amp, works well. Bought to replace the 20 year old pioneer 760 that was stolen from my truck . Sounds good, well see if it lasts like the pioneer. On a side note this one costs about 1/4 of what I paid 20 years ago for the pioneer .
