PPI had some good amps in the day but that one...idk about. Have to agree with Shredder2 on that one. Max on that is 2500watts @ 1 ohm with a burp of possible 5,000.
Yeah ever since PPI got sold their amps went to sh*t. Most of their amps don't even make what they advertised since then, some don't come close. PPI used to be a top tier amp, not anymore. Glad mine was before they got sold and actually makes what they advertised for it.
Also..with regarding the sub Skar here...You will see quite a few say Skarbage, never used them myself but have seen enough pictures over the years of damage products coming from factory.
Idk about their amps though as they seem to be the same boards as Sundowns, Cresendos and a couple others but might be wrong. Just going off what I have seen on Willistons youtube.
