hifonics is what everyone up north uses.... the hot 97 truck has a whole hifonics system that theyve had for some time now..... and it hits as hard as it did back when i was in like 5th grade.... ive had a few pyle products myself and they were ok for the price but that was back in like jr year.... hifonics also has seniority cuz theyve been around alot longer and have made many good amps and such....
