Wow, this shit is crazy loud guys! My wipers just rattle in my windshield and my whole car doesnt flex as much as when i had the XXX since it doesnt go as low but it kills the XXX's output. My voltage does drop a little bit, now it drops to 12v. Im going to do the Big 3 tommorow hopefully then get me an HO alt. I threw in my bass mekanik CD after i drove around listening to rap for 45 mins, 1/4 of a tank worth mind you, and ****! I though rap played with such SQ, i dont know why ppl say the MT has bad SQ, mine is tuned to 34hz and it isnt that much off the XXX15. Well anyway, after i played some bass mekanik and rap i threw in my hz cd and played a 45hz tone and had my Hu at 15-20 and me and my friend Mikey were like, WTF PUT THAT SHIT DOWN!!! It moves crazy air man and its crazy loud! I cant wait to get metered. Ernesto u sold out today.
