At the beginning of the thread the specs read 2250w @ 1 ohm. If you know squat about the Alpine Type X you would know that it only comes in 4 ohm dual voice coil, meaning I would most likely be running them at 1 ohm. So if I am running 2250 watts ( which that amp will do ) to them 2 subs how the he11 did I under power them? Please explain. To make them X's start to sound good you have to atleast give them a 1000w a peice, in my opinion and experience. I don't comment too much on here because most of these young guys know their shit on here and I listen and learn. So for me to actually get on here and make a suggestion or a comment to someone it's only because I have owned that product or I am very familiar with it. So I guess what I'm trying to say is it kinda pizzed me off you want to raise your post count up on a stupid un-educated comment to me, I'm done. Peace out.
