your doing a good job of making everyone not want to help you at all. people on the forum kid around and if you cant take it then stop posting. your just making it worse by arguing with everyone. if you've been into car audio for 20 years how do you have no idea that under powering a sub is perfectly fine? Asking if it was ok to underpower the sub wasn't the question douchebag!! Way to twist my words around. Some subs don't come alive until a certain power point and that is what I wanted to know. I have heard decent things about the Fi Q and was wondering what the deal was with them. To tell you the truth, I heard their customer service is horrible, and now to see their forum members are a bunch of class d rocking douchebags....I think I will go with the incriminator audio Flatlynes. I have heard none of Fi subs can even compare and the price difference is minimal. Buddy please stop displaying your emotions on the screen, this is not a PMS Forum for monthly feminine poblems. wow..kids these days.
