it is with great sadness that i am trading my x5 hopefully to get another! anyway, i have the pioneer sub, alpine amp and enclosure for sale. its built to the specs in essams threads and is awesome. if you search this thread you can see the pics i posted. I will take $300 for the whole deal shipped to US or maybe Canada. please email me if interested. [email protected]. please dont send a pm as i dont check this often.
