i have an 8 gig ipod touch for trade i am looking for a subwoofer amp that does minimum 300w x2 the ipod works perfect except sometimes the external speaker doesnt turn on. You have to put in the headphone jack and pull it out and it works fine. Other than that the wi fi and touch screen work like new. Minor wear and tear on the bck metal does not affect performance. Thanks for looking its an amazing little gadget!
