Just wanted to give Hawg Wired a shout out for great service. I had an audio problem I thought was the amp which is well out of warranty. I sent in the amp and cross overs to be checked out. They tested and found the amp to be fine and also replaced the crossovers free of charge. I felt this to be above and beyond their obligation. Very friendly people, even offered me a cell phone number in case I had any questions over the weekend.This will definitely be my first choice for any audio purchases I have in the future. It turns out the problem is in the stock HK head unit so it looks like I will be sending it to Iron Cross pretty soon.
