I bought this thing like, a year ago and finally got enough funds to add an amp. Well... I get everything torn apart and it's not even close. My plugs are smaller and more compact. I have a 2008 Mazdaspeed 3 with the Bose... said it'd work with the Bose. Well, it will not. Suggestions? Someone has already been in there and there's 4 leads off 4 wires going into the amp. I'd prefer not going that route. I wanted to use the OEM amp interface. Please help? (gah)
