I did see some BNEW wrapped wrenches man.. LOL. Ive been around car audio since late 80s.. Before amps hit the market in my area, and more than 60 miles to the nearest Audio shops. I learned on my own for a very long time and ended up working in Audio Shops installing after working 30-50 hrs in hard construction,. I also learned along the way.. I have had so many audio systems myself, and I still like my audio. Im still learning even today.The internet is a vast of information and also learning from others as well from theyre great experiences as well as failures.Ive had plenty of failures in my time. If I can share my experiences with others to help as well as save some money..(as this can be an expensive hobby) its worth my time.
