On another note, I don't know why everyone bashes the owner, nor do I care. DIYMA is about 10,000x better than this website when it comes to information. It's a shame people want to take it down, one of a very select few sites you can get quality information.
All car audio forums have strengths and weaknesses. Most suffer from unqualified people providing bad advice and needless bantering and name calling. There are some great people on DIYMA and they can handle very advanced topics.
