Re: 2002 Explorer
I have found that mass loading only goes so far. I am planning to use aluminum stock to brace the inside door skin, as it flexes just under the door handle....a lot! It doesn't make any noise, but you can feel it vibrate with heavy midbass. Despite what some might think, that should not happen in a good stereo system. No fault of the Damplifier Pro. There just needs to be more metal to stiffen up the door. The deader, the better.
The Top 50% of income earners pay 96.54% of All Income Taxes. The Top 1% Pay More Than a Third:34.27%...so, the next time you hear about "tax cuts for the rich", remember...those are practically the only people paying taxes.
