Did not mean to offend you sir, not at all, or provide unuseful information. If you notice what I posted, ALL are fundamentals in regards to car audio that ANY car enthusiasts should know the basics to. Especially for one who has 20+ years of experience and one that has been previously sponsered by two major companies. The questions you asked are by no means "stupid questions", or ones that concerns ANY products. Again, it is the basics of understandings that I question someone of your caliber should have an understanding of. Looking back at previous threads you have created, they ALL are very "newbie" questions for the lack of better terms. Besides that, yes, follow suggestions previously advised.
