The secret to good sound is....
Let's stop buying cheap gear!
I am just kidding. I just wanted to tell a story. A while back when I was in High School there used to be 100W amplifiers made by Sanyo. This amp was like a hundred bucks but I remember it used to sound like a thousand. It was one of the first big amps I ever saw. I had one and I used to connect it to 2 12" , 4 8" and a bunch of m&m tweeters. No crossover! Just the little ones stuck to the tweeters. I took the rear sit off my GTO replaced it with the 12" vegas and I was the best show around school. People spent way more cash before they could even compare to me. Funny thing; I have no idea how I connected it all. I did use monster cable though. Now days it's just so frustrating trying to put a system together. There are so many things to think about and then sometimes you still end up with a crappie sound. Why? Is it acoustics? Is it power? Is it knowledge? or is it just plain luck?
