Money isn't necessarily an issue, if someone can explain why those amps are worth $150 more? Is it build quality...sound quality...overall brand reputation? I just want to make sure there is an actual noticeable difference. I have been a brand ***** in the past (JL, Rockford, MTX, ect...), and have heard systems that cost half the price of mine sound twice as good/loud. I don't want to fall into that trap again. I am just getting back into the world of car audio after about a 10 year lay off, so I am having to do my homework again. From what I can tell so far, the prices seem a lot more reasonable these days, but there are a lot of new brands that I have little to no experience with. I am old enough to remember the "$1 per watt" days of high end amps. Glad to see that is not the case anymore //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
