Hi again, I have decided on a Soundstream amp for my Dodge 4x4 Quad cab with Infinfity Kappa 60.7 CS 2 way component speakers. I am looking for quality sound. I may or may not add a sub. My question is would it be worthwhile to pay a little extra for a better THD and Signal to Noise rating or will it not be noticeable in my truck? The two choices with similar power are below; http://cgi.ebay.com/SOUNDSTREAM-TRA...oryZ4950QQssPageNameZWDVWQQrdZ1QQcmdZViewItem OR http://cgi.ebay.com/SOUNDSTREAM-XTA...ihZ007QQcategoryZ4950QQtcZphotoQQcmdZViewItem I can get the latter for $152 so the actual difference is about $27. OJ:huh:
