Well I called around today, and the cheapest yellow top I could find was 170. But couldn't find what size fits the crossfire. I'm probably going to go back to the place that installed my system, hopefully, they will give me a deal, since it has only been one week, and they were the cheapest. Does anybody know what size yellow top I need? I don't want to destroy something, so for now the amp is down super low. Thanks, chris
