[QUOTE="Puff the dragon, post: 5383, member: 540750"] My volt meter isn't really going any were. It is staying at 14.4 volts. So I know that isn't the problem. I talked to a guy today that said the subs may be bottoming out because of the box being the wrong size. They might not have enough space at the low notes. Is this possible?

Good luck, Todd Huffman I guess I'll try that before I go ripping apart a $1500 box! thanks every one. help is still welcome :-) [/QUOTE]
