Bawls

What's up all, Here's my situation that's kind of annoying. Randomly as Im driving listening to my system which consists of: Head.: Pioneer 7800MP Front: CDT HD-62/DRT26s/EX-560i F.Amp: Arc Audio 2100 CXL Subw.: Ascendant Audio 10" Assassin S.Amp: US Amps XT-800.2 My highs will just cutout. However, they'll come back on if I turn the volume up. The arc 2100 was bought used from ebay, and im thinking that's my culprit. Not too sure. What do you think?

A little about myself: I'm a 23yr old welder in the Navy Seabee's. Currently deployed to Sasebo, Japan. I drive an '04 Nissan Sentra SpecV.
