That's actually a pretty good point. I initally want a single tip. I did some research though and it appears that the twin tips (esp. the one on brian's and johnny's tivos) are droney as hell, and stupidly loud lol.
The single seems to hum and scream alot more sedately.
YOU WANT LOUD?
this is LOUD so loud that it only stayed in my car for 2 months....
