I have had my Bazooka RS6A bass tube since the fall of 2000. It has
been very good to me and up until now has performed flawlessly. It is
connected to my pioneer DEH-P7200 head unit using the preamp outputs,
and monster cable RCA's. None of the connections or wires have been
changed. For the 6 months or so I have noticed I am not getting as
much bass from the tube as I used to. I have gradually been turning up
the volume on the tube itself to get the level that I am used to. Now
that the level on the tube is completely up, I am forced to raise it
on the head unit. Nowadays I have to raise that level quite a bit to
get any satisfactory low end sound. The amp is getting power and never
cuts out, like I said I just need to raise the level up to get a good
sound. However, at the rate this is going soon I won't be able to
raise the level anymore. For the first few years I would keep the
level on the base tube slightly more than a quater up; now it is
maxed. My questions a is this a common problem? Does it sound like
a problem with the woofer, the amp, the headunit? Any help would be
greatly appreciated. Thanks in advance!
