Hi all. I'm on a tight budget and looking for a cheap, simple solution
to add some bass to go with the factory speakers in my regular-cab,
full-size Dodge Ram. I'm not wanting tons of bass, but just enough to
add some punch to the kick drum and beef up the bottom end a little
for a good, solid mix. I'm usually listening to metal, classic rock,
electronic/dance, and rap on occasion. I crank it up some now and
then, but I don't ever get it REALLY loud.

I'm not concerned about being able to upgrade later, and, again, I
have to keep the cost down, so I was thinking of going with a powered
sub tube. I'm guessing that going with a passive sub and an external
amp requires other components, cables, etc. and a significant jump in
price even if I don't go all out for the best equipment. Is that
correct? Also, while surfing the net, I came across 3-way mid-range
speakers that cover highs, mids, and lows, with a frequency response
of 30Hz - 30kHz. Since their range goes down to 30Hz, would they
eliminate the need for a subwoofer? Would these be used as a pair and
replace the factory mid-range speakers?

Any help, advice or thoughts on what route I should go will be greatly
appreciated!
