View Full Version : Does Size Really Matter?

No, not "that" size. Now get your minds out of the gutter. What I'm
talking about is the size of the vehicle

You see, my last car was a '92 Nissan Stanza and I had two JL 12W3's in the
trunk driven by a Rockford Punch 225.2 (112.5 watts x 2, 450 watts x 1), an
older Rockford amp, made before they got crappy ;). The bass really
cranked, I hit 142 dB at a local dB drag. I know this isn't much compared
to some of the monster's you guys have, but I didn't really design it to be
a bass machine (and my amp isn't that big) so it seemed a lot to me.

Anyway, about a year ago I traded my Stanza in on a '99 Subaru Forester. I
thought the bass would be MORE because the sub box sits in the back and is
not separated from the cab as it was in the trunk of my Stanza. WRONG. The
bass seems to be less, in fact, quite a bit less. I have tried aiming the
subs towards the front as well as the rear, but this has little effect. I
notice that when I open my front windows, the bass increases, this never
happened in my Stanza (so clearly there is some cancellation going on here).

Is this because the interior of the Subaru is so much bigger? Would this
make that much of a difference? Anybody have any thoughts on this or
similar experiences? Any tips so that I might increase the bass? I have
tried Dynamatting the rear hatch (actually, I didn't use Dynamat but a
similar petroleum based product). I am considering buying another 12W3 (or
two) and building a new box (I have an amp, a Soundstream Ref. 700 that I
will use as a sub amp, it can handle low impedences).

Thanks,

MOSFET

I don't know much about subs or the way soundwaves work but I think it has
less to do with vehicle size and more to do with the fact that you now have
a hatchback instead of a sedan/coupe.
