[Shotimes] (OT) audio advice, please: adding a sub to 94 CV

[Paul Nimz]

If you go to Crutchfield they have a very good description and explanation
of things.  Ported is for tuning to a specific frequency and is a bit more
efficient as far as loudness per watt.

I was very disappointed with my Bazooka Bass tubes.  Could not get them to
sound good no matter what I tried.  I now have a mono amp 400w and a 1 cu ft
seal box with a 12" and it suits my needs.

Make sure your power wiring is at least 4 ga coming directly off the battery
and you won't need any caps.  Use 4 ga for the ground too.  Don't need that
fancy "oxygen free" wire unless you are an absolute perfectionist.
