10-inch-diameter speakers

[Ben Bradley]

The key question is whether a car speaker should be installed pointing
to the rear for better thrust and improved fuel economy or pointing
upwards for more traction.

See http://www.tinaja.com/glib/marcia.pdf for a detailed analysis.

To do this you need a speaker with full response down to DC. This
is the only model I've seen that has this feature:

It might start sounding funny if the output transistors start
overheating.

You mean when the sound stops ?

I would get some of those Spinal Tap model 11-inch speakers.

Obviously rated for 11 on the volume knob.

Yes, can't go far wrong there if the room is rated to take it.

Including something I didn't notice earlier: "TOTAL IMPEDANCE: MORE
THAN 4 OHMS".

Besides the obvious, what does this mean? What are the hazards of
putting in Exactly 4 ohms?

Too low of an impedance should pop the speaker fuses - that's what they are
there for, to protect the amplifier's output stages.

What fuses ?
