Doesn't quite make sense though. "Home" drivers tend to be cheaper. And
IMO better looking.

im guessing this is why.

That is pretty much what I have suspected for some time. Car speakers not
only look nice but they are reasonably cheap.

Why do you want to use car speakers anyway? I'm not really grasping
your
situation.

I
thought he could make my the box.

It might actually work!

The 4 ohm thing may still be a problem. Althought my present amp has a
switch for 4 ohm output:

I have never seen another hi-fi amp which will do it. Normal hi-fi
speakers
have 8 ohm impedance and amps will tolerate 4-12 or 16 but i think
starting
with 4 would be pushing it. The amp may heat up etc.

What do you mean when you say 'a sub with two 4-ohm voice coils can be
wired
to present a 2-ohm or 8-ohm load' and how would such a wiring system
work?

I was planning either to buy:

1) 3 or 4 pairs of fairly cheap speakers and parallel wire them all
the
same
2) 2 pairs, one mid/sub and one tweeter and use a cross over to make
them
more like convential hi-fi equipment.

I really like the look of:

but they are a bit pricey.

Where do people from the UK buy their car speakers?

Thanks for the help folks

Whoever told you that it won't work is wrong...

The 12v that powers the radio/amplifier/etc in a car has nothing to
do
with
the speaker impedence...

You can certainly use 'car' speakers with a hifi system, if the
terminal
impedence is acceptable for the hifi amplifier.

Most aftermarket speakers are 4-ohm, except some subs that are 6-ohm
or
dual
voice coil. A sub with two 4-ohm voice coils can be wired to present
a
2-ohm
or 8-ohm load.

I had this idea for a summer project to keep me entertained:

I have been reading about making home stereo speakers.

I want to do this using car speakers, not traditionally hi-fi
speakers,
anyone tried it?

I like the look of Kenwood and Sony models, and I have my eye on
the
KFC-1758S and XS-V1633.

It's just an idea for a project for the summer. I have a stereo
amp
which
will switch between 4 (cars) and 8 (Hi-Fi) ohms. I want to use
this
to
drive
car speakers but
someone has told me that it won't work as cars fun on 12 volts
(which
I
knew). But thinking
about it and applying Ohms law (V = I x r) I don't see why the 12
volts
supplied by the battery
matters.

I am aware of the 4 ohm (car) and 8 ohm (hi-fi) difference. Any
other
problems? Anyone have any experience?

Also, are all car speakers 4 ohms out of interest?

Thanks
