Newbie Ice - How To?

Sorry I has selected the wrong group!

This may be of interest to you :-)

"Dongo!" mumbled:

You need a car radio group...go look for one.

I like women to have a fat arse, too. Can't stand spindly women that make you think of LS Lowry.

NEVER EVER WIRE SPEAKERS IN SERIES unless you double the Ohm rating of them. This is because the amplifier is designed for a specific impedance. By connecting speakers in series you reduce the impedence. This can lead to thermal runaway within the amplifier and fry it.

For example, if the originals are 4 Ohm, connect two 8 Ohms in series instead.

Also you're getting crackling at high volume because there is an insufficient supply to the head unit/amp. You need to use decent thick cable for the +12V and earth wires.

The only way to wire speakers is one per output.

Conor Turton mumbled:

Eh?

Unless you've discovered some radically different laws of physics, you are of course *totally wrong*.

If you use the word parallel instead of series, it almost makes sense.

That would give 16 Ohms. See comment above.

One cause, but not the most common one, which is saturation either of the amp or the speakers.

erm

Conor

You're taking drugs aren't you? if not you should....

Speakers in series INCREASE impedance (R1+R2+R3 etc), speakers in PARALLEL reduce impedance (1/(1/r1 + 1/r2 + 1/r3 etc)

This is pure bollocks. Wiring speakers in parallel *might* cause the amp grief, but wiring them in series reduces the current drawn from it.

But you shouldn't wire speakers in series for the best sound anyway.

Speakers work the opposite of resistors. Connecting them in parallel increases the IMPEDANCE, connecting them in series halves it.

Sorry one and all..you're right. Goddamned wedding has fried my brain.

Oh you get better and better. Keep it up.

Think 'someone' issued a cancel on Connor's post, as it hasn't appeared on my server. ;-)

Conor Turton mumbled:

They're not true inductors, you know. They're not capacitors, either...unless you happen to have a set of those nice Quad Electrostatics.

Trust me on this...I used to install thousands of them for Rediffusion.

I did after I realised I was perpetuating my lunacy.

Conor Turton mumbled:

I did a spot of lunacy today...replaced the wrong wheel bearing. Honest, it sounded like it was the nearside...and when you turned towards it to lift the weight off it the sound went away...and when you steered away from it to throw more weight onto it...it got louder.

Put it all back together and it's just as bad. Took off the other hub...and yup...it even feels rough.

Bugger.

On the Maestro? Me and my brother did exactly the same. Luckily, he had a spares car, so it was swopping the assembly rather than new bearings.
