your radio output will be 50watts per channel, your speakers can handle UP TO 600watts so your speakers and stereo will get along famously.

[QUOTE 3999222, member: 9609"]I thought that would be the case, but was not sure the broken speaker is rated at 80w

Also Impedance 4ohm or 8 ohm, what is all that about[/QUOTE]

An amp driving into the higher impedance will sound louder flat out.

Or put another way, the 4 ohm speaker will need more grunt from the amp to produce a listenable volume.

Shouldn't matter in your auto application, provided all the speakers are the same impedance.

It can be relevant in a hi-fi set up where a 4 ohm speaker can produce a richer sound.

But it does need a chunky amp to drive it, so most hi-fi speakers are 8 ohm.

two different things here. A less efficient speaker will need a more chunky amp to get the same volume. A 4 ohm may be more or less efficient than an 8 ohm speaker so may be louder or quieter for a given amp. A given amp might or might not be happy driving a 4ohm speaker

My current (no pun intended) house speakers are 4 ohm and are much louder for no1 on the dial of my amp than the 8 ohm pair I had before. I don't know for certain if the amp is pushing out more power into the reduced load for a given setting (probably) but again i still recon they are a good bit more.efficient. Not because they ar 4 ohm but just because they are more efficient in turning electricity into sound

As you say, there is quite a bit going on electrically in an amp/speaker set-up.

Generally, a 4 ohm speaker will take more driving than an 8 ohm one to get the same volume you feel in your ears.

But the design of the speaker in other respects comes into it.

[raleighnut]

For a guide to volume of a speaker you need to look at it's db rating which is normally referenced to 1 watt at 1 metre look for a figure between 96db(very loud) and 80db(not so loud)
As for power it depends if the amp is rated at PMPO (the maximum it can possibly put out) or RMS which is also quoted up to a certain level of distortion (generally 1% between a certain frequency range)

I must admit, that although I'm quite comfortable with Ohms, volts, power etc and even the difference between resistance and impedance, I'm still unclear on what my amp is really doing in real life. Certainly my 4ohm monster kefs are a lot louder for a given amp setting, but less sure if the amp's pushing out double the power for a given setting. It's a meaty enough amp but I only run it on "1" on the dial, so possibly a titchy amp would have been fine - or maybe there's (a lot) more to it.

Appologies to the OP - this is no help at all I know

Gearbox bearing is on the way out on my van too @User9609 ..new big amp and 1000w speakers will be cheaper fix

Just been and had the bearing checked..the new wheel bearing is a duff one..Relieved to say the least..
