Watts rating on speakers?

DB lacks the awesome.

I find it fucking disgusting, and moderators' selective use of the infraction system based on social standing is even more fucking disgusting.

Whereas the use of swear words is perfectly acceptable when discussing speakers.


Anyway, back to the subject of speakers (that was what we were talking about, wasn't it?).

Wiring speakers in parallel is usually bad, as it reduces the impedance and allows the amplifier to supply excessive current and fry itself.
The only power rating that is of interest is the RMS power rating, which is how much real power you can put into them before they blow up, so obviously should be higher than the amplifier power rating.
As has been stated, sensitivity is also a relevant factor, 60W 91dB/W speakers at 50W will make roughly as much noise as 100W 88dB/W speakers at 100W

Alright, maths aside, the question was asked is it a good idea, and will it work. Yes, it will work, yes it will operate at a lower power in series, no its probably not smart wired in parallel if you are going to punish it - simple.

The question was asked about phasing - yes if you hook them up backwards you will lose 3/4 of your bass. It will be easy to just check the wiring polarity is correct, but it will be difficult and time-consuming to do a proper phase check (never rely on the +- markings for proper polarity.

Stop being a cunt cowshit.

Wheres my apologie for being correct...and for you abusing me for being wrong?

thanks for all the advice, alot has gone above my head. am i able to use a multi meter to find out which wires are the positive? i have found if i use the ohm setting and connect the positive and the negative to the speaker wires i get a negative reading and if i swao them around i get a positive reading so is this telling me which is which? it is a pain in the arse to take the dash back off to have a look.

Stick multi meter on dc 20v....turn the stereo on...ground negetive cord of the multi meter on the van [a clean metal earth that touches chasiss or metal directly...very very essential]...touch both the headunit source wires with positive lead of the multi meter....only the positive should show a result [doesn't matter what the reading is...just aslong as there is one]

modern head units utilize inverted outputs I believe, so in such a case one wire would show positive result and the other negative when using the volt meter, and don't ever ground the -ve speaker (or +ve for that matter) wire you may fuck the head unit!
