power into ohms?

allright so what does it mean when the amp specs say "Brigded into 2 ohms : 700W x 1 " or "Per channel into 2 ohms : 350W x 1 (0.3%) / "Per channel into 4 ohms : 200W x 1 (0.08%)" what does this mean? how can i tell how mine system is setup in ohms? or whatever the f**k, im obviously confused :errr: what im trying to get at is how do i measure or find out how many ohms im running at

your subs or speakers or w/e you call what you are running off of the amp come in impedences. running 1 speaker to a channel will give you that impedence (measured in ohms) at that channel when you run two speakers or two voice coils in series or parallel is when you being to change the load the amp "sees." if you run two voice coils in series you effectively add the impedences of the two voice coils together and this gives you what the amp will "see." when you run two voice coils in parallel with the same impedence then you effectively half the impedences the amp "sees." refer to https://www.the12volt.com/caraudio/boxcalcs.asp for help with this...

if you name the make and model numbers of all of the equiptment in question this forum will be able to help you much more.

Your subs will probobly list their impedance in the owners manual or on the back of the magnet on the subs. For instance if you are running two single voice coil subs that are 4 ohms each and you connect them to the bridged output on your amp your amp will see a 2 ohm load. Post the modle of your amp and subs and we can help you better.

i have an alpine MRP-M350 and 2 jl 10w0 which are 4 ohm single voice coil. so im seeing a 2 ohm load then? since my amp is a single channel and i have both positive and negative for the subs running from that channel means its bridged right? sorry im a little slow on the technical terms of all this

yes that is correct. each sub should be getting about 350wrms

is it bad that my subs say 125 watt power handling? i asked this on here before and they said it should be cool but now im not so sure, the subs dont sound as good as they used to im wondering if im melting the voicecoils.

The RMS power of that Alpine mono amp is 350 watts into a 2-ohm load.  Your speakers will split that power, so each is actually receiving about 175 watts.  Your 10W0's are rated for 125 watts RMS, so you are overpowering them.  If they are in a small sealed enclosure they should be able to handle this, although if the system is running near it's max too often they will eventually fail.  If they are in a ported or bandpass enclosure, or a large sealed enclosure, you will fry the voice coils much sooner.  If the amplifier is clipping (gain set too high) then all bets are off and your speakers are almost certainly being fried.

cool they are in a small sealed enclosure so i guess theyre ok for now, i think the gain might be set to high, anyway thanks ima go mess with them :)

Make sure that you get that gain turned down. To expand on what Dyohn stated earlier about the overpowering becasue most people overlook this fact. If you overpower a sub and play your subs at a consistent volume level (I know you will be) your subs will be prone to failure, this is because the power sent into your subs is also transformed into heat when power is applied. This heat when played at sustained volume levels will melt the voice coils or former if the subs are not allowed to cool. Play it safe for 3 reasons, don't annoy the neighbourhood, allow the subs to cool and most important, you will never get damaged hearing back.
