Posted May 17, 201114 yr I'm looking at possibly running three 4 ohm subs, which would give me a 1.34 ohm load (of course, you all know this already ). How much power would I lose if using an amp that does its power at 1 ohm?
May 17, 201114 yr I'm looking at possibly running three 4 ohm subs, which would give me a 1.34 ohm load (of course, you all know this already ). How much power would I lose if using an amp that does its power at 1 ohm?Every amp is different, different efficiencies, etc.But you could guess that it would be between the 1ohm rating and 2ohm rating...Will the power decrease be audible? Probably not Don't forget that your impedance is jumping all around when playing music, so your never seeing your 1ohm power rating...
May 17, 201114 yr You would'nt tell the difference. Lol with the driver's impedence curve it will not be 1.xx ohms anyways.
May 18, 201114 yr Author The problem is that all the amps I'm finding within my budget do either too much or too little power for the subs I'm looking at using.Edit: I'm looking at Audiopipe amps. Edited May 18, 201114 yr by Dan208
May 18, 201114 yr The problem is that all the amps I'm finding within my budget do either too much or too little power for the subs I'm looking at using.Edit: I'm looking at Audiopipe amps.One word: Nonsense.You don't need any specific amount of power, aka RMS for them to get loud. If you have less, no big deal. If you have more, great, it might be louder, but it also may be a waste.And to make yourself feel better, you can always get an amp that makes too much power and gain down...
May 18, 201114 yr Author what subs are you talking about? Dayton Classic.And to make yourself feel better, you can always get an amp that makes too much power and gain down... I had thought about that but wasn't sure. I still don't know quite a whole lot about what I'm doing and don't want to fry a bunch of equipment trying to learn.
May 18, 201114 yr As was said, not enough to make a difference.But if it floats your boat, you could always guesstimate it based on Ohms Law. Basically all you need to do is figure out the voltage output the amplifier of the amplifier at rated power, then figure out the power output with that voltage driving your load. An example; amplifier rated 1000w @ 1ohm. First we find the voltage with the formula sqrt(Power * Resistance), so sqrt(1000*1) = 31.62V. Now we just calculate power into the 1.34ohm load with the formula Voltage^2/Resistance, so 31.62^2/1.34 = 746w. So ideally that 1000w @ 1ohm amplifier would output 746w @ 1.34ohm.
