ohms

can anyone explain to me about ohms? do your subs and your amp need to be the same ohms? thanks

What do you want to know about ohms? Your amp and speakers dont have to be at the same ohms but to get better power out of them its better to run the speakers at a low ohm and make sure your amp can handle a load that small. If you have a amp that goes down to 1ohm stable and wire 2dvc up parrelle and run the speaker at 1 ohm you will smoke the amp. hoped that helped a little bit. Any more questions just e-mail me [email protected]

actually you won't smoke the amp, if it is 1 ohm stable and you run 2 dvc's in parallel which equals 1 ohm, the amp can handle it. You just want to make sure that the amp can handle the impedence of however you wire your speakers. A lower ohm load is also easier on your electrical system of your car. I was running to audiobahns in 8 ohm because i only had 1 speaker terminal when i was building the box. I think i went through 4 alts in 6 months. Finally got another speaker terminal cup in the box, rewired the subs for 4 ohms and everything is otay now.

smaller or lower ohms actually equal greater load on your amp. If you put to low an ohm load on the amp, the protection circuits will usually kick in before the amp blows

the reason i was wonderong is because my amp stopped working and i don't know why. i have 2 kicker comp vr subs and i have a sony xplod 1000 watt amp. i had the subs wired parallel i think and then i started blowing fuses on the amp and then it just stopped working. if you have any ideas of what it might be i would really appriciate it. thanks

sounds like a blown transistor to me. Heat is electronics worst enemy, if it was blowing fuses it was over heating for what ever reason. After so many over heats the transistors are normally the first things to go.

are those replacable?

check your warranty for a list or service centers, transistors are replacable and most times less exspensive than a new amp

i need you to explain this to me. Why do people keep saying that running lower ohms makes the amp run more efficient, and that's why you're able to get more power out of them? I know that going below the load that an amp can handle will clip the signal and destroy the speakers and is overloading the amp, but honestly, lowering my load from 8 ohms to 4 ohms did wonders for my electrical system and I stopped frying alts, or maybe it was all just a fluke.

an 8 ohm speaker operated at 4 ohms will increase volume, less resistance produces more thurst if you will , so actually it is lessening the load on the amp but increasing the work on the speaker, hence you would blow the speaker before you blow the amp

sony amps will fry easy, it happens many times, they are really pieces of shit, 2 dvc speakers wired in pareelell WTF are you talking about? coils on subs can come in .5 .7 1 1.5 2 3 4 5 6 and 8 , single voice coil, dual voice coil and for the crazy guys(likemyself) QUAD voice coils,
2 dual 4 ohm speakes wired all in parelell will yield a 1 ohm result but wire in series then parelell will yield a 4 ohm load, hey hit me up on aim at hammerdgolfer if you have soem questions, when wires dont get wired right, a whole system can be uselss

I will try .......

first some electronics equations
Volts = Current (amps) X Resistance (ohms) ....... (ohms law)
Power (watts) = Volts X Amps ... when you substitute amps X resistance for volts (ohms law) you get Power = volts^2 x resistance
For some numbers:
100 watts = 10A^2 X 1 ohm
100 watts = 7A^2 X 2 ohms
100 watts = 5A^2 X 4 ohms
so you can see that a 1 ohm load draws twice the current as a 4 ohm load. In case you are curious, the (excess) current flow is what causes the excess heat. Efficiency is how much of the power the amp draws from the battery that is being converted to audio power. Efficiency IS higher as the amp is played harder, so I suppose loading it down will make it more efficient. Lowering your speaker load from 8 ohms to 4 ohms should have increased the load on your electrical system (all other things being equal). Clipping, in and of itself, does not fry speakers - power does. When you clip a signal, you cut it's top off - but the amp stays in the max power mode for extended periods. It increases the area under the curve for power and just simply overworks a speaker until it fails.

thanks, that helps my understanding, still got loads to learn i guess
