Starting with 3 DC 18's, vehicle and power?

I'm curious to see this answer my self. i know that running below 1ohm puts allotof strain on your electrical. for eexample if your system requires 200amps at 1ohm running .5ohm your system can draw almost 400amps. (that's not exact just a exaggerated example) but i don't know how 3 1ohm loads Would be in comparison.

If you are producing the same total wattage then the electrical requirement from the vehicle is the same. Having one 5000w amp or five 1000w amps needs the same "electrical" from the vehicle when wired properly.

If you wire below what the amp is rated for that means it needs to draw more amps to produce more power than what it was designed for which is hard on the internal components, so if it can get the amperage from the vehicle for what you are trying to produce it makes it easier for the amp to do so. Also you here about voltage drop which is also in the equation. Some amps depending on whats inside do better than others.

did you just say .067ohm ????

Wouldn't this only hold true if the amplifiers were equally efficient?

i thought a 1000w amp at .5 would draw more power.then a 1000w Amp at 1ohm. even if the 1000w at .5 was designed to run at .5

(this is what I've heard) I'm just asking a question.

Sorry decimal in wrong place, meant 0.67 ohm with 3 subs wired together.

Yes the assumption was that . If the true output from 5000w amp at 1 ohm is 5000w and the output from the five 1000w amps at 1 ohm is 5000w then the required amperage is the same again assuming that the voltage is the same in both which may not be true with all the additional wire running 5 amps. May point is that there is not a significant difference.

Yes

that makes me happy, i heard that here. it's nice to know i can Trust what most people say here.

So what would you do. i have a brutus 2400 now. Get 2 more for about $600 to run each sub or get a stetsom 6k5es for about $1000 to run all 3. Not which one is better, but which is better for install, more subs means more wire, fusing, etc. but it will cost less.

[Aj11]

that's tough. I've always wanted one big Amp! I'll be running 2 2000w amps soon. idk id say get the big amp sell the smaller one to help pay for the gear your gonna need. just my 2cents.

[stipek]

Yeah probably keep it simple

Also may just do a collaboration and use my vehicle, split the cost, sounds like a good deal to me.

Just have to figure if 3 18's will fit walling behind c pillar without taking out the back seat. Plus gotta put the amp and batteries somewhere. Might have to do typical subs up and port back.
