3 sa15s ohm load

[FoRgIvEn 0]

can some on tell me what the ohm load will be on 3 sa15s?

ive used a couple different calculators and @2ohm they say 1.333, and @4ohm 2.7

but i was looking on youtube and some one says there getting like .67???

and what amp would you suggest the bc200 or bc3500?

thanks

If you wired them in series-parallel it would be a 1.3ohm load.

If this is for a daily driver system I would recommend sticking with the BC2000, I don't see the additional cost and electrical system requirements of the 3500 to be worth the minimal audible difference.

I agree totally, here is the wiring for 3 dual 2 ohm version.

Did I miss where you said that they are dual 2s?

[pmureika 31]

You would need dual one ohm coils to get .67.

Sorry it was @.66 here is the video that i saw it on

I thaught they came as either d2 or d4? do they come in a d1???

its not a daily driver its something i take out every now and then when its just me / and wife not enouph room for the kids

so id like to make it a project

thanks

Get D2s if your amp is 1 ohm stable.

I personally run 3 18" obsidians on strapped aq2200's around .7 each amp. I would recommend going the bc2k for now and maybe going another later. You will not be dissappointed as two bc2k's might just sound a little better than the 3500 because of the output of the ohm load you're running. Biggest different will be overall cost, but if you don't have the money now and have it later it will be worth it. I wanted to go bc5500 the entire time, but my aq2200 hold their own. I just recommend being prepared to back up that eletrical.

I havnt bought anything yet

im trying to figure what to buy

and what type of enclosure to build

ive planed on the wiring upgrade and batteries still not sure of the alt

If you're a cheap bastard like me then you probably want to think Tenney or Singer. Both of those guys are getting a pretty decent rep here lately. I haven't dealt with Singer, but I got one of the 270's he had on Christmas special for $240 right before Christmas and I am still waiting right now. I had a feeling it would be like this and he has changed the time he said he was going to ship a couple times, but I will keep asking until I get it and hopefully all will come out ok.

ive looked at singer but not the other i google it now

I talked to Mike and he's a good guy. He helped me get an alt for my trailblazer. 275a. It was awesome and was a tank! Good product and good guy.

From what streetlegal posted, here is the website he got it from. You can use it to help you with other configurations also. That way you wouldn't have to wait for others to respond and have any confusion.

thanks everyone

1 last ? wouldnt 2 bc2000d be way more than the SA's can handle

[EPerez 236]

People have put a lot more to them then that even. You jus have to know what your doing.

[FoRgIvEn 0]

yeah i know

ive seen on youtube were people are putting like 5k to 2 SAs

if 3 SA's gives me a 1.33ohm then with the box rise i should be could on the ohm load to strapped(i thank its 2ohm stable strapped?-not sure though)

[ricksi30 923]

thanks everyone

1 last ? wouldnt 2 bc2000d be way more than the SA's can handle

Yes, in my opinion that would be a waste of money. One 2k would be fine.

If you strapped the amps at 1.33 ohms then it would be .66 ohms per amp and that is unnessary to runs amps below 1 ohm for daily. You should be fine with 1 bc2k.

Yes and completely unnecessary unless you plan to compete in SPL. Put the $$ you would have spent on a 2nd BC2K towards much better uses instead.

There's no such thing as "box rise". Impedance fluctuates as a function of many things....heat, frequency, etc. Don't count on it to save you from blowing up an amplifier if you wire below the recommended nominal impedance.
