DavidRam's 1st Audio Build... EVER! :)

[BradKnob]

Yea, just easy on the gain and volume.

 

[Etroze86]

Yes sir if you can some how wire 2ohms that would work as well.

 

[DavidRam]

What's the difference 2ohm vs 1ohm?

 

[BradKnob]

The higher the ohms the less the power, but the cooler and more efficient the amp will run

 

[DavidRam]

Below is a quote from SIs website:

"Does the BMmkIV need 450 watts to perform?

Absolutely not! The new BMmkIV is a very efficient subwoofer thanks in part to its XBL^2 enabled motor and it does not need every bit of its power handling limit in order to perform well. In its recommended enclosure volume of 0.5^3 sealed, the BMmkIV’s ideal power range is 200 to 350 watts.

What is the frequency response?

Typical in-car frequency response is 20 Hz to 500 Hz."


All that being said, shouldn't I run the subs at maybe 2 ohm?? Is that possible??

Here are the amps specs again:

4 ohms: 488 watts x 1 chan.
2 ohms: 872 watts x 1 chan.
1 ohms: 1385 watts x 1 chan.

Id run 2 ohm, isn't that the pic u sent a few min ago? Mine will be getting 380 watts each at 8 ohm. This is one of the subs that won't benefit from just dumping gobs of power to it.

After an hour of reading and searching for diagrams, I think this the right way.


Please correct me if I am wrong.

I am trying to run at 2 ohm.

Here is a diagram I made:

You got it right David.

I am trying to run at 2 ohm.

That's 2- 2ohm loads going to a mono amp which equates to 1ohm. Looks like your only ootions are 1 and 4 ohms





Edit: is that mono amp ur running?

Another edit: you put sk1200.4 in ur diagram. Thought u were running a 4 channel for a sec. That threw me off. 1 and 2 ohm are your options

Now I am even more confused, lol! I have the Sk1200.1D, that is the amp in the diagram. I don't know why it has two sets of connectors.

 

[BradKnob]

This is what threw me off...



The .4 after sk1200 usually indicates a 4 channel amp. U have a 1 channel. The 2 sets of terminals is just for ease of installation when running 1 or more subs. If u hook both subs into the right + and - or left + and - or mix and match, it won't make any difference. They all sum into 1 channel.


I would prob run it at 1 ohm and just leave the gains and levels in the DSP down a good bit

Sorry, that was a typo... fixed.

If wired the way the diagram is, would it not make it 2 ohm??

Honestly, I am a little nervous after how much Nick warned me about these subs, I definitely don't want to send too much power to them...

The way ur diagram goes, it would make 1 sub run at 2 ohms. With 2 subs, wired like in your diagram, it would be a 1 ohm load

DavidRam's Land of Audio Confusion. Now that's funny.

 

[DavidRam]

So there is no way to run 2 ohm unless I had a 2 channel amp?

Appropriate right?!

Yes.....




Or a third MKIV!!! [emoji15]

Sorry I didn't get the pics up yesterday but here they are.

 

[DavidRam]

Yes.....

You are sooooooooooooo killing me! Why did you have to plant that seed in my mentally unstable brain?!?!?!?

First pic is the depth without the front ring is about an 1and 3/4 of an inch
