Did you by chance explore White Noise Noise canceling machines. There are mechanical devices that create a sound like wind blowing. Because they are mechanical, they break up airwaves and diffuse them.
Also, rather than pure continuous White Noise you might try audio tracks like Rain or Ocean or similar. These are relatively easy to find.
As to wiring speakers, there are certain combinations what work best. First can we assume the PYLE speakers you bought are 8 ohms. The impedance matters.
The best combinations are FOUR 8 ohms or NINE 8 ohm per channel. THREE speakers on each channel, for a total of SIX is an odd combination that doesn't fit well together.
In a sense, the goal is to come up with a combination of speakers, that fall in the range of 4 ohms to 16 ohms per amp channel.
Here is one example of 4 speakers wired in a way that the total is the same as a single speaker -
Speakers in Parallel Divide, so Rt = O/n = Impedance in Ohms of one speaker / number of speakers = 8/2 = 4 ohms
Speaker in Series Add, so Rt = R1 + R2 + R3 + ... = 8 + 8 = 16 ohms.
In the Diagram we have we have two banks of two in parallel, then those to banks connected in series.
Two 8 ohms speakers in Parallel is 4 ohms (Rt = 8.2 = 4). To 4 ohms banks in Series is 8 ohms, assuming you are using 8 ohm speakers (Rt = 4 + 4 = 8).
In the second example, you have two banks of two series speakers. Then those two banks are wired in parallel. So, two 8 ohm speakers in Series is 16 ohms (Rt = 8 + 8 = 16). Two 16 ohm banks in parallel is 8 ohms, exactly the impedance of a single speaker (Rt = 16/2 = 8)
This can also be done with 9 speakers. THREE 8 ohms speakers in parallel is (8/3) is 2.66667 ohms. Take THREE Banks of THREE and wire in series and you have 2.66667 + 2.66667 + 2.6667 = 8 ohms. That is more speakers than you need, but it is a further illustration of the point.
So, if all the speakers are the same, in Parallel -
Rt = O/n = 1 speaker in Ohms / number of speakers
In Series, any speaker of any size simply added -
Rt = R1 + R2 + R3 + ....
If the speaker are unequal and in series, each gets a signal in proportion to its individual impedance. This is not something you will have to worry about, but it is there for reference.
Now the actual wiring is not as complex are you might think. Wires can be run from each speaker back to the amp, and the Series/Parallel can be worked out at the amp. Here is an illustration of two speakers in series, wired together back near the amp -
Depending on where the speakers are, the can be wired in the wall as well. Here is an example of that -
For four speakers you simply double up on this configuration. The speaker are wired in Series, and each represents a gang. Then just wire the Gangs as you would a single speaker back at the amp. When the second Gang is wire to the amp, that is in parallel, and you have the
Series/Parallel configuration as seen in on the Right side of the first diagram above.
I don't have a diagram for it, but a
Parallel/Series set up can be wired with equal ease.
Please note, I am only showing and discussing ONE Amp Channel. The same configuration would be mirrored on the other Amp Channel.
One assume since you have a Stereo amp, you will somehow have to have Stereo Sound, so two speakers in each location, one for the left channel and one for the right channel. This will especially work best if you can find some of the Environmental CD's (rain, wind, ocean, etc...) and Rip them to your iPod.
Here is a link to one of my old posts that explains how various impedance can be combined in various ways. It is a bit
mathy but not beyond comprehension.

That should get you started.
