I have a bose ps3 2 1 ll but i dont have the sending unit just the sub and amp.the input wire to the sub can i get the wire diarahm so i can hook into my yamaha

SOURCE: Have one wire for audio sub out, but two input ports to amp

This one Wire should be for the +. Try connecting the + to the Head Unit and - to a Common Ground. At the Worst, You will Blow the Amp Fuse if not Correct. The Lead from the Head Unit is Only an Off and On from the Ignition. Please Rate My Response! Thanks!

SOURCE: Amp powers on but sub does not come on

I would double-check your RCA's on the amplifier. You should hear a thud if you unplug them. If not they are either not hooked up or defective.

SOURCE: how to wire 2 dvc subs to a orion 2150sx ? dont

what impedence are the voicecoils?
Dual 4 - Dual 2 - Dual 1 ??

Orion SX / GS / HCCA amp Wiring guide:

Orange = Right Positive
Black/ Orange = Right Negative
Yellow = Left Positive
Black/ Yellow = Left Negative
Blue = 1+1

Bridging of SX or HCCA Amps:
1. Use the Orange wire for Positive.
2 Use the Black/ Yellow wire for Negative
3. Push "in" the Mono Button
That amplifier is only 4ohm mono stable - so assuming the subs are dual 4 ohm voicecoils...

First wire both in Parallel Independently So each subwoofer is now a 2 ohm load. (combine + and + - and- on both subwoofers)

Now Take a positive on one voicecoil of sub #1 and attach to amplifier+(orange)

Take a - on that same subwoofer and attach it to a + on the OTHER subwoofer.

Finally, take a - from the second woofer to the amplifier -(black/yellow)

Now you have a 4 ohm load on your bridged channels.


Thanks for using FixYa - a FixYa rating is appreciated!!

I too have purchased the same receiver and have the same speakers. Did you get a good solution to this problem and how does it sound?

SOURCE: Hi. I got a Bose Acoustimass

Do you have any plan to use the Bose Acoustimass 20 sub/amp in it original form?
Please double check the pins count.
Popular Bose unit has 8,9 or 13 pins.
=====

A Bose third party vendor does sell a direct cable from the Bose Acoustimass 20 to two RCA and 1/8" stereo jack.
You can open the link HERE
Full site HERE
I'm sure you can find other cable vendor at a lower price.
======
I do not recommend you to open the Bose Acoustimass 20 and get the two set of wires out of the box.
It may cause damage to the casing.
======
On the DIN plug.
With notch / dimple facing the ground.
From let to right
1 = RED negative
2 = White negative
3 = RED positive
4 = White positive
5 center = un-use.

Please use an ohm meter to verify the resistance between1 to 4 and 2 to 4 before you start hooking up to the amp.

Please keep my posted on the project via email.
