Re: HELP installing self-powered bazooka with a monsoon (20VDUB)
That is the post. you want.
You only need the first page really. It may take a long time to load because of the pics. Anyway here is the post I had on there about the connections:
1) The color codes vary on the harness depending on model year apparently but the pin numbers don't. Anyway anyone doing this you should just go by the pin numbers in the plug.
Here are the pin codes for all the plugs on the Monsoon amp. Someone with a bentley manual should check these and let me know if anything is incorrect. I got these off another post a long time ago:
Green Amp Connector (Output to speakers, Not recommended you tap these, They are crossed over in the amp)
1 + LR Woofer
2 - LR Woofer
3 + RR Woofer
4 - RR Woofer
5 +LR Tweet
6 - LR Tweet
7 + RR Tweet
8 - RR Tweet
9 +LF Tweet
10 - RF Tweet
11 - LF Tweet
12 + RF Tweet
13 - LF Woofer
14 + LF Woofer
15 - RF Woofer
16 +RF Woofer
Gray Amp connector (Speaker level Input from HU) Most people tap the rear lines for Subs.
14 +LR
15 - LR
17 - RR
18 +RR
20 +LF
21 - LF
23 + RF
24 - RF
2) Amps or sub/amp combos like Basslink that have speaker level inputs dont need the line converter, you can just tap the speaker level wires in the gray plug and feed them to the speaker level inputs on the amp. Some may also not require the remote turnon lead because like the Monsoon amp they turn on automatically when a signal appears at the input.
3) Remote turnon: It may be a good idea to use a relay instead of powering the additional amp turnon directly from the cd changer harness. One guy accidentally shorted the wire and blew the turon circuit in his HU which would be a bummer.
A relay is simple to do: Get a 30 amp automotive relay. Hook it up in the following manner:
Relay coil A :Gray changer wire
Relay Coil B: Ground (I took it right from the - terminal on my subwoofer amp.)
Relay Common: +12V (I took it right from the + terminal on my subwoofer amp.)
Relay N.O. Terminal: Amp turnon terminal.
You dont have to do this... I just had the parts and it seemed like a wise thing to do.
4) An FYI: The grommet in the firewall is where the accelerator cable would normally be. Some of the 2.0s and other cars may still have an accelerator cable there. In that case you would need to find another place to get the wire through the firewall. All the cars with electronic throttles will have the plug although it might be hard to locate because of the insulation on both sides of the firewall..
