Infinity Basslink in 03 Dodge Ram

Hello Everyone.

I have tried to search for the answer to my question but have have received mixed results. 

Heres what i am trying to accomplish.  My uncle has a 03 Dodge Ram Single Cab with the Infinity Sound System It has 7 speakers 2 in the door 2 in the rear panels, and 3 in the dash.  He's wanting to put an Infinity Basslink in the Truck while keeping all of the Stock System.  I have done a few install's myself so i am trying to help him out somewhat.

Questions?

1.  Will we tap into the speaker wire's to got o the Basslink before or after the Infinity Amp?

2.  The Instructions that came with the Basslink mention taping into all 4 channels if avaliable.  IS this really needed or can we get by with just tapping into the rear speaker signals?

3.  Can i tap into the turn-on lead on the stock infinity amp for the basslink turn-on (remote) wire?

4.  Which  wire's will i tap into and where woudl the best place to splice these wire at?

Here's The  Speaker wire's that i have found so far there was no polarity listed so i am thinking that the first wires are positive and the 2nd wire is neagitive.  please correct me if i am wrong.

LF Speaker  light GREEN/ red   and   GREEN/ green

RF Speaker light blue/purple and blue/black

LR Speaker WHITE/ Red and WHITE/ Black

RR Speaker Tan/Purple and Tan/Black 

Thank you everyone in Advance.

1.  After.

2.  You can use just the rear channels.

3.  Yes, assuming you can identify that wiore.  Use a voltmeter and test each wire by turning the key on and off and see which one powers up with the key.

4.  Assuming you mean speaker wires, splice anywhere that is readily accesable and can be easily hidden.

yes you can only stick-it to the rear next to the speackers, they said to the 4 speakers in case that you want to fade front and rear it will not fade the base-link!

and you don't need a wire for the turn-on remote cuz it will do it by it's self because it will feel the signal of the rear speaker, and when it got no signal it will go off after 5 min.

and to found out the -,+ i use a 9 volt bat. touch the 2 wire and with the + of the batery in the good side the  speaker will pop-out! that's the way i found!!!

i just install one in a ford f-150     pretty good

Yes it does.  The speaker inputs on the Basslink system need a speaker level signal to function.  This means after the amp.  Before the amp the signal is line level.

the base-link have a interface made for that!

if  you get connect to the speakers wires it will only take the signal from it with-out talking out some power from your speakers!!!!

it's built for that...
