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. ~Jason

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 ------------- Claude B.

The Basslink is an amplified sub woofer so it doesn't matter whether you tap in before or after the Infinity amp.

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.

DYohn, I'm thinking that the Basslink takes speaker and low level input whichever you wanted to use. Unless I'm mistaken, no problem but I figure if it's speaker wires coming off the back of the radio, he can tap in to the speaker wires at the back of the radio. Is line level the same as low level? (Rca jacks). If I';m mistaken again no problem. I'm hear to learn also.

Harvey you are 100% correct, but since he is connecting it to an amplified factory system, he won't have any RCA's at the HU to use, so the easiest thing to do is use the speaker level signals after the amp. That's what the original question asked. Adapting OEM line-level wires to RCA's is a PAIN!

Will the Basslink work with an already amplified signal? Because hooking the BL after the amp you will be sending an amplified signal into another amplifier. Sounds like a lot of noise waiting to happen. Thats why I figured you could wire the Basslink before the factory amp using whatever speaker wire you wanted.

The Infinity Basslink system is designed to use either a line-level input from a pre amp OR a speaker level amplified signal from an amplifier. In a factory system with external amplifiers, you CANNOT easily get to the line-level signal, which is what the head unit is sending to the amplifiers. You have very easy access to the speaker-level signals, either at the speaker terminals or at the amplifier output. This is the best, safest way to connect any aftermarket amplifiers, Basslink or not, to a factory system. Yes it can be noisy. But not as noisy as if you try to solder RCA cables into a factory wired line-level system and don't know EXACTLY how to do it before you start..

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... ------------- Claude B.

What? All high level to low level convertors take a very small amount of power from the speaker lead (like a sample), it then takes this sample and converts it into a low level signal. You will not notice a difference in sound from your speakers with it connected.
