Very clean, that looks like exactly what I want to do. How did you hook up the amp, did you leave the sock amp hooked up?

 

Yes, the stock amp is still hooked up, just the wires to the sub are no longer connected since they are now running off my other amp. I have an after market radio in there so I just ran the normal rca and remote wire back to the amp and then just grounded and power wires right to the back where the battery is. If you use the factory radio, you just need an adaptor plug that turns the wires into rca's and then you just plug the rca's into the amp and run the new speaker wire and you are all set. If you go to any local audio shop they will know what I am talking about when you want to add an amp to a factory unit. Yes, that is what I like most about mine is it looks like it came with the car.

 

According to a sticky about putting a sub in the back, the factory head unit is rca back to the factory amp, so you can cut the wires before the factory amp and you have rca without a converter. As long as you don't mind sniping a couple of wires...which if you're removing panels and swapping speakers, i'm sure a pair of side cutters shouldn't scare anyone

Thanks for all the good info. Definitely like the idea of not taking up storage space.

 

Is this the same for the Pioneer setup?

 

I understand what you are saying, but I don't recall there any rca's going into the amp. Unless you know what the remote turn on is from all the wires going into the amp, you need to have something to be able to turn on the other amp if you add one. That is why its easier to use a line out converter with trigger remote. Maybe you are just talking about using everything factory and just replacing the sub. I would recommend adding an amp just for the sub at this time, since it sucks to take all the panels off.
