In my trunk.... I have grown accustomed to building a nice subwoofer enclosure and wiring everything into my car myself. Now I have a '15 is250 (non ml). I spoke with many people at the dealership, and the problem I seem to have run into is multiplexing... Basically, one wire sends like 10 different signals. I dont want to really tear into anything until I can be sure I'm not going to screw this up. I'm not even looking to add a ton of bass... Maybe 1 12". So, does anyone know what I might need as far as supplies, or where I might go (around San Antonio)?

 

I took it to a shop and they installed an old 12 inch alpine type X i had. Its pretty cool you can control how hard it bumps from the radio settings. Turn up bass as loud as you want it to go.

 

Did they charge for any special hardware? Or do you know if the radio is just plug and play back there?

 

I have no idea i just dropped it off picked up and had bass.
