hey guys ima about to install components in my back rear deck but hears the thing i already have components up front with a alpine pdx 4 channel amp only using two and its all set up already but now im ready to throw some in the back and im kinda confused on how much the shop would charge me i believe he said a hundred just to throw in the back components is this to much considered the amp is already installed

 

No not at all, considering all the steps needs to go through on TL.

remove the back seat (side).
remove side pillars.
remove rear deck
remove rear speakers

run new speaker wire or tap into existing one.
build a plate for components or modify rear deck for the tweeter placement

reinstall everything in reverse order.

sounds like it is not a big deal and it is not but it is time consuming.

note: if rear deck is not reinstalled correctly. rattles may apear.

hope this helps.

 

For the amount of work, a hundred dollars is not bad, you can do it yourself.

 

Honestly, I would amp the stock speakers first and see if you want to go aftermarket. You would be surprised how much better they sound amped. Besides, they're usually used as fill, unless you're always carrying passengers back there.
