A:Answer Hey there, RacerX! Thanks for reaching out about having our Autotechs install your powered sub. We would charge a $5.00 materials fee, $99.99 for the amplifier installation, and $24.99 in custom labor to install the line output converter, which costs about $14.99. Of course, without seeing the vehicle in person, this is only an estimate. I'd recommend calling 1-800-433-5778 or visiting www.geeksquad.com to set aside some time during which our Autotechs could take a closer look for you.
