warranty.  Should you choose to install it yourself we will still give you 

one-year parts and labor warranty.  To activate your warranty, you need 

to FILL OUT AND SEND IN YOUR WARRANTY CARD!  

We also recommend that you save your invoice or sales slip as proof of 

installation and ownership.  Not only is it necessary for warranty purpos-

es, but should your LC7 “walk away” one day while your car is parked at 

your local latte’ stand, you will find insurance companies very unforgiv-

ing without proof of purchase.

Quick Installation Information

For those of you short on time but high on ambition, we offer the fol-

lowing section to speed up your installation of the LC7: 

1. Physically mount the LC7 in a location that keeps it away from 

soda spills, food crumbs, and curious fingers.  You will want to select a 

location that allows you access to the level controls.  In many cases you 

can find factory speaker leads in the rear of the vehicle that are easy to 

access.

2. The LC7 needs to be installed in the signal path between your OEM 

source unit or factory-installed amplifier(s) and an aftermarket external 

amplifier and/or processor(s).  Locate the speaker wires that are coming 

from your factory source unit and/or amplifier and connect them to the 

speaker-level inputs on your LC7.

3. Connect the Output RCA connectors to cables that run to your after-

market external signal processors and/or amplifiers. If this is not obvious 

to you, quickly pack up your LC7 and run to your nearest authorized 

AudioControl dealer to have them perform the installation.  You will 

thank us later.

4. C12 power, ground, and remote turn-on (if applicable).

5. Level match your LC7 to your source and amplifiers.

Note:

 You will want to turn the gains DOWN on your aftermarket am-

plifiers to maximize your systems performance and minimize any HISS.
