i just got a 2007 HHR LS for my graduation gift and got two 12in L7's a pioneer 9883 aftermarket head unit and a 1700 watt kenwood amp. But i dont know which GMOS LAN to use. If anyone knows which one to use it would be helpful.

 

Depends on a few things do you have onstar and the upgraded sound system?
If so you need the LANSTAR4 if not then the 3 from soundgate.
Metra is GMOSLan 3 for nonupgraded and 4 is the upgraded.

 

Lan 3, we will call you when it comes in the store, i just hardwired mine and it works fine. you drive the black on black correct.

 

yes i do, are you the guy from custom sounds on san pedro with the HHR?

 

yes i am, did you check it out in the back the other day?

 

Cool, Custom Sounds here in St. Louis did my set-up!

 

no i didnt. you should post a pic of it.
