Is all this correct for an install? 2008 Double Cab with JBL.

 

Thanks for the info. Yes, I did compare prices with crutchfield.

20 Bucks cheaper through Amazon. Granted you don't get the support like Crutchfield does. Same stereo is 199 through crutchfield.

And I have heard the Scoshe kit "fits" better. I only found the Metra Kit on crutchfields bundles.

 

Yeah, I priced everything out exact....

 

Thanks for the help Rock Lobster.
