This is my first post but I've been lurking for a few months. I traded in my 95 yukon for my new to me 08 Sequoia Limited 4X4. It's a HUGE upgrade and I love it, from the power to the ride quality. I like the JBL thats in it but I need something louder. I had a big system in my yukon but I'm looking for my SQ over pure power on this one.

I already have a Kenwood DNX7180 GPS Nav unit and 2 sets of Infinity Kappa 6.5 component sets. I just need a 5 channel amp and sub then I should be ready to tear into the Beast...

Has anyone else installed an aftermarket HU in there JBL Sequoia? if so are there any issues getting the steering controls to work or intergrading into the JBL amp? <- only if I install it now otherwise I'm removing the factory amp.

thanks in advance.
