2015 Denali Subwoofer box

Brandon Sellers · March 24, 2015

I just got a new denali 1500. I need more bass and want to add two 10" subs under the backseat. I am curious how I connect the amp to the my link system and what should I be looking for. Also, really disappointed to learn no lift kit for a mageride suspension yet!! Great forum too!

Expensive, but awesome option:

woooooo! That's expensive with no amp. I was going to do some Rockford Fosgate Power with an amp. I am just worried about how I wire this up into the radio. I have never had the my link or anything like it. Thanks!

No prob.

I'm scared to touch the OEM radio, lol. Someday I'll find this stealth box with an amp, and then get it all figured out.

Brandon Sellers · March 24, 2015

yes. that's what I am scared of is the radio and I am looking for advice on that. may just have to take it to a stereo shop.

As for signal I recommend using a proper crossover that will take a signal and clean it up before it goes to the amp. Dont tap into any power wires . Run everything to be stand alone. Remember there are a host of low voltage class 2 data lines that you can smoke with a simple test light. If you dont know what your doing . Dont. Its that easy to burn a module or short something.

The Denali features the premium Bose system. Just mentioning this as unless you know exactly what your doing, you best seek out the proper technical advice before trying to add on to the Bose system.

do you have the bass turned all the way up on the settings? I think there is plenty of bass, def not 2 10s bass but enough to feel it in your seat

If I'm not mistaken the factory amp is behind the rear seat, and sub is under the console, one would think you could tao into the wires feeding the factory amp. I would leave it to a pro, but that's where I would think to start

I personally wouldn't tap into any Bose speaker wiring for an aftermarket signal source. They tailor their amp outputs with a lot of signal processing to perform for that specific speaker in the enclosure it was designed for. Your low volume bass will probably result in extermely loud bass in an aftermarket system that'll taper off quickly and just sound awkward.

If you want to do it right, at a cost, it is hard to beat any JL audio product for the loaded enclosure that fits the vehicle. As for wiring it up from there, you may be better off tapping into the head unit to bose amp signal line, sending it through a crossover, then running that to your amp.

The problem with the Bose system is that there isn't an analog signal from the HU to the Bose amp. It's all digital. The Bose amp has a D/A converter inside of it.

This post over at Do It Yourself Mobile Audio (DIYMA) explains what's going on and how to do it right:
