21 Malibu - Non-Bose System-Factory Head Unit- NS-A 1200 Insignia Class D Amp- 2- Z-Stat 12's in a closed enclosure.

I bought a harness and the wave-link device from LLJ Customs for the car and got it all hooked up, but the subs sound hollow. I have played with the both the gains for the wave-link and the amp, but it just acts like it knows it is supposed to be hitting, but there is no umph in the bass if that makes any sense. The yellow clip light isn't lighting up to signal it is cutting out at the Wave-Link and the leds, fuses, etc on the amp all say good to go.

LLJ sent a ANC terminator plug, but I can not for the life of me find where it goes. I looked where the amp is, under both sides of the center console, all behind the carpet and I can't find anything that even resembles the plug. Anyone know where this is? I was told it is possible the ANC is messing with the bass levels(not sure if accurate or not).

I have the remote out from the wave-link running to the remote in on the amp. I am guessing that is correct?

I know the subs/amp are good as they were doing very well in the car I took them out of and I even had the amp tested today and it is pushing as advertised outside of the car. I wasn't able to test inside.

The sound just is not there. I get low rumble and the occasional hollow thump, but that is it.

Thanks for any help!

I too order the ANC from LLJ customs and also could not find where to plug it in. I ended up finding all of the microphones and disconnecting them from the factory plugs. You'll find youtube videos of people cutting wires either at the microphone side, or you'll find people cutting wires at the audio processing side under the dash. Before I disconnected the ANC mics I would only get a low rumble when the volume was low or the stereo was off. Looks like LLJ changed who they use for the RCA converter but my opinion you need to look at the ANC. Hope this helps :)

My car is a 20 Malibu RS - Non-Bose System-Factory Head Unit running a SKAR 1000W and 2 12"W3V2 JL audio Subs.

Thanks for the info! I'm glad to know it probably is the ANC thing. I am going to look around for it more over the holiday I guess. I may have to resort to unplugging the mics as well. I don't want to cut anything. I have what looks like 3 in mine (2 in the back and 1 in the middle of the roof). Do all 3 need to be unplugged?
Thanks again.

I just learned about the third ANC microphone last week. It's in the back, just above the rear window, in the center.
I'm not gonna cut wires or take apart the trim, so I just stuck vinyl buttons over the microphone. They are sold as cabinet bumpers or rubber feet for small appliances.

I swear it made a difference once the microphone is covered.
I covered the two mic's in front last year. Up til now, I always thought the rear speakers sounded different somehow from the front.
I have Kickers in the back and Dayton Audio Ultra-efficient in the front, so I thought it was the different brands sounding different. WRONG!
Good quality speakers have a neutral sound, so they don't sound much different from brand to brand. Once I covered up the rear microphone,
the front & back sound much more similar, and slightly improved highs and lows overall.

Active Noise Cancellation makes the car sound quieter, but it is NOT something audiophiles want! There's no free lunch. ANC reduces engine noise but also reduces any music tones that are similar in frequency to the car sounds! The result is a weird artificial sound to people who pay attention to their music.

Also wanted to mention I replaced the front pillar tweeters with the $8 Power Acoustik tweeters sold at Wal-Mart. They are a good match to the Dayton Audio Ultra's, they are very efficient (97 db SPW at one watt). In fact I turn down the high freq. setting now, even tho as an older guy I hear less high frequencies than young folks.
The Power Acoustik tweeters really sound better than the stock tweeters. The factory speakers in the Malibu were designed for low cost and not much else!
