I did my 2016 bose system as well. Tapped the bose subwoofer outputs. The signal output is a nice clean low frequency range. Placed a single JL Audio 13tw5 under the passenger side rear seat (box from subthump). Used a Audio control LC2i signal processor from the sub signal so that I could add a bass knob upfront (located in the top of the map holder beside the driver's right leg and can easily control the loudness of the bass. You can not see the knob unless you know it is there. Amp is a JL 500 HD. Both the LC2i and amp are located under the driver side back seat but can be reached for adjustments if needed along the back/floorboard area. Luckily able to mount it where it does not affect storage space. Super happy with sound and most think I have upgraded the entire system not just adding a sub. It truly sounds like a different system with the sub.

Yes here are a couple... One of the amp set up on the driver side... The other is the subthump box with the JL 13tw5. . The amp is set under the back seat on driver side towards the back wall at an angle that allows the seat to raise and lower but also allows me to easily make adjustments if needed.

Sweet^^ So this maybe a better alternative to the Kicker Soundgate system ?? I love to add a rear sub to my Bose system. Price wise which would be more economical??

I don't know the Kicker price but the prices I paid were approximately as follows:

500 watt JL Audio amp $450

JL Audio 13tw5-3ohm (discontinued v2 in place) - $500

Audio control lc2i around - $100

Wire and smalls accessories - $100

Subthump box - $170 with shipping and extra costs. Without any installation costs materials would be around - $1300 to $1350 plus/minus

Thank you for the price list! Definitely helps us non-electronic folk with decisions regarding system set-ups!

You bet... And just as an FYI... You may be able to get a better deal on an amp (I bought my amp and sub several years ago) ...On the sub I want a good size without taking up too much space (.8 cubic ft) so 13.5" sub was one of the few low profiles a few years ago... I think JL has since come out with some lower profile flat style smaller subs as well(10/12). I also wanted something for a sealed enclosure as I listen to a lot of 80s and 90s rock music and the bass drum is hard to sound good, too me, on a ported system.

Any issue with the Active Noise Cancelling on the Denali?  you have 6.2L engine?

 

Thanks.

None at all... I cut the wire (purple and blue? -crankshaft replicating wire) that sends signal to the bose AMP that tells it to engage the noise cancelling. I posted somewhere else the details of the which sometime back... I just don't remember all the details.

If your amp has a crossover I'd use the factory high from a full range door speaker and let the amp do the frequency filtering. You could try the sub but it may not be the most efficient signal for your new sub. You might end up clipping the top end of what the new sub can do. But to be honest I haven't messed with the Bose system on this gen of truck, only the last gen. The doors may not have the lower frequency on the Bose system like the non-Bose system does.

There isn't a full range signal available anywhere I'm the vehicle with Bose.   That's what. Jl Audio Clean sweep or anyother summing device.  It takes all the inputs fr the head unit combines them for a true Full range signal.  If you tag a door, even the sub after the radio the signal has been processed that little Fosgate 5 channel already has the.fromt read and sub crossover points permanently set.   

Hope that makes sense.  Obviously the factory sub isn't playing any 35 hz tones,. The JL 8 will play that low tho.   But what's the point of the signal its recieving is bandpassed between 40hz

and 220hz

Anybody know what type of terminal this is? The connector it belongs to is for the Bose amp connector X1. 2015 Silverado 1500. Tried GT 280 female, but it won`t fit in the connector.

      Winter Returned

      .30” of rain all month and it’s been weeks since that. “Mowed” our two properties today for the first time since July 2nd. It only took 30 minutes because all I had to do was level some weeds and saplings in a few problem areas. Everything else is dead.

      Shift to Park Message Warranty Claim

      By tjonesdfw · Posted

      Dealer reported a failed shifter module assembly so the whole shifter is getting replaced. Yet another premature repair… up to $12,000+ in extended warranty payout in only 5 years and 80,000 miles!

      2021 with Intermittent AC Cooling Issues

      According to the dealer it’s an internal leak/failure of the compressor.  Again, another failure that shouldn’t happen at only 5 years and 80k miles.  For some reason the compressors must be hard to come by right now, because the truck’s been at the dealer almost a week and they just located a compressor at another dealer several states away today.  We’ll see if this fixes the issue.

      Brake Bleed Procedure

      By needafix · Posted

      I'm not sure if this should be a reply on this thread or a new topic, let me know if it's out of place. This my first post. Thanks 85077522 - ACDelco GM Genuine Parts Brake Master Cylinders. Anyone else had to replace this brake master cylinder yet. I didn't do any brake work, it looks like new parts and I've had the truck for about 4k miles. When it started to throw codes I did the calibrations with a bidirectional scanner and got the codes to clear but they came back so i did the routine; base bleed, automated bleed and final base bleed. All that with Bosch ES16-32N fluid (please look it up). That seemed to fix it but 100ish miles later it failed again so I ran the same process but with a pressure bleeder this time and got the same results, fixed for 100ish miles. The original fluid looked bad and I thought I got most of it out. The codes; P25A2, C05B0-00, C2A1B. I can get them to clear but not for long. The C05B0 indicates a leak in the front circuit (which is bone dry) so I'm thinking of doing the bleed process on that front again today and I don't know if that's taboo to just do the front but at this point it seems like it's worth the try anyway. The new master cylinder/module unit is supposed to get here today. But now I'm pretty much convinced this install is over my head. I've called several shops and some mobile guys that I know but this thing is like radio active material scary wise. I did get 2 local shops say they should be able to do it, one says he has the SPS2 programing capability. And with the battery disconnected is there supposed to be pedal resistance, mine is to the floor, then if I pump it I can get some resistance.

      I wasn’t commenting on your post. Certainly wasn’t arguing. I was making an observation on my long term experience with supposedly proper length of driving for proper heat cycles. Works for me. Although I have seen water or vapor come out of exhaust when vehicles weren’t run very long and shut off. It’s very humid in the morning. Then hot and humid.
