    Your two postings about the subwoofer installation in your SQ5 were invaluable in my selection and installation of the VPSTX12 (shallow version) in my 2018 Q5 with the B&O system. Absolute perfect fit on all fronts. Happy to send you pics of the wiring harness I fabricated, with a factory connector so that no splicing was necessary -- total plug 'n play. One issue I've been having is the absense of signal to the subwoofer every 10 or uses. Cerwin Vega sent me a fix that required installing 47ohm/10 watt resistors across each output channel (left & right channel with the B&O system), which I did and it worked fine . . . so I thought. CV claims the issue is that the smart circuitry in the factory amplifier is looking for a resistance that would be present at all times with a passive speaker and that, absent that resistance, the factory amp self-protects by shutting off output to the subwoofer channel. Wonder if anyone else has experienced this issue.

    Alright, so I bought the CW normal depth sub for our SQ5 and just did the install based on this video. I'm relatively experienced in DIY auto projects (performance and audio) so figured this would be relatively simple based on this video.
    If you have the B&O system, there are a few things you have to do that aren't mentioned.
    1. The wire splicers that were recommended to tie into the factory sub harness are not perfect. They sit close together and need to be sealed off from each other to prevent feedback.
    2. You cannot simply connect the factory harness to the Kicker low line converter and then to the wires from the CW harness as shown in the final diagram. The Kicker that is linked needs to use RCA cables that connect to the RCA female inputs on the CW harness (and do not wire anything to the CW wires in the diagram in this video if you use RCA).
    3. The CW blue remote wire will need to be connected. I connected it to the remote wire coming off the Kicker low line converter which finally triggered the sub's amp to power on.
    4. I'm also already seeing a semi-frequent "sub does not turn on when the car is turned on" so not sure what I'll be doing, but I imagine I'm going to have to find a true 12v cigarette lighter-esque source to tap into that will be a sure trigger to power the CW internal amp on/off.
    5. And finally, I chose to just remove the spare tire altogether. We have AAA and will never use it, and I wanted the 250W RMS version vs the shallow mount which is listed at 150W RMS.

      I think you may misunderstand the wiring. The Cerwin Vega has a built in high to low converter. You will not need an external line converter that you are referencing. In addition, the high to low line converter is power sensing. That means when you power on the car with the line converter hooked up, it will take some of the power from the subwoofer lines and turn on the cerwin vega amplifier / subwoofer. Essentially, you do not need to hook up the blue line when you use the built in line converter. I wouldn't necessarily splice the cables in the same spot. as it does get bulky. I usually stagger them down the line a bit. The last note here is that you shouldn't hear any interference. The line run is so minimal, and the alternator is far enough away you shouldn't get any. If you do, it's likely a bad ground and you would need to ground it better. Great job getting the subwoofer going! I just wanted to clarify a few items. for you.

    • @tangentsdaily
      @tangentsdaily  Год назад

      ok... one more response... For the RMS / bass quality. There is a definite issue with all the Audi MMI systems, that bluetooth sounds like crap at high levels. While you may want more power, it definitely has enough power when tuned right. I am going to create a recommended settings video. I would #1 make sure that you are phased properly -- i had to phase the sub 180 to get it to sound better. Second I would make sure your eq on the cerwin vega is about 80 hz. Last if you are using bluetooth- I would turn on the EQ settings as it sounds loads better. I use bass boost on the iPhone. I would also make sure you don't have the Subwoofer setting maxed, and use the gain sparingly on the subwoofer itself. The subwoofer is going to max out on subwoofer output, but a few tweaks will make it sound better.

      @@tangentsdailythanks for the clarification. Your links in the description on both of your CW videos include one to the kicker converter. That theoretically makes sense if you don’t already know that the CW does the converting in the built-in amp, which I obviously don’t understand watching this. This will help immensely and I’ll likely just remove the oem connector coming from the oem amp altogether (we’ll have the car for a long time and I’ll just sell the car with the CW whenever that time comes). Thanks for replying @tangentsdaily, you do an awesome service making these videos.

    I am researching this now. I bought my wife a 22 Audi Q5 Sportback Prestige S-Line Black Optics Package "moth full". It has the B&O 19 speaker 755 watt 3D surround sound which sounds absolutely phenomenal however, I'd not balanced to be bass heavy. Previous Audi vehicles (cars) we have owned in the past with the B&O audio system have not had the 19 speaker cinematic sound quality but, were much more bass heavy.
    In VWs and other Audis utilizing the spare tire subwoofer I have seen a lot of writings, description of simply replacing the OEM DVC 8 ohm subwoofer with aftermarket ones from Polk, Kicker ect Reporting that the bass was noticeably louder and deeper with just the subwoofer swap.
    Have you seen any videos, writeups, post about this "swapping the OEM sub for a higher grade aftermarket sub" into the OEM box on an Audi Q5 ?
    I am not finding anything in searching.I do not want to wire up converters, locs, power wires ect. If the bass was just 20% louder and deeper, I believe it would be a perfect match for what I am looking to achieve.

      I did it at 180. It actually has to do more with the direction of the firing of the woofer. The best way to tell correct phase is the bass will be softer when it is out of phase because a reversed phase it will cancel out the existing bass from the midrange speakers in the doors.

    @mdube72 2 года назад +2

    Do you feel this is substantially better than the stock sub ? I have a 2018 SQ5 with the B&O. There is just no depth in the stock - no deep bass IMO. I am on the fence between a small powered sub that I know I will lose trunk space, or give this a go.

    • @tangentsdaily
      @tangentsdaily  2 года назад +1

      If you skip to 1:40 in the video, I go over the surface area of the speakers. While the B&O box says 2x100 -- it is actually dual voice coils in a single 6.5" subwoofer. Where as the Cerwin Vega is 11.3" and 600 watts RMS. Triple the power RMS, and double the surface area of the B&O system. Go with the shallow subwoofer noted in the description and you won't be disappointed. Yes it has way more bass than stock and the depth is absolutely there. I took a bit of time tuning the dials on the bass controller to balance the bass punch and the sound quality. An external subwoofer is not a bad idea, but are trunks are small enough, I just don't see a need to take up more space along with having a subwoofer that slides around... An external subwoofer would also require a line converter, a remote mount amp, and just is less clean than the Cerwin Vega. Don't forget to like and subscribe and thank you for stopping by!

      I bought the non amplified version and connected it directly. Bass sounded low, thought it didn’t work. I then installed a kicker key 500.1 and a 12” down fire kicker cvt. Sounded the same as the passive cerwin vega. The tuning helped out a lot. I think this tire sub would sound really good after it’s tuned. If you really want some had bass, I think a whole system overhaul would be the key.

    • @mdube72
      @mdube72 2 года назад +1

      I ended up taking the leap and purchases the CV spare tire sub. I also made sure that I ordered the shorter version and I can tell you it fits perfectly with no rubbing on the foldable cover area in the back. I have played around with the tuning - getting the gain set correctly and the bass boost took some tweaking over a few weeks to get it just right. I can tell you this is a significant difference over the stock B&O subwoofer and added exactly what I was looking for - some deeper, richer bass without the need to revamp my system. For the money, I think this was a great decision.

      You may have an issue with the Cerwin amp not turning on sometimes. I have noticed from time to time, that the sub will not "turn on" even though all the lights are green and the controller is lit up. From my understanding, the CV Input using High Level is 0.9V-12V. That’s not enough to support the B&O amp from cutting out after some start cycles. I haven't put in the Kicker 47KeyLOC, but still may do it
