Default Subwoofer in the A8 opinions

The sound system in my A8 is wonderful and all that, but I don't believe I've owned a vehicle without putting a sub in it.

SO, my question to all of you is does anyone have any tips or advice or warnings from past experiences when installing a subwoofer and amp?

I'm quite curious myself, been thinking about removing the rear deck sub and adding an after market sub with an amp.

So do you think it would benefit from it, or is it just a tradition of yours?

Which sound system do you have,

I love the sound from the Bose setup and to add a sub would ruin the sound and make it too boomy. Added to that the trunk of the A8 is heavily insulated and some distance from the drivers seat , so you would struggle to hear it in the cabin.

To put it simply, I don't believe the A8 needs a sub, after all its audio system was designed specifically for the car and is not some generic off the shelf system installed in many different brands.

If it were me, then I would just stick with the Bose setup if thats what you have because adding a sub is a technical nightmare anyway.

You know the slogan from the audiophile world, Bose no highs or lows. Stock Bose does have decent bass at lower to moderate levels but cannot reproduce those at higher volumes. I have a acoustic suspension 12 inch JL Audio W3V3 with an Alpine 500 Watt RMS mono amp. The sub is tapped into the Bose sub with a line level adapter. I also have a bass **** so I can turn it up or down on the fly with different types of music. It rocks. My philosophy is to tune down the lows on the bose system so they don't have to reproduce lows as little as possible. The mid and highs sound cleaner that way. Then you get a thumping sub to augment and for a stock system + sub, it sounds awesome. I'm not going to win any stereo contest but I'm happy with it. I also took out the ski boot so it has kind of a port for the sub. It does make a difference between having the arm rest up or down. As an added bonus, you can stow away tablets and electronics in the trunk though the space without opening the trunk when leaving the car in a parking lot.

I have always added a sub as well. I had two previous Alpine Type R subs but the rubber would delaminate like clock work every 3 years. This is my first run with JL audio and let me tell you, the sound difference is dramatic. I will say I upgraded the amp from 300 to 500 watts when I went with the JL Audio, so there is that factor. I think if I would have went with either the V6 or V7, it would have out punted the coverage of the Bose system by far.

That's what I needed to hear.

Yes, I have the Bose system, and it is excellent and works great, I think I'm just getting bored and looking to do something to The Silver Fox. I don't listen to much rap or bass heavy music, just wanted to add a MTX T8000 10" for a nice sound quality bass, but you're right. Really not necessary.

B/O system sounds great, piped in some music from my note2 through the AMI with enhanced bass settings on the phone player. Actually had the rearview mirror shaking. Rear window shade rattles at certain frequencies.
I agree with TSHONG as far as toning down the bass in the system if adding an aftermarket sub. Make sure to set a proper crossover point to let the subwoofer do its job.

Haha! So true Mishar. I protect my ears at work, wearing earplugs and even ear muffs over them mostly the whole day. Loud music and loud pipes are a thing of the past.

Jake, those are perfect. One can pretend he is listening to the music while trying to read the speakers mouth.

I have the standard Bose system and today set all the levels to the middle and really cranked it up. Quite how anyone feels that the bass is in anyway lacking must be both deaf as a post and completely numb! The volume level was not even full but it was verging on uncomfortable. The bass was shaking the rear view mirror ghetto style, and there was no discernible distortion at all.

You sure your systems are working properly?

I don't know that my B&O system is working correctly. Had the dealer remove all panels and check all speakers including sub.. They only found a defective passenger front sub. I doubt that's the only issue but they can't find anything else wrong. Go figure.

Why didn't I think of this?!
Although unless the kids are with me I don't think I could reach the ski sack door!
Thanks, TS or Hong (whichever you like to be called)

I am a Tom as well. I use this when I have my nieces with me and they bring their tablets or laptops with them. If we go out to dinner or some where public, we just use the opening so there is no temptation for anyone. Works quite well.

My opinion
The standard bose set up for me was ok but having always installed car audio systems in previous cars it did not have the definition that I wanted and the kick that i like.
I changed the complete system and built a sub in the back side of the spare wheel. This whole thing is not worth doing if you do not have patience as the A8 is the hardest car I have ever done and a pain in the ***. The easier option will be as posted above and just add a sub and amp. The Bose sub is not good at all but for some it is adequate :-)

I thought about it but I knew it would be too much for me handle. I think the cost/benefit ration would be way out of wack. I think the B/O system with and added sub would be the ticket.
