Here is an example link, but there are others out there…. https://www.diymobileaudio.com/threa...ftware.359418/ Edit: One other thing, my tune file won't sound right in your car for among other reasons, the time alignment will be off. So at a minimum, once you have converted the signal routing to your setup, don't forget to adjust the time alignment values to your speaker locations. Using the tape measure method should be good enough, which is what I used to set the time alignment for my car.

Jmciver. Did you ever add the trunk sub? This has been amazing thread to follow and just wondering as I have the same set up but kept the factory HK 8” in my 2018 G30. The 8” are good midbass but I’m definitely missing low frequency depending on music content.

However, I still want better bass to fill out the sound in my system, so a trunk sub is still on the menu and most likely will be a late Fall/early winter project. All the connections are ready so I literally just need to "plug it in"….

If you don’t mind a question on the use of sound deadening to this level.
Did it alter the M3 in terms of character ? No doubt far better for audio but did it dampen down of the noise of the M3 from a driving point of view ? |

Hi, I will put up a for sale thread but I will be selling this amp that I had for a year. Will be selling with the helix sdmi 25 most converter.
Will also supply the custom tune file. |

[QUOTE=johnung;29641128]A LOC is needed but that’s the beauty of the AudioControl because it has a LOC built-in. Installed it right on top of the toolbox in the right trunk alcove.

So a small update to this project regarding the trunk sub…. For a myriad of reasons that I won’t bore you with, the trunk sub portion of this project has stalled. I also went back and forth A LOT over what sub/amp/enclosure combo I wanted to go with. In the end, I decided to go for a “better” amp, with a “modest” sub and enclosure. There are tons of professional acoustic opinions on this and I decided to go with the opinion that a good amp can make “average” speakers sound great when setup and tuned properly. A contributing variable for me is cost as we all know audio componants can vary widely with cost - but more expensive equipment/components does not always equate to better sound.
I also went back and forth on the power level I wanted to use: 300 watts vs 500 watts. Many go with a 500 watt trunk sub setup. I actually thought this was overkill for the amount of bass I thought I wanted. Although, some will say that the trunk in the F3x/F8x is sealed so well that it is better to use a 500 watt setup for a better bass experience. I was going to go with a 300 watt setup (which would have been cheaper), but after a few Black Friday sales I came across (the amp in particular), I decided to go with a 500 watt trunk sub setup … So after all that, I am going with the following setup for my trunk sub… Amp: JL Audio RD500/1 Sub: NVX VSW102v2 10” sub Enclosure: Visual Ice F30 trunk enclosure The long pole in the tent is the enclosure, which I am still waiting for. In the interim, I have the sub and amp. I also installed/wired the amp in my car so when the enclosure comes in, all I literally have to do is plug it in. After reading about this sub, including looking at the T/S specs, I am looking forward to how it performs in my setup. This sub choice definitely falls in the “less expensive” category. But if it doesn’t work out, I did not lose much $$ and my enclosure will still work with my next sub choice, a JL Audio 10W3v3-2 10” sub.

Great thread and nice work! I just finally installed the same subs (Audison) and amp in my G80. Had the amo before in my G20 to get to know it. Can I ask a few questions: When I turn the volume to about 75%, the subs starting to make a clunking noise, like they are hitting something (thinkikg clipping, maybe my power cables suck). I had the exact same with my HK woofers in the G20, so it must be a setting I guess. Did you encounter that issue? I turned off all the bass expanders and went with the virtual routing. I understand that the G2x HK with RAM has crossovers set that you cant take out. Is the F80 More customizable? |

What's happening is that they've run out of excursion. Too little excursion capability is the main limitation of the OEM woofers and most replacement woofers, including Audison. One reason why I recommend the Earthquake is that they have the highest excursion of any drop in replacement woofer.

I purposely got the Audisons, based on their specs, to be more of a mid-bass speaker, when combined and tuned with my trunk sub. However, I was pleasantly surprised with how well the Audisons did sound, even though they could not go too low, while I waited to complete my trunk sub setup. If I did not plan to run a trunk sub, I would have gone with the Earthquakes for their better low end response. As far as the F8x HK being more customizable than the G8x, I am not sure. But with the F8x HK system, I know the sound signal coming from the headunit is “unmolested”, so to speak, which allows me to take full advantage of the DSP features in the Match amp. Although, I thought that the interface harness between the RAM module and the Match amp was designed in a way to give you a clean signal for the Match amp to be able to process?

When I tuned the underseat woofers (i.e. EQ’ed them) together with the rest of the system, I lowered the gain a bit on the two woofer channels to help prevent the distortion you described (and also match the target house curve I was shooting for). I set my crossover at 35 Hz on the Audisons which seems to work well. I also use the URC3 remote, which also gives me some additional volume control over the underseat woofers. As I said before, I don’t use SubXpander which was the biggest culprit for that type of low end distortion.
Lots of different ways you can adjust the low end frequencies for good sound without distortion. But the Audison woofers do ultimately have thier limits…

The Audisons run out of response and excursion at 50Hz, so content below that is going to stress them. SubXpander creates a tone an octave down from the original, so if the bass or kick drum is at 40-60Hz it's going to add content at 20-30Hz. That's going to result in over-excursion and high distortion from both the speaker and amp. Output at those frequencies is down -10 to -20dB, so you won't hear it anyway.

Do you have a rough model for the underseat enclosures size and it’s extension into the sills ? I can’t work out if they are loosely sealed or an ib setup type loading. Interesting the Xmax specs on the earthquakes at 22mm ( wonder if this is real verse an xmech value ) 7mm ish for most drop in replacement. 7 mm obviously not a lot of travel for below 50 hz at moderate volumes. |

When I measured the response of mine it came out to the equivalent of a 0.6 cu ft sealed box with Ql of 3, so they're pretty lossy. Qtc measured right at 1.000, which is right where you want it in a car. I'm sure that's not exact, but it's close enough for driver modeling. I don't have Earthquakes myself, listening to only Classic Rock I don't have the need, but I have no reason to doubt the 23mm Xmax. 7mm is OK with the response you're going to get with the typical 50Hz Fs of replacement 'upgrades' (the OEM Hi-Fi Fs is 51Hz.), but to take advantage of the 30Hz Fs of the Earthquake you need that 23mm.

Just planning a build to replace speakers / amp and underset enclosures and try and do a one box most/dsp/amp solution. ( 8.1.1 ) Reason for asking about the Xmax was I have an oldish Boston Acoustics SPG555 sub that has 22mm Xmax but has one of the largest surrounds I’ve seen with Xmech at 49mm. 23mm seems quite an achievement on such a slim driver. I’m heading more 7mm way with 50-60hz crossover My f80 is uk spec and came with basic audio with 4x100mm mid basses and two 6.5 inch underseat woofers run at 25 watts x4 . It’s quite underwhelming and suspect it’s running a Bose like house curve.( boosted mid bass and treble ) This has been a great thread for info |

I'd keep the underseat enclosures, just load them with standard spec eights. They're plenty good enough if high passed at 60Hz.
On the subject of the mids, I just came across these. https://products.peerless-audio.com/...-115N25AL01-04 They spec out better than any other midbasses I've found, including the ridiculously priced Focal. I'm inclined to try a pair, at less than $40 USD it's not a major gamble. That will have to wait for spring for me, I don't have a heated garage to work in. They're not drop in, you'll have to finagle them, maybe even get a grille with more clearance, but it's worth the work to save major coin and get better results than the so-called upgrades that aren't even as good as stock.
