Audio upgrade options

[zrk]

That price tag though, $2500. Thats how much my full audio upgrade equipment is costing.

That is a full audio upgrade.

No, its just adding a powered sub and retuning the factory speakers.

The factory speakers are not bad, it the terrible amp and EQ. Oemaudioplus addresses this with their amp/dsp which has been specifically tuned for our cars along with the integrated subwoofer. Anyone can throw a higher power amp and aftermarket speakers in, but tuning a DSP specific to our cars is where OEMAudio plus invested the time and money. I really don‘t think it’s a bad price. If you we’re to buy a decent 7-8 channel amp with full DSP capabilities your easily looking at $1500+

Throw in the interrelated sub and all OEM harnesses, so no splicing, and then a professional tuner to dial everything in and your over $2500.

Its all about the DSP amp, and tunING. And then having the right equipment and knowledge to dial it in.

It would be interesting to see the actual tuning. They do not separately tune every speaker which is what it typically done with active crossovers and external DSP. They would be tuning the individual channels which would be 5 channels, possibly 7 if they still use the factory woofers and their separate subwoofer. The factory "subwoofer" is actually a woofer since it probably has to crossover relatively high for the door speakers. (My plan for the crossover will be between 150 and 200 hz. and my removable subwoofer at 60 Hz.) They can equalize the output of the speaker channels and time align for better "imaging / staging". I personally would agree with Metal.

The 2 OE subs are deleted / bypassed in the OEM Audio + application which is a big disappointment to me...

I would have rather kept them in the system adding crossovers with some DSP applied to have them operate as mid-bass speakers...

FYI....

OEM Audio+ updated their website which goes into some greater detail and specs about their system for the Supra....

I really like their clean installation I agree with you that using the factory woofers would be preferable as a true woofer and added unit as a subwoofer but I suspect that would have required significant modification to the cabinet as you have described. Also added more cost as additional amplification would be necessary.

I am using the Mobridge unit for 5 channels, the high output to the woofers and the subwoofer output to the removable subwoofer. I remove the subwoofer when going to the track.

Aside from adding crossovers, the only modification which would have been needed would be to add 2 exhaust ports to the narrow rear panel of OE woofers as I outlined in my thread I posted awhile ago ...

OEM Audio never took this into consideration while developing thier system assuming the 2 rear OE woofers were not very good...

Had they done so I think they would approached things a bit differently....

Well.... If I do decide to go this route, I could always convert the woofer holes into storage bins. Seems a shame after doing Tadda's mods though.

Your price would be a very high end high powered amp with a large sub channel. You can get small form factor 7-8 channel amps with DSP that do around 400-500w for $300-600 no problem. They're claiming 6w per channel on theirs vs 40-60w on aftermarket units but their amp is very small.

The most you can process is per channel and since this is hooking up to an OEM harness that means the OE system is combing multiple speakers per channel. That's not a big deal though as you could easily just run DSP on the whole system with no individual channel work and make an improvement. OE systems nowadays use center channels to get each seat a pseudo center image which makes a big mess. If they even have 1 channel to LF, 1 to RF and 1 to center then you have more than you need to make big corrections.

Personally, I would never want midbass speakers behind me. That's going to create terrible imaging and tonality problems. You'll be able to localize them very easily. Plus you'd really need to make the modifications to the enclosure you mentioned and I doubt they wanted to have customers cutting holes. It seems like this product was setup to be as drop in friendly as possible.

That's not really an issue as far as I'm concerned here....The low / mid-bass and sub bass frequencies really don't have a significant impact on imaging as do the midrange and higher frequencies do...Also having both lower the mid-bass and subs separated out will produce higher system efficiency with less distortion rather than a system simply relying on one sub to doing all the heavy lifting from 20hz to 1000hz as the OEM Audio sub does...

But yes, there would be added cost to providing a narrow rear panel with ports already installed...They could have provided the customer with the OE narrow rear panel and 2 ports already installed costing them less than $75 dollars...

Like I said earlier, I think had they evaluated the system after doing the port mod (or just simply removing that narrow rear panel) they may have approached this a bit differently....

------------------------------

That said, I'm very eager to hear some feedback from those folks that do decide to install the OEM Audio+ system...Particularly from those that had already done the OE sub system mod for comparison....

Yes you make a valid point but a drop in 9ch Mobridge amp/dsp is $1000. For another $300 you can buy a 300w rms 8" enclosed sub.

My build for example, the labor for the amp/dsp is $700 with a planned tuning time of 4 hours. $50 to drop in an enclosed subwoofer of choice and another $150 in shop materials.

$2200 installed at a high end shop.

This results in an OPEN tunable platform with triple the power the OEM audio plus system has.

Sure they do but most people just don't care. They simply accept that the sub bass and mid bass is coming from beside them or behind them instead of in front of them. Then, the more they turn their system up the easier it is to localize.

Also having both lower the mid-bass and subs separated out will produce higher system efficiency with less distortion rather than a system simply relying on one sub to doing all the heavy lifting from 20hz to 1000hz as the OEM Audio sub does...

I agree with this and as well as the simple fact that you don't have any options in this car outside of custom fabrication because of where they placed them. It is what is and you just roll with it. Do we know that they completely by passed the stock woofers though? I don't recall seeing anything about them in the literature.

The only selling point of this system at the price point they're charging is the DSP corrections they've made. So realistically, if it's done correctly there should be a significant change. We're talking about fixing an enclosure for woofers vs custom EQ, TA and phase adjustment for a whole system. I could walk out and spend less then a hour with a car that cost $15k brand new, measure and make changes then run those changes through a convoluter into a MP3. I guarantee anyone here listening to before and after would say there is a massive difference. But I'm making some assumptions as to how much work they put into tuning the system that may not even be there.

Yes...the subs are completely bypassed as they mention on their website and in my phone discussions directly with them...

*Factory subs are disconnected. After extensive evaluation, our acoustic engineers ultimately determined that omitting the use of the factory subwoofers rendered the best results to the overall listening experience. Even with attempts to re-tune, filter, and/or treating the housing, we found the factory placement (even with upgraded drivers) to be more of a distraction than a contribution to an accurate sound stage, and a misappropriation of resources.

Yes, when I spoke with them on the phone they confirmed they are not utilizing the oem subs due the poor enclosure design.
