I just wonder, is it a real DPS is in canton amp? Or is it just a digital amplifier connected to the head unit which is the true DSP? That might be true since the equalizer is the same in MIB3 even without Canton. I do remember that in my Octavia III I was able to switch the head-unit to canon even when I did not have one. Only deference was lack of sound but all other options was left untouched.

That might be a game changer for all canton users. I will try to contact with the developer, but those mods are good only for the head-unit, not for canton/dyna audio

100W for 8Ω is 3.5A but 100W for 4Ω is 5A so there only 42% more current for the same power. Max power for 4Ω for FDA802 is 150W and 6,12A so without to much volume for the sub it should work just fine. Thanks for the image. That explains a lot. Will see how the sub will perform in the car. That is why I have 2x4Ω coil in the sub. At first I was planning to buy 10TW3-D8 but that is an expensive sub and not good for such small fit-box. Would be a waste of mony. 10TW3-D8 Qtc- 1.065 , MP 250 D4.3 PRO Qtc- 0.876.

Those part are interchangeable. Since there is an option in the coding so it is ready for this function. It is possible that there is another module just for the microphones. This one would make all the calculations and measurements. Head unit would be just to play it in the speakers. I do not have any schematic for Audi and I would not bother to look for one, but it might, just might, be possible. That is why I use both channels for one sub. 200W will be plenny. If there would be 200W at all. I did some tests with my Fit-Box stuffed with nice, acoustic foam. At 135W/coil there was out of linear excursion in just 15L enclosure. This not that powerful sub in a real life, and definitely not that heavy. It also have very nice 50-70hz flat response. Not louder than 30-50Hz. Nice, uniform, flat bass. No rumble. That is unfortunately in the the nicely dumped room. I did not put it in the car yet. How do you know that there is a high pass filter? I will eventually test the signals from all channels. Will see how those crossovers are set. I still believe that there is enough good in that factory Canton system.

This audio equipment has been used also in other Vag cars, like Audi, so I can imagine that in those cars there is a nice cancelling system active on the same audio hardware. Theoretically, it might be possible to implement the same system in Superb but that would be a really custom job. You are right about level compensation. In case MP 165.3 PRO SPL is 93dB so quite high for that power. We can assume that SPL of the factory OEM will be the same. The only question is how Canton amp will behave at 4Ω. Half the impedance will double the power so abut 3dB louder. I will test that in reality soon enough with the sub.

Like I said last time bass will be added only below 50hz so everything above will be the fronts. Mind the fakt that I'm mounting a 600W Sub with low SPL and will be driven by 200W amp so in reality will be in pair with the fronts in terms of the volume. It is nice that Canton amp have one output per speaker. That get rid of a lot of distortions. If this amp will work with the sub I will also change the fronts to get rid of this lack of control, plastic speakers. Honestly, I prefer full range powerfully fronts over a sub-woofer, but since I already have an amp for one I'm going to use it as it should be used.

Can't argue with that. But there is always a room for improvement. I must say that DSP in Canton doing its job quite ok. When I turn on Dolby ProLocic but not set to surround but point only in the front, stereo opens up and make very nice scene. I know that is a DSP sound but must admin that it is the best surround sound I have tested. The reason I'm going to change the SUB is that this one is very badly tuned. It is in pair with the front which makes the bass louder but just a little richer. This is not the point of having a sub. It should extend the front frequency response below 50hz and not overlapped it with higher bass. Overall my setup will not be louder but definitely more defined and rich.

I must say that it is a tough choice. First off all the standard OEM main unit is weak one. Any upgrade on that would not be very good. However if you have access to Focal VW IS 165 for a very low price I would consider this option. Match 5.4 is just more advanced amplifier and in the same time not very powerful. 4x60W@4Ω + 90W@4Ω for a sub is just not good for the price. Other options: Do not waste time and mony for a rear set of speakers. They are good only for making noise, messing with the phase shifting in the car. For a music listening you should focus on the fronts and sub. Good front will give you the great kick and sub will add ultra low earthquake. For the front I use Hertz Audio speakers most of the time. There was a an old series EV165L with only 100W RMS but what a speaker. Frequency bandwidth 50Hz and that could be felt. Deep and very strong, punchy bass. Now only MP 165.3 PRO are good enough. For a sub-woofer look for a fit-box. The best option for any setup. And beyond all a good amplifier is mandatory. I would use JBL MS-A1004 for front and sub. That is 4x100W@4Ω or 2x100W@4Ω+1x200W@4Ω. If you are not planing to use 100W/ch amplifier don't bother with any sub or front speaker change (Maybe Focal VW IS 165 for a very low price) wast of time and money.

For an OEM system is ok. Not the best I'v heard but ok. However there is much to improve. Front front door woofers sound flat. Weak punch. A a lot of power but poor quality speakers. I'll deal with them later. Maybe MP 165.3 PRO. Sub-woofer is a joke. Tuned very high and complete lack of everything below 40Hz. Overlaps frequency with the front door woofers. SLOW and BOOMY. New will be MP 250 D4.3 PRO with custom made closed FIT-BOX and massive low-pass filters. With both speakers I have the same problem. Only 4Ω available. Will see how good those amp IC's are.

New topic about this amp:

Hello everyone, I decided to create a topic about canton amplifier 3G035466. There is similar topic on Octavia forum but there is a 3Q0035466A amp. Speaking of speaker ratings for the Canton system in the Superb...... Some photos attached. So, there is 3x TDA7803A nad 2x FDA802. TDA7803A is a quad channel amplifier capable of deliver – 4 x 27 W 4 Ω @ 14.4 V, 1 kHz, THD = 10% – 4 x 47 W 2 Ω @ 14.4 V, 1 kHz, THD = 10% FDA802 is a dual channel class-D amplifier capable of deliver– 2 x 120 W /4 Ω @ 35 V, 1 kHz THD = 1% (2 x150 W /4 Ω @ 35 V, 1 kHz THD =10%) – 2 x 140 W /8 Ω @ 50 V, 1 kHz THD = 1% (2 x180 W /8 Ω @ 50 V, 1 kHz THD =10%) Link for datasheets: https://www.st.com/resource/en/datasheet/tda7803a.pdf https://www.st.com/resource/en/data_brief/fda802.pdf FDA802 is capable of driving 4 Ω speakers but on 35V. I cannot find any full datasheet so no characteristics is available. But judging by the main capacitors voltage (63V) probably it is powered from 50V so 4 Ω speakers might be an issue. I will test that soon. So info from a Skoda brochure should be quite precise. 610W is and RMS power.

Hello everyone, I have a a problem. I was preparing myself for a new Superb 3 liftback and already started to collecting Audi gear to change factory sub. The plan was to replace just a sub and power it from Canton AMP. The only sub 2x8Ohm was JL Audio https://www.jlaudio.com/products/10tw3-d8-car-audio-tw3-subwoofers-92193 But since the Fit-Box is only 15L and this sub is not haveint the best responce I bought HERTZ MP 250 D4.3 PRO https://hertz-audio.com/product/car-audio-subwoofers-mille-pro-mp250_d4_3/ This one is 2x4Ohm. It should work just fine, but those info was about 81A035223 which I should get in my Superb. Insted, I got 3G0035466 So, what IC this one have? I it going to work on my HERTZ?

Display stays the same. Central unit is hidden in the glove box one the left. Where you put an SD card.

It doesn't matter. Those are the same modules and the price is the same. The only difference will be the car picture in Car Data menu. There are non oryginalna radios available but the proce will be the same even higher.
