This is usually a 10-Channel amplifier located below the front passenger seat. The Stock HU connects to this amplifier and CANBUS controls the whole thing. The output from the stock HU is at Line level when the stock amp is connected. The amp also controls the volume, bass, treble and mid-range. it is also a DSP. Quote:

I would not suggest any such modifications especially because it voids your warranty as there aren't any "stock" methods of doing this. You can however tap the signals from the stock door sub or woofer and use it as a source to the subwoofer amplifier. However, do note this additional amplifier can cause issues if this is not a CANBUS enabled amplifier. Please note in premium cars EVERY device has to be controlled by CANBUS. Quote:

Yes, there are eight speakers, however, these are independent woofer & tweeter channels. The stock amp is designed to output woofer & tweeter separately unlike in a conventional amplifier where a full-range signal is split using passive cross-overs. Quote:

The stock speakers are pretty good for the stock setup. If you're getting boomy bass, its probably because of the incorrect settings. Using VCDS software, one can get into the amplifier and choose the correct vehicle environment. Quote:

I still have a little over 1 year extended warranty and knowing SKODA i dont want anything endangering this.
2. I need the amp and sub to be totally concealed. Further i cannot compromise on boot space. My wife did not like what i did to the i10 with the sub enclosure and amp in the boot. For this i was thinking that the amp can go below the Left Passenger seat (but then my concern of the non standard wiring rears its ugly head). Regarding the Sub i am open to ideas. But one option i was thinking of was to use the two cubby holes on both sides of the boot. But i think this will limit the size of my sub, but can i compensate for the loss of size by putting 2 subs, one on each side?
3. Need advice on how to do the setup - where should the amp input come from, the HU, the stock amp/dsp and if so how do we consolidate the singals so that the amp can then resdistribute them. I have heard and read about Line Converters, DSP, Amps with speaker level inputs. But that only adds to the confusion.
Over to you folks. Thanks in advance for all your advice. |
Given your requirements, let me tell you the costs are going to be high. You would have to get a CANBUS enabled HU such as the Blaupunkt or Pioneer (not available in India though). The price can be between INR 40k-150K. This unit would give you preouts/subouts and the normal parking and climate control displays.
You will also have to get a CANBUS based amplifier, again available through Blaupunkt (only online), or obtain CANBUS adaptors for the standard amps, which may be tricky to adapt.
We can of course circumvent these at the expense of warranty by drawing line-outs from the stock HU, from the power IC input pins which then connects to the amplifiers (either subwoofer or full-range). In this case CANBUS wont be able to regulate the amplifier power which can have some bad consequences.
I have given you the options for you to weigh. Alternatively, you can talk to Sukesh of Vagtune who has recently done a similar implementation. This is infact a full blown Dolby-digital 5.1 setup. |
