Ramee's Tiguan Build Thread 155KW DSG

Start of the second phase of audio upgrade.. Hardest part was to decide the best place for sub.

Sub will go here !

Got a 10 inch MBquart sub which can play as low as 25 Hz

Next tried to find a place to build a custom fibreglass box with not much luck. Decided to build one myself. it is def. not easy work IMHO still work in progress ...

Got a digital sound processor (Audison Bit One) which is capable of doing wonders to the sound quality ..

was thinking of upgrading my speakers. this looks like trouble haha i guess i'll get a professional to do it. the sub location is unexpected! wonder how it will sound on the side panel.

Hey Ramee,

How come your inputs are RCA's? Isn't the line level input on the MRXV70 a special plug, or will it take RCA's for the line level as well?

I am sure MRXV70 special plug is for speaker level inputs. RCA connectors of the AMP needs a line level signal (pre amp). So I enabled line level(pre amp) signals from RCD510 using a VAGCOM cable.

Funny thing is even though MRX amp's manual mention signal sensing power on work only with speaker level inputs, It will still power up with pre amp outs from RCD 510 feed through RCA connectors. This will save you from trouble of wiring separate remote wake up line for the Amp.

Hmm. Does anyone know if you can do the same (enable line level) for the RNS510?

I think for the RCD it's "VW Sound System" and disable "Monitoring" but I don't have my VCDS on me to check atm.

Hey Wynnston, Yes It will work for RNS510 ... Actually I followed the RNS510 coding for my RCD 510 and it worked !! Original instructions are for RNS510..

After looking for many weeks for a ready made down pipe ( 3 inch), I decided to custom build one from a local shop. It was not a easy job as it looks IMO and had to do few iterations to get it done. Now It is at a functional level but need some work to make it look nice

3 inch down pope with 200 cell cat makes car much more enjoyable to drive. I can clearly feel the increase torque at low rpms due to earlier turbo spool. Our DSG tigs always try to keep engine RPM low like 1500 or below so turbo spool around 1700 is always a good thing when need a quick acceleration.

With the new down pipe car sounds mostly OEM and I like to keep it that way because want to preserve Tig's sleeper characteristics
