Hi, can someone give me advice. The factory radio on the Vivo, does it have RCA output if u want to install a Amp/Monoblock?. If not, can u change it so that there is a RCA output, or is the best to replace the head unit.. Also someone out there that tried to fit a slim woofer under the front seats, was thinking of trying that, very small space. Maybe a 8" or 10" slim woofer(know u get the active woofers also).

Which head unit is it?
It will most likely have just amplified speaker level outputs.
Find a sub that takes speaker level inputs and that will turn on based on audio signal. I'm sure most compact under-seat subs will have a high level input so you can do away with needing a remote turn-on wire.
I looked for line-out converters, but I recall these headunits do not have a remote turn-on wire and there's nothing that can determine that off the CAN bus.

I installed a Pioneer TS-WX70DA in the boot this way. Bought a connector harness from the local car audio shop, spliced the speaker wires to run to the sub and wired the power to the fuse box under the dashboard. It's just a 100W sub so no need for massive power cables running through firewall.

This was useful when I was looking:

Actually pull the headunit and see what model it is. That google search brings up all sorts of stuff.

It's one like this

Doubt that is going to have any pre-outs/RCA.

Why not ditch it and get an aftermarket single-DIN headunit that has pre-outs/RCA? I know it's another expense, but later down the line you will be ready to add an amp.

This kinda looks nice:

But there are others for less.

Best thing I did in my citi was swap out the stock headunit for a Kenwood and then did front speakers.
Worth it just for being able to tweak the audio settings.

Dont think there is any RCA on the back of that HU. Its a pretty basic radio, limited expansion options IIRC.

How do i remove this HU. Cannot get it to clip and pull out??

Buy a set of radio removal tools.
Or ask your local car audio shop to pop it out for you.
Or cut up a old credit card and make some keys:

You get a high to low level converter with built in signal sensing that will turn the amp on or off. Bought one when we put a sub and amp in my son's 2010 fiesta. Ordered it from Rivonia car sound and the model number was CTL200.

Today must be Line-Out converter day.
First on reddit, then on a polo forum, and now on VW club.

Was introduced to the Kicker keyLOC today. Very nice LOC by the looks of it. Contains a DSP too for tuning out some factory EQ issues. R2.5K though.
