Hi guys.
Looking for info on the 2021 Polo Vivo radio model 340G. Car only comes with 2 speakers in front doors with tweeters. I would like to install on rear doors. Looking for 340G output specs and door speaker size. Thanks.

I recall fitting 6” splits and 6” co-axials in my polo.

Managed to fit a set of 6" co-axials in the rear doors only to find out that the output on the 340G radio is limited to 2 channels only even though there are 4 channels output. Apparently you have to use the VAGCOM software to change the settings on the VW radio... Any one else have this issue?

Yes i would also like to fit rear speakers and maybe a small 8" sub as well.
