Got myself the new sr premium and love it. Sound wise stock is ok but I'm coming from the premium sound system in the CJ lancer (rockford fosgate) which was powerful but not that well defined.

Anyways what are the speaker sizes in the i30? are they 6 inch?
Is it possible to get an underseat amp with a sub?

Welcome.  I thought they were 6.5 "  but there is a fairly recent thread on here where a member has had his speakers upgraded and he is in the process off adding a subwoofer. I'll try and find the thread and post a link for you.

Best to read both these threads in full..

Subwoofer for PD i30 Audio and location of Tweeters

Thanks will check them out.
Does anyone want to share their equalizer settings for the stock speakers?

Also what is the 6 speaker setup in our PD i30s? is it 2 tweeters at the front near the windscreen, 2 speakers at the front doors and 2 in the rear?

Yep, that's it. I just have my bass elevated a notch. The rest set to default.
