There are three systems world wide that are common one that isn't

stereo = no amp 6 speaker no tweeters also called base system world wide.(Only in the US 2010 and early 2011 )
Hi Fi 8 or 10 speakers depending on the year also called Premium but not the best one.
L7 also called Hk or Top Hi Fi Surround sound with 13 or 11 speakers depending on the year and a 9 channel amp
There is another version of this not common with even more speakers called the personal stereo .
Sirus radio is not a determining factor.

Identifying your system should be your first priority as solutions are different for each one.
You will need another amp if all you want is subs.
Also describing what you want in a system would be good as too many people think subs
are the solution for everything.
