OK with MS-8...sure I imagine it will be ok....though its VERY powerful and you will likely have to turn it way down...
ID10, JL10wX, Morel are popular subs for this car, usually in a VP enclosure though.
You have plenty of power for the sub, just find a sub you like
As for the speakers if you want as efficient/loud as possible, you probably want the DLS R4 with a DLS 424 for a center. They are both rated 94dB/1w/1m@4ohm (97dB 2.83v/m)
You will still be limited by the sensitivity of the OEM under seats which I don't know what that is.
The SSMB8 are 89dB 1w/1m@4ohm as an example (92dB/2.83v/1m). I don't know about OEM.
SWS are 86.7dB (presumably 1w/1m at their respective impedance would place them at
However Technic has said the SSMB8 are MORE sensitive than SWS...so YMMV
FS:Sub Amp - works w/ Technic harness! MRD-M300 - cheap
