Speakers for a LX 1.9 5dr?

[sHAYM4N]

Hi guys, new here, just wondering if you could help on what speakers I need for my pug LX 1.9 5dr? Really new to all this, but rear os speaker has blown, my headunit gone crazy (its had a hard time).

Just getting my new head unit today a Kenwood KDC-BT31U Kenwood Electronics UK Ltd. | CD Receivers > KDC-BT31U so wanting to do the speakers as well

Assuming that I'll need 13" for both front and back (seeing as how the 5dr speakers are door mounted), but they're component aren't they? So wouldn't need a tweeter for the front if I use the installed one, what about the back?

Any recomendations? Don't want a thumping machine, just something that sounds nice pretty loud and clear.

Thanks in advance
