Mga Tsikoteers..help me rebuild my trashed car audio system

Currently on my 92 Sentra:
Kenwood Cassette Player (eats my tapes, so i bump the radio haha)
Kenwood rear speakers (all blown out)
Front speakers (not sure what brand, but, still works)

My total budget is about 8-10K. I plan on getting a new pair of seperates, should I keep the working speakers? or get rid of them? they're not very "clear" for SQ..but they're ok nman. If i do keep them, should I put the new seps to the front or rear?

Would the setup that i'd like to have fit in my 8-10K budget?
I hope to have a setup with the following:
Headunit- CD CD-R/CD-RW MP3 with AUX input (Targa? Proline?)
New Pair of seps
Amp (Proline ok ba?)
Subwoofer

I'm leaning towards Sound Quality, but, i'd like my bass to "boom boom" (without heavy distortion) when I need it to. I mostly listen to R&B n hiphop, but, i also like alternative. I'm planning to go to Banawe next month, so If you could recommend any shops in Banawe, or products that you think might fit nicely in the budget and at the same time provide me with better listening, pleae feel free to put your inputs in. Thanks
