What do i need?

Well, buti nandito si red_one taking care of the car audio section of Tsikot while I was gone :D

Anyway, here's my inputs for your 15k.
1. Get a secondhand 9887 - 10k
2. Get a subwoofer, box, and cheap amplifier for it - the rest (you'd probably need to add in a bit more)
3. Find somebody to tune your 9887

A 2DIN won't cut it unless you're eyeing to pay out more than 30k. The reason why I keep telling people to change their head unit first is because habol mo dyan are the DSP features namely time alignment and X-bands of EQ. Your main enemy in car audio is simply the car acoustics itself. Strictly speaking, sound quality is three aspects: soundstaging, imagining, and tonality. With a so-so head unit, you may achieve good tonality but fail the other two.

The adage of "change your head unit" is long past. This is because before car companies neglect the audio aspect of the vehicle this is what caused aftermarket decks to flourish. However now that the head unit is becoming more and more integrated with the car itself, car manufacturers are actually paying close attention in designing it so the gap from stock to an aftermarket deck is becoming closer. The difference between a DSP-capable aftermarket head unit and a stock head unit with a processor? Not much. Except for lower noise floors, THD%, and some variability between the frequency range measurements.

As proof, I'm running a stock head unit. For people who doubt my "audiophile" roots, let's just say not everybody has a 64k and 40k headphone at his home so I take my audio seriously.

But since most people won't readily believe me, go for the more usual route of:

1. Get a subwoofer and an amplifier for it. This fills up the lower-bass regions and would frankly be the most apparent upgrade for most people.
2. Go change your amplifier.
3. Get better speakers.
4. Deaden.
5. Finally change your head unit.
(no particular order)

And if habol mo lang talaga is clarity, keep it simple: sell your Targa and V12. Get a 5k separate component set and a 5k amplifier then be done with it.
