Went to Megamall to check Targa and they also offered me Crystal Audio. I saw lots of thread saying Targa is bang for the buck. Here goes:

Crystal

CXE (200W) - Php 6,000
Bizark Amp (800W) Php 18,000
Amp Kit Gauge 4 - Php 1,600
CMP x 12 (Subs) - Php 15,000
Holder blah blah - Php 600
TOTAL - 41,200

Targa

Targa Sub 12" - Php 2,600
F4100 AMp - Php 9,100 (SALE: Php 6,500)
MX 259 (5", 120W, 2-way) - Php 900
X 653 (6.5", 150W, 3-way) P1,200

Anu masasabi nyo?

Eto sabi sakin:

No need to amp the rear, surround naman yun (same concept home theater). I find it logical, even my surround isnt that powerful...
Rear speakers can be directed to HU
For the Crystal setup, Fenton will do but Bazark is better
May single/dual coil pa silang mentioned, 4 and 8 ohms

I'll edit this post if i remember other stuff he mentioned.
