mga sir patulong naman ako pili ng amp...

used JL 300/4 class A/B amp (8000php)
JL Audio 300/4 (jl3004) 300 watts, 4-Channel Amplifier

bnew PPI P900.4 class D amp (10000php)
PASMAG | PERFORMANCE AUTO AND SOUND - Precision Power P900.4 Amplifier

bnew Soundstream TX4.560 class A/B amp (4000)
Soundstream TX4.560 (tx4560) 4-Channel Class A/B Tarantula Series

medyo more on PPI or soundstream ang gusto ko ngayon...
PPI dahil its so powerfull and class D.. i think.. its wiser to go class D now

soundstream naman dahil mura lang and may sub control pa.. kayalang why ang mura nito?
