pare, if you don't cranking up your car, this is what i suggest.

1) decent pair of 2 or 3 ways separates: max 8,000

2) 4 channel amp with built in crossovers. minimum of 4 x 50 watts with bridgeable rear channels.: max 12,000

3) decent 10 or 12 inch sub: max 5,000

total cost will be 25,000 plus 5,000 install and wires. okay ka na.

ito rin ang plano ko. i have had big ssems before: over 1800 watts rms, pero nagsawa na rin ako. balik lang ako small but clear system.
