i got a problem.....i have 1200W kenwood 4 chanel amp......and 6inch behind speaker.....and 4 inch front speaker....and using alpine head unit.....do i need to buy another amp to support my sub woofer or buy a amp built in with sub woofer....please help me....thank...

The 1200w should be max power and won't be powerful enough to power a sub. Provided that your HU has 3 pre-outs or you have pre-amp or electronic crossover, then add another amp for your sub. This is the most simply way to add a sub.

how much a mono amp,crossover and woofer normally including installation..thanks....

mono amp c u take wat brand loh....mine magnat around rm7++

It is better that you tell ur budget so people can suggest you what brand to get..

around 1k?????i am not so sure whether to get crossover....

another thing my tweeter got a lot of noise.....and the alrm sensor is near with it..is that possible alarm casuing this...

I don't think alarm sensor will cause ur tweeter nosie..
But what type of noise from your tweeter?

it is like hiss noise.....only from the alrm sensor side tweeter got noise...other one no noise at all...wat is the cause?

Wiring maybe got problem?
Anyway with rm1k you cannot do much, the most is a 2 ch amp, a 12" sub(rm400 each) then a passive crossover which is a coil that cost you rm80-rm150. This coil is use for reducing noise going into sub thus you have more solid bass, as the 2 ch amp sometimes its low pass filter cannot filter out all the voice. You can try with and without the coil. With coil the woofer's movement is less compare without coil that moves very fast. If get e-crossover will sure burst your budget of rm1k.
