no need rear speaker, just change front speaker, get 4ch amp and sub. 2k should be enuff, can get much better brands than caliber

nope, pls check thread discussing good/bad brands

somewhere near speaker, but careful not near car's ECU, or near the amp's power cables

supposedly the ideal place to put it is as close to the speaker as possible, but in car it makes it hard, if u put inside the door, it might get wet

in door trim is good... aiya car audio shop pull wire thru the door rubber grommet everyday one la, see how they do it and try yourself....

3k can get focal component, 4ch amp and sub

guess type G is a good place to start...

get alpine, not alphine

get front components, dont bother with the rears

yea can get boston or alpine

can, but if can find something bit more powerful would be better

can, but it will be running at 2ohm, so amp will be hotter, and signal to noise ratio 10x worse... so, not recommended lah

i think all also under 1k, but decent or not....not for me lah

if your choice is only alpine and dls amp, id probly go with dls
