OK i think this is how i can make it work???? "picture included"

i have an 04 mazda 3 hatch with the regular stereo 6 disc changer. no bose. i want to keep the stock HU but go with after market amps and speakers every where. i have came up with this rough schematic to show you people and i wonder if it will work. your comments are appritiated

huh? surprise no one ever answered this for you.

When you keep the stock HU it lacks the RCA pre-outs aftermarket radios have. SO, you need to get "hi/lo level converters" that or sometimes certain amplifiers that this level converter built in, that will give you the RCA pre-outs.

Yeah you could do this, i would suggest you either get a 4 channel amp and just use two loc's one for speakers and one for sub. You will keep some sound quality that way. having three sep amps probably isnt the best thing for your can unless they are under 600 watts rms.
