okay so im a noooobb at BMW audio, Ive done other cars but this is totally different thing. So i plan on upgrading my audio, and this is what i plan on buying. Could somebody draw in where i should wire to get the best sounding audio out of this, because honestly i would have no idea were to start.....
so i started it off for you

the speakers are KICKER KS502 5.25 AUDIO COMPONENT SPEAKER SYSTEM

the sub is a 10" kicker L5, and the amp, a 900w mono block amp

..thanks again (any advice on what else i should get or shouldn't get would be appreciated too)

and its a convertible if that matters

Are you wanting to run the Components as well as the other factory speakers in the car with stock amp?

Would it sound better on the amp or off the HU?

Well it all depends. I do know that the amp runs off different frequencies so you will probably just be better off just bypassing the stock amp and run your components and your rear speakers off of your HU. That is what I did with my 328IS. Then as far as wiring everything what specifically do you need help with?

hmmhhh somebody told me i wasnt allowed to run everything off the HU because i have 10 speakers or something along the lines of that.

STOP STEALING OUR PICTURES!! :)

If you want to use the components you indicated you cannot run them off of the factory amp.

haha yeah sorry, but can i run all my stock speakers off my HU and ditch the stock amp

okay nevermind i think i got it, i took a look at the back of my stock radio and i think i know what to do now.

Are you using
the speakers are KICKER KS502 5.25 AUDIO COMPONENT
or not?

These are not stock. If you are just wasting time and going to throw contradicting statements out, please find something better to do with your time.

i doubt it.

there is endless information here covering what you are asking. for starters, peruse the parked threads at the top of the forum. then when you have more specific questions, use the search function specific to this forum.

no, you cannot connect aftermarket component speakers to your otherwise stock system. no, you cannot drive aftermarket speakers from the stock head unit. no, you shouldn't drive aftermarket component speakers from an aftermarket head unit. no, you cannot power the stock speakers from an aftermarket head unit.

yes, you can drive the oem amplifier and speakers from an aftermarket head unit (but why?). yes, you can add a subwoofer to the otherwise stock system (but why?). yes, you can connect an aftermarket amp and component speakers to the stock head unit. yes, you can (and should) replace the entire system.
