any 1?

depends.
I've done in on my girlfriend's car (mk3 Punto), that only has 2 outputs - one for each front speaker. Basically i spliced into the outputs, splitting each cable into 2, then the pair you just created connect into the amp's input. I only connected 1 side for the time being and never connected the other, now she's happy with it and doesnt want anything changed lmao cos normally when i touch something again, it breaks lmao...
it does have a downside, you're halving the volume to the front speakers, but hey how loud will you ever want them to go eh

+oh, and i forgot, the way to tell which cables go to the speakers is: get the speakers out in the door, and look at the colour of sleeving. it should then be the same at the stereo end.

+on another head unit i did, it has rear RCA outs, so just used the rear channel for the sub. This is awesome, because if you want to increase the bass going to the sub without increasing bass going to the speakers, you just 'fade' it to the back

simple response is yes.

however, imo you would benefit more by altering your approach slightly.

instead of buying say a sub & amp package, opt for a sub & a 4ch amp.

use a speaker ISO to RCA converter on the headunits output connectors, run the rca's through the car into your boot,(if you only use one set of rca's, then use a rca splitter to feed both fronts and rears on the 4ch amp).

drive your front speakers with the front ch's of the amp.
drive your sub using the rear ch's of the amp bridged.

this way will work out more expensive, but you will get far better results.
