Hey guys finally got my Amp Alpine MRFP250 now my question is i am going to be using the high level outputs what size wire should i use for this to send these high levels to the amp will speaker wire be good and what size wire should i use from the amp back to the speaker leads behind the dash as i am using the factory speaker leads to the speakers as it will be a pain to re-run

 

in that case just use the same ga. the car already has... which is probably around 16 or so... other wise you just choke the bigger wire when it turns into the smaller wire...

 

16 awg is fine.
