Dose any one know where I can tap in to the Sub's feed?
Do you reckon this can mostly be done from behind the radio?
If you look at the Alpine Retrofit fitting guide (other sticky) you will see that the feeds to the front speakers (subs and mids) run as a single pair (Front L and Front R) to the front door sills, where they are spliced and split to feed the Sub and Mid separately. So, you will need to run new cables directly to the subs/mids/tweeters or tap into the existing speaker feeds in the sills.
