I'll probably end up with connecting it to the fuse as it should be. I've ordered a new dash, so that's gonna be changed anyway, so hopefully I will get access when changing those. Plan B is tap-a-fuse connection thing, but I couldn't find any with 2,5mm2 lead on, so I'm not to keen on that.
I had the seats out the a few days ago, and it seems easy enough. I just have to cut the splice and solder on wires for the sub and door speakers. Pretty much the same as mounting the Alpine retrofit kit. The coding part is easy enough as well, I'm quite familiar with the programs after retrofitting a lot of other things. ![]() Thanks again for your help, there isn't that many people that have done this, as everyone says it's "impossible". |

I’m waiting on a logic 7 kit coming and from everything I’ve seen this has got to be the most straightforward way of going from base audio to logic 7. Just need to find the right pinpoints for the head unit as I’m getting slightly different results when searching. |

If you have an LCI then you can just plug the l7 loom into the speaker/sub plug under the kick panel on each side, this plug is used for splitting the radio output door the door speakers and the subs.
If you are pre-lci then its a crimp connector so you would need to split and recrimp. Whe I did mine, i ran new wires from the amp and by-passed the OEM loom (so that i could go back at anytime).

I haven’t got a clue which wires I need to tap into either so might just get the local audio installer to do it. Still waiting on a replacement amp which is really annoying. |

the connector is under the kick plate next to the seat roughly where the seat controls are

I might have another look on the weekend as I was just loosening the seat and trying to pull the carpet up a bit. I’m waiting on the subwoofer enclosures coming so will probably wait until they’ve arrived before doing it. That way if I find that connector, great otherwise I’ll let the installer wire it up but save a few quid by just having them do the wiring rather than have to take seats out, trim off etc.

Success. Got all the speakers in except the parcel shelf which I’ll do one night next week.
First impressions from a 2 minute listen are… that it’s well worth it if your got crap base audio. For what I have paid it’s a massive improvement. |
