Currently replacing the Bose system in my type X with an aftermarket unit. Trying to keep things simple, so I'm trying to use exisiting wiring where possible https://www.nopistons.com/forums/pub...IR#>/smile.gif



Rewired the original loom to ISO connectors, but worried about the main feed; on the Bose the head units don't have an amp, so the feed wire is pretty skinny (maybe 0.75mm?). However, the new head unit with its internal amp has fatter cabling. The old wiring is protected by a 10a fuse, as is my new head, so this implies to me that the wiring should be OK as the fuse should be lower rating than the wiring https://www.nopistons.com/forums/pub..._DIR#>/sad.gif Any comments? I was thinking about taking the feed from the existing amp relay (30a) but that's a bit of a pain, so I'd appreciate some advice.



Thanks

I'm slightly confused... are you trying to replace all the bose speakers and putting on aftermarket subs and headunit??



If its just headunit, you should be fine. If its an aftermarket amp then you need to run a larger wire..

What I'm doing is taking out all the original BOSE equipment, including amps and speakers. I've got a new head unit with a built in amp which I am going to use to drive 4 new speakers directly. At the moment, I'm not intending to use an additional amp / sub. My worry is that all of the amplification current is now coming down the wire which previously only did low level stuff on the BOSE head.



Thanks for your help https://www.nopistons.com/forums/pub...IR#>/smile.gif

It all depends on what head unit and what kind of speakers.. But for direct replacement speakers, I say stock wiring should be fine.. If you are upgrading to some high end (like Boston Pros), I say you might want to consider running thicker wires.



But to be honest, most head units don't push that much watts to worry about upgrading wires.. I'm using stock wires for my door speakers (Boston pros).

Cool, thanks for the feedback https://www.nopistons.com/forums/pub...IR#>/smile.gif
