I have just bought the gear for a DIY audio build eeeek
- Alpine Halo 9 head unit with some 2mm card & carbon wrap to make the panel behind. This is the one with the big 'floating' tablet look that covers the entire gap left when removing the RNS-E
- Audison Prima 4D 4 channel class D amp, to be installed where the B&O amp currently sits, to drive the door 3 way components
- Rainbow SL-C6.3 PRO semi-active 3 way components for the doors - woofers driven by 2 amp channels & the mid & tweet share a crossover powered by another 2 channels of the amp
- B&O plug loom - expensive from the states - this is so I can tap into the car's speaker lines without having to cut / splice the car's loom so I can put it back to stock easily afterwards if needed
- 30 sheets of silent coat for the doors
- Autoleads Control PRO 2 Steering Wheel interface CP2 VAG52 - so I can retain steering controls
All in has cost £1300 or about $1700. NOrmally I would sell off the B&O stuff, amp, and the RNS-E to fund this, I have done this in my other cars but gut feel is the Audi needs to have its original kit with it for resale
That's it for now - the beauty of this install is that I can use the B&O amp's power cable, and I will also use the existing wires that take the audio to the B&O amp for the signal - so I will not need to remove the whole frunk & associated plastic panels, as I i'll not need to connect additional feeds to the battery. The existing circuit and fuse for the B&O amp are rated sufficient for the new amp so that will save me hours of fishing power cables through the front bulkhead. Also I will not need to remove the center console which looks a hassle, to get any cables to the rear bench as I am using the existing connections
If there is not enough bass I will then add a home made box for the rear shelf with 2x Hertz 8" subs, then I will need to take the above steps to add an amp.
So all in all, it is a low effort way of substantially improving the sound and functionality in the car as doesn't involve too much stripping down. Will report back!
