Hello everyone,
I've decided to start a build log to detail my adventures with installing an upgraded audio system. I have a 2021 Model 3 SR+ that I picked up in December 2020. After realizing that the stock system is pretty poor, I'd did the bare minimum upgrade of using a TeslaOffer harness to enable the missing front speakers. I also attempted to use a powered RockFord Fosgate P300 10" sub, but didn't at all like the results.
After spending some time talking to a local higher end audio shop, lots of time in the forums, I've decided that what I needed to do was invest in a DSP, a quality sub, and some quality front components. The goal will be to have a 3-way audio system up front. So that means I'll just run the front doors, sail tweets, and left/right dash mids. I will disable the center mid/tweeter and the "imaging" speakers in the A-pillars. I'll also use the factory rear door speakers for rear fill. Since I don't have any rear deck speakers in my car, I'll leave that alone. All of the speakers except the subwoofer will be driven by a Helix V Eight MK2 DSP. A sub will have seperate amplification. My other goal is to keep this as simple as possible with as little equipment needed to do it.
As of January 28th, this is what I have in hand and on order:
Teslaoffer harness - ($79) Will modify to send all the audio to and from the amp/dsp.
Helix V Eight MK2 DSP - ($1300) This gives you 8 75W amplified channels, and 10 processed channels
D'Amore E350.2 Amp - ($179) 350W x 1 bridged at 4ohm
Hybrid Audio Clarus C10SW D2 - ($200 used) 10" subwoofer
Audiofrog GS60 - ($280) 6.5" speakers for front doors
Audiofrog GS25 - ($230) 2.5" wideband mids for L/R dash
Audiofrog GS10 - ($230) 1" tweeters for sail panels
Knonoise Kollosus Edition Sound Deadener - ($150) 35 sq. foot of CLD material for trunk and doors
Absolute C10BK carpet - ($25) Black carpet for the sub box and amp rack.
4ga wire, 8ga wire, 16ga wire, fuses, dist blocks, etc.
Left to order:
Some form of closed cell foam to put over the CLD in the doors (probably will use Resonix).
Current Progress:
I've decided that the subwoofer will live in the "sub trunk", and the amps will all be mounted on a board that will mount on the trunk deck. I've already ordered up some "plus nuts" and inserted them in the factory holes in the trunk deck. Now I'll be able use use some 5/16 bolts to mount up a board. Next step is to cut up a piece of 1/2" plywood.
Built a prototype box for testing out of 3/4" MDF for the subwoofer. Most likely I'll keep it and just put a nice trim panel over the top. It's .83 cu feet sealed as recommended by HAT.
