# Installation School 5 category lessons, built on `` . Real, hands-on wiring/hardware detail exists for FP-8A, FP-12A (DSP) and FX-4 (Amplifier) only. ## Lesson 1: DSP Installation (FP-8A / FP-12A — real) Hardware Interface + Packing List content is real and . Key installation facts: - High-level speaker output note: some vehicles' speaker-level output carries no DC signal — requires ACC mode instead of HOST mode for correct DSP power-up in that case. - Input impedance to respect when wiring: FP-8A Low Level 15KΩ / High Level 22Ω; FP-12A Low Level 15KΩ / High Level 390Ω. - Full text: ``. Other 9 DSP SKUs: dimensions/weight/mounting only (``); no wiring procedure documented. ## Lesson 2: Amplifier Installation (FX-4 — real) Real ground/power/REM/speaker wiring procedure: - Power: +12V terminal to battery positive, fuse placed ≤30cm from the battery. - Wire gauge: general minimum "#10 gauge or thicker" (Wiring Instructions page) vs a distance-based table on the Operation page (3m → min. 8 AWG, 6m → min. 6 AWG) — **two different figures in the same manual, presented as-is, not reconciled** (see `` Module: Installation). - Ground: negative ground, 12V DC operation only. - Speaker load: 2Ω/4Ω stereo, 4-8Ω bridged. Other 12 Amplifier SKUs: dimensions/weight only; no wiring procedure documented. ## Lesson 3: Speaker Installation PENDING VERIFICATION — no local manual or installation document exists for any of the 15 Speaker SKUs. Only Master Data dimension/mounting fields available. ## Lesson 4: Subwoofer Installation PENDING VERIFICATION — same limitation as Speaker; no local document for any of the 10 Subwoofer SKUs. ## Lesson 5: Accessories Installation PENDING VERIFICATION — no local document for any of the 3 Accessories SKUs (FRC-02, FRC-03, OTG-LINE). Real `compatible_product_ids` values exist (which DSP products they connect to) but reference 3 unresolved product codes — see ``. ## Installation checklist (real items only) - [ ] Confirm fuse placed ≤30cm from battery (FX-4; verify per-SKU for others — PENDING) - [ ] Confirm negative ground, 12V DC (FX-4) - [ ] Verify wire gauge against BOTH FX-4 manual figures (8 AWG @3m or 6 AWG @6m; #10 gauge general minimum) and use the more conservative (thicker) one when in doubt - [ ] Keep power/speaker cables physically separated from signal cables (FX-4 Interference guidance) - [ ] For Mercedes-Benz W206 platform vehicles: confirm customer understands the MBUX head unit cannot be replaced — set expectations before quoting installation - [ ] Speaker/Subwoofer/Accessories: no checklist item available — PENDING VERIFICATION ## Inspection sign-off PENDING VERIFICATION — no formal post-install inspection/QA form exists anywhere in this project (Cursor's domain — Admin/Dealer/QA — may already own or plan to own this; not duplicated here without verification of that ownership).
