Alpine iLX‑W670
No budget ceiling
The audiophile's working chassis — 13-band EQ, 6-channel time correction, and an ultra-shallow PowerStack body that mounts Alpine amps directly behind the radio, all for ~$350.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
It's wired-only CarPlay and Android Auto. No wireless projection at all — you plug your phone in every drive. Alpine spent the budget on clean DSP and a shallow chassis instead of a Wi-Fi module. If you want to drop your phone in a pocket and go, this is the wrong pick.
Dealbreaker? Runner-up Kenwood DMX9720XDS keeps SQ-grade 5V preouts and adds wireless CarPlay ↓
■ Every product has a catch. Verdicts that hide it are how bad buys happen.
Don't buy this if…
- factory amplifier, JBL/Bose/Premium audio, or fully integrated head unit (Toyota Entune, Ford SYNC 3/4, Stellantis Uconnect 4/5) where dash removal would lose features
- vehicle only accepts a single-DIN chassis (older GM, classic cars, motorcycles) — no double-DIN opening exists
- you want Android-tablet-style head unit with installable apps, not iOS-based CarPlay or Google's Android Auto projection mode
- goal is to keep factory radio and add an audio processor (DSP) and amps only
Wrong product for you is still a bad buy. These are the cases where we'd send you somewhere else.

Traps — this verdict avoids
Why the Alpine iLX-W670 is right for you
It avoids every trap below — and for just me, no cap, it is the pick because it delivers:
The head unit is half the bill
Nearly every modern install also needs a dash kit, wiring harness, an antenna adapter ($5-25), and a steering-wheel-control module ($30-60) — most aftermarket units don't retain factory steering-wheel buttons natively. Budget an extra $35-85 in adapters before it will even power on, and confirm your dash opening is double-DIN (~4" tall).
Factory amp / JBL / Bose kills the install
Vehicles with factory-amplified or integrated audio (Toyota Entune, Ford SYNC, Stellantis Uconnect) need an iDatalink Maestro module ($150-250) plus vehicle-specific firmware. Skip it and you lose climate display, parking sensors, OBD-II data, and amp control.
Floating screens are single-DIN behind the glass
The 9-10.1" floating flagships (Pioneer DMH-WT8600NEX, Sony XAV-AX8500) mount a big screen on a single-DIN chassis — the screen juts 1-2" forward of the dash face and can foul HVAC vents, knobs, and the gear selector. Measure clearance before buying.
