Alpine iLX‑W670

$350
typical price on Amazon · in stock · crept up from an earlier-2026 low
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.

Alpine iLX-W6707-IN · 13-BAND EQ · SHALLOW

Fit ledger — need → measured evidence

DSP TUNING CONTROL
13-band graphic EQ, 6-channel time correction, and front/rear/sub crossovers — the tuning depth an SQ build needs from the head unit.
SHALLOW DASH / HIDDEN AMPS
An ultra-shallow PowerStack chassis mounts Alpine power packs directly behind the radio — fits dashes deeper units won't.
CLEAN AMP FEED
6-channel 4V preamp outputs feed a multi-amp, multi-way active system.
BARGAIN SQ CHASSIS
At ~$350 it's the cheapest DSP-capable audiophile chassis here — a strong value even after creeping off its low.
OEM & SWC OPTIONS
The W670-M ships Maestro-ready and the W670-S bundles a steering-wheel-control adapter.

  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:

DSP tuning control Shallow dash / hidden amps Clean amp feed Bargain SQ chassis OEM & SWC options
Trap 01

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).

Trap 02

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.

Trap 03

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.
