Why Choose This Product?
The Q1-4500v2 combines a Korean-built board with a wide working-voltage range and multiple power ratings. Its adjustable filters support system tuning, while the compact chassis gives you concrete dimensions to consider when planning an installation.
The amplifier is designed for high-power subwoofers in the 1,500–4,500W RMS range. SoundQubed’s HDX and HDS series are identified as pairing options when wired to a 1Ω final load.
Installation & Compatibility Notes
Rated-power operation requires a properly upgraded electrical system. The stated requirements are a high-output alternator, an upgraded under-hood battery, and 0-gauge power and ground wiring. Reaching the full 7,140W rating at 18V requires a high-voltage electrical system with lithium or AGM reserve batteries.
For most ported SPL builds, the source recommends setting the low-pass filter between 50–80 Hz and using the subsonic filter below the enclosure tuning frequency. A dash-mounted voltmeter is strongly recommended. Consult a SoundQubed dealer or professional installer before purchasing.
Frequently Asked Questions
What power does the Q1-4500v2 deliver at 1 ohm?
It is rated at 4,670W RMS at 14.4V, 5,640W RMS at 16V, and 7,140W RMS at 18V.
What subwoofers can I pair with this amplifier?
The source recommends subwoofers rated at 1,500W RMS or more, including the SoundQubed HDX3.2, HDX4.2, and HDS3.3 series. Multiple subwoofers can be wired for a 1Ω final load.
What electrical upgrades are required?
For rated power, plan for a high-output alternator, an upgraded under-hood battery, and 0-gauge power and ground wiring. Full 18V output requires a high-voltage system with lithium or AGM reserve batteries.
How can I tune the filters for a ported SPL setup?
The source recommends a 50–80 Hz low-pass setting for most ported SPL builds. Set the subsonic filter below the enclosure’s tuning frequency.
Can I use it for daily listening?
The source describes the Q1-4500v2 as designed for daily use as well as SPL builds, with the proper electrical system.
