Optional VCR-S2 Remote Volume Control (Sold Separately) Review: Audison SR 4.500 4 Channel D-Class Amplifier 880 Watt Amp SR4500 - The Audison SR 4.500 is a compact, efficient 4-channel class-D amplifier that punches well above its size. With 130 W × 4 at 4 Ω (and 220 W × 4 at 2 Ω), it offers clean power and tuning flexibility in a small footprint. The passive cooling design kept it quiet and reliable, even under load. Input flexibility (RCA + speaker-level) and features like ART and USS make it easy to integrate with both factory and aftermarket systems. In listening tests, it stayed clean to high volumes, handled dynamics well, and offered precise control through its built-in crossovers. It’s not a heavyweight sub amp, but for driving speakers, it’s a strong performer. Great choice for serious car audio builds without going overboard.” Review: Audison FTW!! - Small and compact can easily fit anywhere and provide true power for my speakers. Not only that, the hi-res audio makes them come alive. ## Features - Bass Boost 50Hz (adjustable) B Ch (0 ÷12) dB - Inputs: Pre-In / Speaker - In Outputs: PRE OUT Full range (Input A) - Front Ch Filters: Full Hi-pass: 50 ÷ 3.2k Hz @ 12 dB/Oct.

Not only that, the hi-res audio makes them come alive. ### ⭐⭐ Audison Disappointz *by J***Z on April 29, 2026* It’s a decent four channel amplifier I suppose but it’s nothing like equipment made by Audison or Hertz in the past. I am really unimpressed with the performance. After all, 400W really isn’t that much to ask for. ## Frequently Bought Together - Audison SR 4.500 4 Channel D-Class Amplifier 880 Watt Amp SR4500 - Audison SR1.500 D-Class Amplifier Mono Amplifier 1Ω 1000 W x 1 SR1500 - Audison SR 4.300 4 Channel D-Class Amplifier 4X85 WRMS at 4 Ohms SR4300 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ec/products/230098031-sr-4-500-4-channel-d-class-amplifier-880-watt](https://www.desertcart.ec/products/230098031-sr-4-500-4-channel-d-class-amplifier-880-watt) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-06-16*
