    • 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.” ... show more

    • 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.

    • Audison Disappointz
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.

It's good so far, just not enough power to run all 4 doors. I have American Bass Godfather 6x9s in the front and Godfather carbon 6.5s in the rear I'm going to bridge the amp for better power at the front doors. And strap a second amp for the rear doors. The amp does make a buzzing noise that quiets the lower you turn the gain. But the power is clean This is getting really expensive 😵💫😵💫 ... show more

    • This Amp. has it all !!!
This little amp is amazing!!!!!! Compact, easy to install, I ran it hard did not overheat, so the specs on this unit must be true. Sound quality is fantastic. I will never buy another amp. from any other company. This amp is for real.
