Sold by AudioSellerz.com

The Stetsom IR160.2 Wire Input is built for people who want a compact 2 channel amplifier that still gives clean output and useful everyday power, especially in installs using speaker-level input instead of RCA connections. This amp is a strong fit for basic speaker upgrades, simple mids and highs setups, motorcycles, UTVs, tighter dash installs, or any build where space is limited but you still want better sound than factory power can give you. The page keeps it simple with the best summary possible: small in size, giant in power.

Even though it is small, the IR160.2 Wire Input still brings enough output to make a noticeable difference. It is rated at 2 x 80 watts RMS at 2 ohms and 2 x 45 watts RMS at 4 ohms at 13.8V, giving it enough power for many coaxials, full-range speakers, and lighter midrange applications. With wire input instead of RCA, it makes sense for customers working with factory radios or installs where speaker-level input is the cleaner path.

One of the nicest things about this amp is how easy it is to build around. The compact 29 x 58 x 77 mm size makes it easy to hide in smaller locations, while the low current draw helps in simpler electrical systems. Stetsom also lists a greater than 90 dB signal-to-noise ratio and a 35 Hz to 20 kHz frequency response, which gives it enough range for everyday speaker duty without overcomplicating the install. If you need a tiny 2 channel amp with wire input that can still do real work, the IR160.2 is a practical piece.

Whether you are adding power to factory speakers, upgrading a small system, or building a compact daily-driver setup where space matters, the Stetsom IR160.2 Wire Input gives you practical power, simple integration, and a size that is easy to live with.
