You are limited by the power spec of 3 Watts. To calculate the max voltage use this equation: P = V x V/R. Solving for V, one gets V = sqrt(P * R). So, for these speakers you get V = sqrt(3 watts * 4 ohms) = sqrt(12) = 3.46 volts. The thing to remember is that the 4 ohm "resistance" should be considered as an impedance value. That is it will most likely be a some combination of the DC resistance of the voice coil and the AC reactance of the voice coil measured at 1000 Hz, which is sort of a standard. The thing you want to consider is that at lower frequencies, the AC reactance will decrease and for a given voltage, the current will increase and thus the power rating can end up being exceeded. At higher frequencies the AC reactance will increase and for a given voltage, current will decrease and power will go down. Generally, the power rating for a speaker is determined by how hot the voice coil can be allowed to get before it fails. I have used these with a small 5 volt stereo Class D amplifier rated at 3 watts per channel. With a reasonable enclosure they sound pretty good and can provide plenty of volume considering their size. I hope this helps. **Q: Is one of the dimension really 4.5 inches** A: No, the speakers are 2" x 2". The "4.5 x 1.1 x 2.5 inches" in the product description is for the package containing two speakers. **Q: If I use this to replace 4 ohm computer speakers driven by 8w amp and keep volume well below max will I do damage?** A: Probably no damage unless you hit them with more than 4 watts of power. **Q: Are these speakers waterproof** A: No. I never tested them, but they don't look like other waterproof speakers I have seen. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by Z***Y on October 31, 2025* ### ⭐⭐⭐⭐⭐ Review *by C***T on January 6, 2026* ### ⭐⭐⭐⭐ Review *by D***R on March 11, 2024* ## Frequently Bought Together - Gikfun 2" 4Ohm 3W Full Range Audio Speaker Stereo Woofer Loudspeaker for Arduino (Pack of 2pcs) EK1725 - DFPlayer - A Mini MP3 Player - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## 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.pl/products/32098629-gikfun-2-4ohm-3w-full-range-audio-speaker-stereo-woofer](https://www.desertcart.pl/products/32098629-gikfun-2-4ohm-3w-full-range-audio-speaker-stereo-woofer) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-10*
