Sounds good for my jeep. ### ⭐⭐⭐⭐ Review *by B***4 on 30 October 2024* Sound quality is OK. For its size and price it's pretty good. ### ⭐ Review *by A***W on 7 August 2024* It seems to be good build quality and it has a year warranty but when I hooked my unit up I could not get any sound. I contacted tech support and they verified that my install was correct and got me to contact their warranty department. Waiting to see if they are going to send me a new unit or if I will have to return mine to be fixed. Update: they wanted me to send in my amp for repair which I ended up having to pay the $30 shipping fee for. Now my unit is in the USA and they informed me that they do not ship to Canada. They sent it to one of their distributors to ship to me and that was 4 months ago and I still have not received my amp back. I am $70 plus $30 for shipping into an amp that showed up defective and now I don’t even have it as a paper weight. ## Frequently Bought Together - PRV Audio QS400.4 2 Ohm Mini Compact 4 Channel Car Audio Amplifier 4 x 100 Watts RMS at 2 Ohm - 400 Watt Amp Stereo 12 Volts Amp Class D Full Range Bridgeable - PRV AUDIO Super Tweeters for Car Audio, 3.5 Inch Bullet Tweeter Pair 240 Watts, PRV Tweeter TW350Ti-4 Slim Titanium Bullet PRO Shallow Tweeters Speakers 4 Ohm - Ultra Slim Easy to Mount --- ## 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.dk/products/659590714-prv-audio-qs400-4-2-ohm-mini-compact-4-channel](https://www.desertcart.dk/products/659590714-prv-audio-qs400-4-2-ohm-mini-compact-4-channel) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-05-12*
