I like my old stock head unit because it’s stylish, matches the old classic car and was quality back in its day. Today though… it’s poor sound quality. Ancient paper cone speakers, 4inch in front, 5inch in rear. I inserted the kicker key 200.4 into the system to work it’s electronic magic trickery. Once installed, I used the self-tuning system with the supplied microphone. The results are staggering. Somehow my ancient tiny speakers have acceptably good clarity and even acceptable levels of bass. They are all matched in volume, and the sound stage sounds like it’s right between my ears when sat in drivers seat. Superb product for lifting an worn out old stock system into the present day. Impressed with kicker yet again. Have ordered a set of their entry level speakers now as a follow up from these excellent results. Just a word of warning though… in old cars with earthed negative returns on the speakers, you will need to wire both negative and positive from/to the speakers and cannot earth the speaker inputs to ground. Because It’s a class D amp. (Same with any class D amps, not just kicker). Enjoy. There is also just a whisper of white noise from the amp when powered up, but no music playing. This needs to be improved for future models Kicker! Review: The sound quality improvement is great! - When it arrived it was smaller than I expected which made installing it behind the dash on the passenger side possible (2021 Corolla) I installed this after installing some Focal speakers and the improvement in the sound is great after the auto calibration! ## Features - Don’t just make your system louder - make it clearer Make it better - Press the selector and the microphone goes to work The KEY uses a powerful internal computer to deliver dramatic improvements in realism and soundstage - A massive 40-band equalizer improves tonality and a 24dB crossover re-defines the capabilities of each speaker - The concert quality of your factory stereo is revealed!

I had already changed the four door speakers to Kickers. With the factory deck, there was basically no difference. Once this was added, it sounded close to the quality of my Subaru with a HK premium system less the subwoofer. The auto tuned system works incredibly. It sounds generally so good, I may leave the subwoofer out and reclaim my trunk. It just sounds so great. What a fantastic item. I ended up placing it in my glove box because I couldn't find another good spot for it, but I don't use the glovebox anyway. I did get the wiring harness designed for this and my car off Crutchfield. That was far cleaner as I didn't need to cut the factory harness ## Frequently Bought Together - Kicker 47KEY2004 Car Audio Smart DSP 4 Channel Speaker Amplifier 40 Band EQ Amp - Scosche Install Centric ICAK12 True 12 Gauge Hybrid OFC 2-Channel High Current Amplifier Wiring Kit Accessory Installation Wiring Kit for Boat, Motorcycles, ATV’s and UTV’s - RED WOLF Car Radio Add Amplifier Subwoofer T-Harness Adapter Connector Compatible with Toyota 2018-2023 Camry, 2019-2023 Tacoma RAV4 Corolla Non JBL System Plug and Play --- ## 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.com.pa/products/348218449-kicker-47key2004-car-audio-smart-dsp-4-channel-speaker-amplifier](https://www.desertcart.com.pa/products/348218449-kicker-47key2004-car-audio-smart-dsp-4-channel-speaker-amplifier) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-10-06*
