I chose this one because it already had the speakers included. It is not easy to choose the right speaker for an amplifier since the amplifiers have RMS and nominal power, which changes if the speaker is 4 or 8. It is not easy to choose the right speaker, so I thought it was very good that already the amplifier will bring the speakers. Less task to acquire the whole set. I was surprised by the size of the amp. It is really small. I thought the sound would not be that good, but I was wrong. The sound surprised me! It is very good! My boat is a 21-foot bowrider type and with the engine running the old audio system just couldn't be heard, so I decided to change it for a better system, and this one works well. Pros: - The small size of the amp really makes it easy to hide it inside the boat - Bluetooth connection is extremely easy - The controls screen facilitates everything - It is a totally marine product - The speakers are easy to install and have the patterns to make the holes. - The USB connector is very good. Read MP3. - It is a very practical system and the sound is very good. Now my friends call it "the party boat" :) - the price is right. Cons - I don't have any for now. ## Features - BOSS AUDIO ASK904B.64 Marine Package Includes 500 Watt Max 4-channel Bluetooth Amplifier, Two Pair 6.5 inch MR6W Marine Speakers, Universal USB cable and Phone Pouch - 2 pairs of speakers ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00VFZ09TG | | GTIN (Global Trade Identification Number) | 00791489123020 | | UPC | 791489123020 | | おすすめ度 | 5つ星のうち4.4 611 レビュー | | チャンネル数 | 4 | | ブランド | BOSS Audio Systems | | ブランド名 | BOSS Audio Systems | | メーカー | Boss Audio Systems, Inc. | | メーカー名 | Boss Audio Systems, Inc. | | モデル番号 | ASK904B.64 | | 取り付けタイプ | シーリングマウント | | 商品の重量 | 10 ポンド | | 商品寸法 (長さx幅x高さ) | 19.1 x 13.5 x 4.3 cm | | 商品本体サイズ | 19.1 x 13.5 x 4.3 cm | | 電圧 | 12 ボルト | | 電圧（ボルト） | 12 ボルト | ## Product Details - **Item dimensions L x W x H:** 19.1 x 13.5 x 4.3 cm - **Voltage:** 12 Volts - **Manufacturer:** Boss Audio Systems, Inc. - **Mounting Type:** Ceiling Mount - **Brand:** BOSS Audio Systems ## Images ![BOSS AUDIO ASK904B.64 Marine Package Includes 500 Watt Max 4-channel Bluetooth Amplifier, Two Pair 6.5 inch MR6W Marine Speakers, Universal USB cable and Phone Pouch by BOSS Audio - Image 1](https://m.media-amazon.com/images/I/81-CElty91L.jpg) ![BOSS AUDIO ASK904B.64 Marine Package Includes 500 Watt Max 4-channel Bluetooth Amplifier, Two Pair 6.5 inch MR6W Marine Speakers, Universal USB cable and Phone Pouch by BOSS Audio - Image 2](https://m.media-amazon.com/images/I/A1W8ynU53sL.jpg) ![BOSS AUDIO ASK904B.64 Marine Package Includes 500 Watt Max 4-channel Bluetooth Amplifier, Two Pair 6.5 inch MR6W Marine Speakers, Universal USB cable and Phone Pouch by BOSS Audio - Image 3](https://m.media-amazon.com/images/I/81kaZxPmKRL.jpg) ![BOSS AUDIO ASK904B.64 Marine Package Includes 500 Watt Max 4-channel Bluetooth Amplifier, Two Pair 6.5 inch MR6W Marine Speakers, Universal USB cable and Phone Pouch by BOSS Audio - Image 4](https://m.media-amazon.com/images/I/81MSq4tVymL.jpg) ![BOSS AUDIO ASK904B.64 Marine Package Includes 500 Watt Max 4-channel Bluetooth Amplifier, Two Pair 6.5 inch MR6W Marine Speakers, Universal USB cable and Phone Pouch by BOSS Audio - Image 5](https://m.media-amazon.com/images/I/71dNjeh8sgL.jpg) ## Questions & Answers **Q: I hooked this system up in my boat. It works great until i turn the boat motor on. Then it cuts in and out continuously. Ideas what might be wrong** A: I’m having the exact same problem. With te engine off it works just fine but ad soon as I turn the engine on in cuts and turns off. I made a completely separate cable and connection straight from the battery and the problem persists. I have a voltage gauge and volts go from 12.6 with the engine off to 14.4 with te engine on which is just fine. I even changed the voltage rectifier in my engine but the problem persists. Its definitely a problem with the amp. **Q: If i install this without a head unit can i control the fade and balance with the inline multi-function remote?** A: Not as far as I know ! **Q: What is the rms of the speakers?** A: 10 **Q: Will the unit still work from a smart phone if the remote gets lost or broken.** A: The remote is hardwired, if you lose it will not function ## Customer Reviews ### ⭐⭐⭐⭐⭐ Chulada *by K***. on 2021年5月15日にメキシコでレビュー済み* Exelente producto lo recomiendo se lo puse a una Road king y se escucha muy bien ### ⭐⭐⭐⭐⭐ Good Product! *by B***S on 2021年8月5日にアメリカ合衆国でレビュー済み* After evaluating many options on the market, I bought this amplifier, read many reviews, and compare different options.
