Review: This is a excellent amp. Great value at ₹8K - For ₹8K this is an excellent amp. Powerful. Lives up to it's rating of 70W pc and has a warm, rich sound. It is nicely styled but this is irrelevant as it goes under the seat. Connectivity is good and it can be tuned to some extent. It will sound as good as your speakers, though with the Infinity REF6520CX (asli maal $180 in the US!) will sound magnificent. Those are hard to get here and very expensive here. I'd have bought the Morel Maximo 6 Mk II if it were in my budget. If you like colourful, saturated sound, buy this with JBL or Sony component speakers. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BBLCTJTF | | Best Sellers Rank | #560,563 in Electronics ( See Top 100 in Electronics ) #57 in Car Multichannel Amplifiers | | Brand | Infinity | | Brand Name | Infinity | | Colour | Black | | Compatible Devices | Car Audio System, Headphone, Speaker | | Connector Type | RCA | | Customer Reviews | 3.7 out of 5 stars 20 Reviews | | Item Package Quantity | 1 | | Manufacturer Part Number | 1 | | Model Number | Infinity Alpha 2804a | | Number of Items | 1 | | Number of Ports | 4 | | Smart Home Compatibility | Not Smart Home Compatible | | Specific Uses For Product | Car Audio & Video | | UPC | 050667378899 | | Unit Count | 1.00 Count | ## Product Details - **Brand:** Infinity - **Compatible Devices:** Car Audio System, Headphone, Speaker - **Connector Type:** RCA - **Number of Ports:** 4 - **Specific Uses For Product:** Car Audio & Video ## Images ![Infinity Alpha 2804A Car 4 Channel Amplifier (70W RMS*4) || NEW 2022 MODEL - Image 1](https://m.media-amazon.com/images/I/41rihJFZIeL.jpg) ![Infinity Alpha 2804A Car 4 Channel Amplifier (70W RMS*4) || NEW 2022 MODEL - Image 2](https://m.media-amazon.com/images/I/21r9ObScTSL.jpg) ![Infinity Alpha 2804A Car 4 Channel Amplifier (70W RMS*4) || NEW 2022 MODEL - Image 3](https://m.media-amazon.com/images/I/21iuX-fKXVL.jpg) ## Questions & Answers **Q: It is supports fredo dvc12frd 12 inch dual coil/double magnet 2 ohms to 8 ohms subwoofer yas or no** A: Yes **Q: Sony subwoofer 1800 watt and 2 pioneer speaker mentioned 650 watt can be connected for a good crystal sound with this Amp .
