  • Those sneaky MP3Car folks have a Nano-ITX sized amp in the store!

    Check it out

    Whats the deal with this thing? It has seemingly come outta nowhere but it looks ideal for anyone looking at installing a carPC. Better specs than OEM car audio stuff with a tiny footprint and made for carPC use? Specs say 2x125 or 4x35 so I'd say its an awesome starting point for new install audio.

    And it's only $45. We need a review of this.

      Holy cow... how did I miss this? I think I may have to pick one up for my other car.

        My only complaint about how it's listed is the power being listed in peak. Means nothing. I'm curious as to what the RMS values are on it.
        Play with it, 'til it's broke.

          It is based on the ubiquitous Tripath TA2020 chip.

          The power figures as per datasheet is

          25W @ 4Ω, 10% THD+N, VDD=14.6V
          22W @ 4Ω, 10% THD+N, VDD=13.5V
          13W @ 8Ω, 10% THD+N, VDD=13.5V

          I could see only one TA2020 chip in the snapshot which could power up to 2 channels. Not sure how it can do 4 channels.

          The assembled board looks exactly like those HelderHiFi kits

            My concerns (especially with fitting it inside one of the bybyte cases) are heat and noise. A review would be most helpful. I need two of these.

                  I love the Bybyte double DIN n frame, but there is no way you are going to convince me that a tiny amp at that price point will sound any good.

                    If its the same one they bundle in their case every review i've seen of it has been horrible!

                      I've been wanting to try one of these or the amp9 kits. I have factory speakers so something like this may be ideal.

                        I emailed ByByte a couple weeks ago asking some questions about this amp. I was impressed with their quick responses and attempts to answer my questions, and was ready to buy three of these to power my 5.1 channel system. Then I decided to do more research on the tripath chips and amps made from them. After my research, I got the feeling that bybyte was buying these from another source and didn't actually know that much about them. I don't mean that to be a ding against bybyte, since they really tried to be helpful.

                        This amp is based on a tripath chip, and if you read reviews of amps made with these chips, people are simply amazed at how great they sound. However this particular chip is only two channels, AND for that "audiophile" sound, you're only going to run it at about 12W per channel @ 4ohms. Thats probably enough power if you're replacing a stock head unit, but not really comparable to a typical class a/b amp. Also this amp cannot be bridged to make more power per channel, although outputs can be paralleled to be useful with 2 Ohm speakers.

                        I ended up buying two amp9 basic amps from 41hz.com. The amp9 is 4X100W peak @ 4ohms or 4X50W for low distortion. I felt these would be more suitable to my needs. These come in an unassembled kit. I haven't built them yet, but I know there are others on this forum using them. So cheap doesn't necessarily mean low output or poor quality.

                          yup, same amp on the bybyte site--and i know i have read that the bybte amp is only 2 channel.. the vague description kind of scares me from either site..

                          the amp9 kit would be much better

                          digitalvampire-- that is exactly the kind of info that should be included.

                          i cannot take any amp seriously without actual rms power ratings..

                          even this $20 2 ch. amp from parts express has detailed power ratings, and thd specs in the manual:

                            More details from HelderHiFi who seems to be the original manufacturer of these boards

                            No offense to either Mp3Car or ByByte, but HelderHiFi has been selling this board for ages @ $27.99 (inclusive of international shipping). If I were in US, I'd still buy it from Mp3Car to support the forums.
