  • Bybyte.com's DTA45 Amp Good or Bad?

    I have little knowledge of amps and i was wondering if anyone has used this one yet?

    Features:

    ●12V DC @ 3.5 AMP Single supply operation

    ● 110mm (L) x 63mm (W) x 30mm (H)

    ● Can be connected directly to the board's audio headers
    ● “Audiophile” Quality Sound
    ● High Power Class T architecture
    ● High Efficiency
    ● Dynamic Range = 102 dB
    ● Turn-on & turn-off pop suppression
    ● Over-current protection
    ● Over-temperature protection
    ● Strong enough to power 4x45 watt or 2x75watt speakers

    ● Dynamic Range = 103 dB
    ● Up to 2X25Wrms @ 4Ohm, VDD=14.6V
    ● Mute inputs

    It says Strong enough to power 4x45, would that be 4 channel or still 2 channel?
    Would i need to buy two DTA45's in order to have 4 channel?

    Also is there an easy way to see what wattage my stock speakers are? (98 Volvo s70)

    Thanks for helping a noob in advance.

    i am just not crazy about that amp..

    it is only 2 ch, so you need to understand series/parallel wiring to get a correct end-load on the amp..

    and it's class-t architecture means that it has a higher thd then a class-d or a/b amp, which rules it out as a "audiophile" quality amp...

      Hmm

      what do you think of the amp9 from 41htz?

        -The class of the amp has nothing to do with what makes it "audiophile". I would prefer no company to ever use the term audiophile to sell something. If you are into audio, you are an audiophile by definition.

        -THD is always dependent on the power level. All amps have varying THD levels and as you reach the limits of output power the THD will skyrocket during clipping. No amp is immune to this.

        The real question is, does it have enough power to avoid clipping for someone's use? For the people who are satisfied with a typical aftermarket headunit power amp, most likely yes.

        They have a weird way of trying to market their product with the wording. I only see 2 channels.

            With 42W input @ 12V (and possibly 50W @ 14.4V), hence a likely max output of 30W to 45W, "Strong enough to power 4x45 watt" means just that. (I refer to RMS values - peaks etc are meaningless unless perhaps defined and substantiated.)

              I've been working with Amp9-BASIC amplifier from 41hz. I bought it pre-assembled. The sound quality is pretty good, although I don't have any high-end speakers to hook it up to. It goes pretty loud - I might have to put a limiter on volume in Windows so I don't accidentally turn it up all the way and blow out the speakers. Also, the amp accepts variable voltage (12-27) so you don't need a voltage stabilizer (although I bet it couldn't hurt). All in all, I'd recommend it - just make sure to install a big enough heatsink on it.

                Amp9

                I have been unable to find the pre assembled amp9, there out of stock and have been for awhile at 41htz.

                Does anyone know where else to get one? (assembled)

                  Looks like the DTA45 should be the next item i do a product review for. There's a lot of information on the board about it, but it seems for the most part negative and "specification" based. Lemme see if i can get one and compare it to my current audio setup.

                    I agree with soundman, that if you have 4 speakers, it's better to just get a 4 channel amp. However, to be fair, the only "i've used it" response regarding dta45 indicated that it was pretty good.

                      That would be cool!

                        I actually have 8 speakers in my vehicle, i just cant seem to find any specs on the speakers (i read all the speakers have 8 ohm's of resistance)?
                        Kind of odd to have 8 ohm speakers.

                          You can still power 8 speakers from that amp, I think, if you connect them serially (if that's even the term applied to amplifiers).
                          I'm not very knowledgeable with amps, but I zoomed in on the DTA45 and it's a tripath 2020 chip, same chip that 41hz uses in 2 channel amps (amp6 i think). But a good chip cannot save an otherwise bad design, so I can't say anything about dta45's sound quality. I'm looking forward to Sonic's review.

                            most cars use 2 or 4 ohm speakers, but there is no standard procedure, or spec for this, so car makers can use anything they want..

                            yes, you would need to connect everything in series, and parallel to get the correct load on the amp-- you really need to familiarize yourself with the way that multiple resistances react in different connection methods to fully understand the correct connections..
