@Chagrin223 4 месяца назад

@91lrrrc 4 месяца назад

@@Chagrin223 not one channel but one pair of channels (as we are talking bridged) per voice coil yes. Gain should be set to match the pair of channels with least output. This way its same power on each coil and it’s not clipping on one pair of channels when another is clean. The slight difference in power tho on a coils wrapped around same former really shouldn’t be a big deal but it’s best to do it correctly anyways. Would be good idea to use RCA cable splitters into front and rear channels if there is any chance of hitting fader control on source unit.

Amazing, ultimate work truck amp! Now I can start adding Savard subs to my fleet 😂 The size reminds me of the paperback Sony 2-channel that everyone was running their tweets with in the late 80s, maybe 20 watts per? Can't remember. I know this is off topic but I went with your recommendation on the Dual Wal-Mart $24 stereo. Paired with a set of $36 CT Sounds BIO 5.25" coaxs from Amazon, it floored me how clean & loud it plays in my rollback. Plays Steely Dan perfectly at 35 on the volume, bass set at 5, treble at 7. Absolutely no muddiness & plenty loud enough to cut thru the noise of the truck. Shockingly good sounding for $60! You're the best Big D! 👍

Its amazing how cheap and good amps have become, I bought a 100 dollar 1200 watt Jensen amp from Walmart, and I been bumping it full capacity for months and it hasn’t let me down, and it has a 3 year warranty. Like what?! Oh yeah and it has bluetooth settings and led lighting.

that amp ic is 100% a TPA3255 , the power , the board layout screams tpa3255. they are running it at lower voltage or the powersupply is weak because it should do 250w ch at 4ohm with +- 50v

@mattliston1215 4 месяца назад

Are you saying if one were to wire in a voltage booster inline with this amps power input, it would enhance it, that is, if there is no onboard ciruitry blocking it from working?

@zeptoplix 4 месяца назад

@@mattliston1215no, internally the rail voltage is operating lower than the maximum rated by the tpa3255. It would not be easy.

@KuntalGhosh 4 месяца назад

@@mattliston1215 you would have to bypass the internal power supply , they are limiting the power to keep the heat down as it would cost a lot more to keep such a tiny chip cool when it dissipates 30-40w while making close to 300w per channel. that would require a heatpipe and finned copper cooler.

@samohraje2433 3 месяца назад

⁠actually i do have an amplifier with 3255ic and OH man.... that thing at 50V banging like crazy. Technically it is 600W mono IC but in the real world, you can aspecting it more likely to be around 400 BECAUSE, i do have a subwoofer as well rated at 500W RMS and after playing like decaf or rebassed songs, i can't smell it. I tryed even 400W subwoofer and also no smell so there's 2 options... they are good ventilated, good made or the 3255ic can't do much to start them to smell.. but anyways, really good ic, for the price, the best. My amp is mixture of one tpa3255 for the bass and two TPA3221 which gives you 4 channels, 100W for each one or two channels 200W each, you can bridge them. That amplifier has internal DCDC buck converter because supply voltage is 51V and those two tpa3221 can not handle more than 30. For the indoor or outdoor usage, excellent.

@KuntalGhosh 3 месяца назад

@@samohraje2433 not just voltage. There are many factors effecting total clean power output. Most chinese boards are poorly designed they copy and paste the typical application diagram while swaping components to reduce cost and do not follow all the datasheet rules. Even though the chip can provide 600w at 10% thd pbtl with i think 2ohm load. It will not produce that power with a poorly designed board with thin traces, cheap capacitors , and simply not enough capacitors.

@10100rsn 4 месяца назад

The appearance of the chip and the circuit board layout says to me that its a TPA3255. Given the test results they might be rating it by peak power draw and not RMS output. It looks like there is a voltage boost circuit on the power input side of the board. I wonder if the voltage is actually boosted all the way to 48v? idk, it could be current limiting in the chip, too.

@paulchristman5875 4 месяца назад

Is it because the default low pass is on which automatically engages the low boost at 45hz making it appear much more powerful than it really is? Usually you test things for us with all boost settings at zero. ❤❤
