Question about Hifonics BX1000D Car Audio Amplifier

1 Answer

No output I have a hifonics bx1000d. problem is little to zero output at the speakers. the amp is used and the previous owner swears it was working when he shipped it out. he has offered to refund my money but that's not the issue here. the amp will power up and stay powered up, no protect light. just the green power led. the protect does come on for a split second then goes off. the amp does not blow fuses or act strange in any other ways just very little output. I'm running a Kenwood headunit and an audio control eqx for the input. I have tried turining the eqx up till clipping and still nothing. I then tried bypassing the eqx and running the input straight off the sub output rca's from the headunit. still nothing. I then re-installed my old school Orion 2150sx and everything works like it should. one other question on my Orion the bolt thru the board got hot an d melted the nylock nut causing the amp to get really hot and the power trace lifted off the board do you think I can epoxy the trace down? I have put a new bolt thru it and it is working pretty good now for a 14 yr old thanks andyj

Re: no output

Have you tried turning up the vol/gain control? Are all the switches on the amp set for full spectrum output? Are you sure you are using the RCA input and not the RCA output jacks (if it has such)? Check all the switches to be sure they are in the "most default" position. Something you might try, is to make a jumper wire to temporarily jump from the audio input ground to the power supply (chassis of car) ground. If this makes it work then you have a input ground problem in the amp. Good luck. P.S. As for epoxying the trace down on your other amp. If the foil is still in good condition then it should be ok to epoxy it down. If it needs some "help" then do that first, then epoxy.

I have a hifonics brutus 1700. I burned one of my subs out the other seems to be okay, but now I have no sound. The protect light doesn't come on and it looks all normal. What can the problem be??

Here's a few things you can do to find out what's wrong ,first make sure you have 12volt on your batt lead and your remote turn on and make sure you have good ground.Take an ohm meter or a 9volt battery and put across/momentary the voice coil on your good sub should read somewhere between 2-8 ohms,if using a battery speaker should pop.if ohms check out or speaker pops your good connect it to your amps output.Next make sure you have a signal to the amp,if you have multiple amps use the rca cable from amp that's working for testing purpose.if all that checks out you'll need to have your amp check by professional

If my amp is rated at 1800 watts rms at 2 ohm. Would it make my memphis 12 hit hard

Depends on the exact model of your speaker and the amp. Most amps are overrated and the spec your referring to is probably the max when hitting. The speaker will probably blow unless your running 2 of them wired in parallel that will give you a two ohm load if the speaker is rated at 4 ohms. You can adjust the output of the amp to keep from blowing them. After everything is installed make sure you car is running and your head unit is panned to just the sub output. Turn the output on the amp to zero. Use the type of music you listen to the most and turn the head unit all the way up. Then turn the amp output up until the subs start to distort then back it down a little. In this way you shouldn't blow the speakers. Also the box design is important. I have found most speakers have a web site that will give you specks on a box design. ported, sealed and the like.

Why does the hifonics bxi1608d 1600 watt super D-class mono have 2 postive terminals and two negative terminals? would that cause my speakers to blow?

That is still a single channel cass D amp. Each (-) and each (+) terminal are connected so its actually like only having one. This is so you can hook speakers up in a series circuit to lower impedance, because this amp is 1ohm stable. What causes your speakers to blow is too much power. What kind of speakers are you running? This hifonics amp is very powerful, they are getting big in the competition industries beacuse they put our true power for less money and they are tough. That 1600 amp you have may be putting out more like 1800 watts at 14.4 volts which is 900 per sub at 1ohm so be careful this amp has tons of power and its true rated its not like a sony or rocksford or kenwood that says 1800 max and then in small writing it says 500 rms. This amp puts out true. I have 3 hifonics amps and love them.

Hifonics BXI 1606D problems

it may be a wiring problem you need to make sure all the speaker positives and negatives are correct. I sell alot of hifonics amps and have never had 1 do that. it may also be a bad rca cable. if it only does it when you use the filter i would say not to use it also make sure the gain is no more than 3/4 turned up and the bass boost no more than 1/2. if you have a dif amp try a temp setup using it and if it still does it its a wiring issue. also try 1 speaker at a time on the hifonics and keep adding 1 till it comes back it may be a bad voice coil on 1 sub .

It's likely that the amplifier has shorted output transistors. If that's the case, they will have to be replaced. If you have zero experience with electronic repair, you should pay someone to repair it instead of trying to repair it yourself.

Let me know if you have any other questions.

Hifonics Taurus circuit diagra???

You need to measure the voltages at the output transistors. The previous "driver" stage may have a problem. These outputs use .6V as the bias differential. Check for DC voltage on the inputs to the transistors. These are standard designs. I'd check for DC anywhere along the signal path.

Problem with hifonics 1505 class d mono

The positives are connected together and the negatives are connected together. The two pairs of terminals are for convenience. You'd connect one speaker to a pair of positive/negative terminals and you'd connect the other speaker to the remaining pair of positive/negative terminals.

You need to confirm that you have a good signal feeding the amp. If you have another amp in the vehicle, swap the RCA cables between the amps to see if it makes a difference.

You also need to confirm that the speaker are working properly and that there are no broken connections in the wires. If you disconnect the speaker wires from the amp and touch the wires across a D-cell battery (for a fraction of a second), the speaker should pop. if it doesn't, check the wiring to determine why.
