SOURCE: amp getting really hot

If depends on what the amp is rated to run. If it is only rated to run 2 ohms x2ch then it can only run 4 ohms x1ch. If you run it at 1 or 2 ohms that is too low, too much current, and it will get hot and eventually blow up under hard use. Some quality amps can live that way, and it depends on the sub and what frequency you are running it at. For normal use I would not recommend it. Wire to sub at 4 ohms x1 (or 2 ohms x2ch) for that amp if that is what it is supposed to be at, I'm not sure from your description. Also enhance cooling of the amp if you can, I run fans on mine if they have a heat issue. Warm is one thing, hot is another and not good for amp.

SOURCE: XX- ZEUS MONO D- CLASS / 1600 WATTS RMS

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.

SOURCE: Connecting a subwoofer to a mono amp that has 2 sets of terminals

ok this gets confusing sometimes. Ok first look to see what ohm your subs are. If you have a dual 4 ohm sub When you run that on sub + to + and - to - then that will make that sub 2 ohm. its different on ohm if the sub is say a 8 ohm then putting the wires that way will bring that sub to 4 ohm. Now lets say you have 2 subs that are dual 4 ohm and wire both of them + to + and - to - and go bridge the amp which would be both wires from sub both + together and both - wired bridge on the amp will make it a 1 ohm to the amp. Please post what ohm your subs are and i can tell you alittle more about it

SOURCE: why does the hifonics bxi1608d 1600 watt super

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.

I have 2 Pioneer TS-W3002D4 12 In and a Hifonics Brutus BRZ1200.1D D-Class Mono Block what's the best wiring


you need to wire each sub down to 2ohms then wire them together like the one in this pic http://m.seimg.net/product/img/subwoofer_wiring/2_subs_DVC_4_ohm_mono_variation2.jpg witch will give you 1ohm so you will be getting every bit of power that amp has but you should get a bigger amp for thos speakers

Hi I have just bought a Sony 820av amp and tannoy sfx speakers. I have got all working except my sub. Can anyone advise me on correct cabling for the sub to amp?


Sub woofers are just mono amps. They feed both the right and left output together. So all you need is a stereo to mono cable. The two jacks go in the sub and the single mono into one of the terminals on your amp. The other terminal will allow another sub to be connected I think, though please check your manual for this.

Hifonics colossus-ltd dual monoblock amp does not have much output, running a cerwin vega stroker dual 2 ohm sub wired 4 ohm load bridged


Bridge at 4ohms your only getting 600watts rms. You will need to bridge at 1ohm (parallel) and adjust the gain accordingly. This will give it 1600 watts rms. If you would of had a dual 4ohm sub, then you could of bridged it at 2ohms mono, but you can't you have to go either 1 ohm or 4ohm. I believe it's not getting enough power.

How do i connect subwoofer (canton movie 125 mx) to amplifier(onkyo txnr609)? there is one subwoofer output on the amplifier with either L & R(mono) high level input or L & R(mono) low level input...


Connect front the sub out (single) on the amp to one of the rca inputs on the sub, This will work reasonably well but to make the most from the sub buy a 2 rca to 1 rca cable and use it to connect both rca inputs on the sub to the single output on the amp

I have bought JAMO sub 250 subwoofer and Pioneer VSX919AH-K amp. Please advise how can I connect them. The amp has one RCA out for sub but the sub has two line in sockets (left and right). Do I need to use...


Hi,
You don't need such cable, although you can use it if you have one. If receiver has only mono SUB output (as majority of receivers have), you just connect it to the Left socket on the Sub and it will work.

Using the Y cable would probably cause that you will fed the same signal to both left and right sockets, but half the intensity (you would divide the output from receiver by 2). So in the end the Sub would receive exactly the same signal as when using normal straight cable.

That's dependent on your subwoofers. You will need 2 dual 4 ohm subs wired in Parallel, a single dual 2 ohm subwoofer wired in parallel, a single dual .5 ohm wired in series. Or something similar.

How i wire my sub to my jbl gto301-1iiamp with 2 Hifonics HFi12D4


If the amp is 1200 watts at 2 ohm stable you will want to set up the speakers as parrallel and bridge the amp. That means conncect the speakers with + to + and - to -. Look at the amp connections. Usually thereare connects that look like this:
+ -
+ - + -

If yours look like this use the diagram on top. You will use the + for the left ouput on the amp to the right - on the amp. This will allow you to use all the power from the amp. Be sure to lower the gain as to not pop the speakers or amp.

Wiring options


Hello chino2g,

For 3 DVC 4 ohm subs wired to a 2 ohm stable amp, your best option would be to wire all of the sub voice coils in series (individual 8 ohm loads) and then parallel the three subs for a final load of 2.67 ohms. There's really no other configuration. Here's the wiring diagram:

Hope this helps.
