Why does my boss 1600 watt diablo amp cut off at high volumes

Chances are your speakers are running at to low of impedance. Check if your running aftermarket. speakers, if so they are probably wired in parralle. Change the wiring to "series"increasingly your impedance from 2ohms to 8, that should solve your issue.

BOSS AUDIO SYSTEMS SE950 Car Audio Amplifier: I have a SE950 boss amp, hooked to 2 audiobahn 12"...

Sounds like you are over working this amp for sure.. Upgrading your power wire & battery might help, check your gain level on your amp to. This is not the volume for the amp. Its to get both amp and the cd player on the same page... And most of all if your subs are wired up to .5 ohm stable, see if your amp do the same... My answer to this ?? Upgrade your amp, Boss audio was never a good company to me, but that is my opinon. Audiobahn set up all the way..

Turn off boss RT-735 CAR AUDIO AMLIFIER??

If you want to turn it off - Simply disconnect the remote wire or pull the fuse.

If it is turning off - there is a problem. Thermal shutdown, Grounded Voicecoil or wire, or load us under rated impedence.

Disconnect the subwoofer and power up the amplifier.

Any repairs will have to be from a service center, as repair parts and diagrams are not available from BOSS. The repar may end up being more than a replacement would cost.

What is the wire diagram for the 3way bx35 boss crossover

Hello rew_smith,

The wiring diagram is silk screened right on the top of the unit. If your diagram is missing or obscured, you can get one directly from

The first 3 pairs of connections for subwoofer, front, and rear inputs coming from your receiver or head unit. Top is left channel, bottom is right channel. The 2nd set of connections are the outputs and matched in function to the first set. These are connected to your amp(s).

To the right of the input/output connectors are the 12V +, remote and ground screw terminals. The 2 switches and 9 controls allow you to set the high-pass frequency and output levels for the front and rear channels, and the crossover frequency, bass boost, phase, and output level for the subwoofer.

Hope this helps.

I have a Boss OL5KD Class D Monoblock Amplifier and I set it up but is no sound coming up from the speakers, can anyone tell me how to higher the volumen? where is located the volumen??I need to higher the...

Hello maydude01,

The Boss OL5KD does not have a volume control. It has an "Input Level" adjustment which is used to match the output from your head unit preamp output to the amp. It is the first rotary control just to the right of the input jacks.

If you have no sound at all, I'd suspect that something is incorrectly connected or there is no input to the amp. First make sure that the amp power light (green LED) is coming on when you turn on the receiver and that the protection light (red LED) stays off. Then check all of your wiring, especially the RCA output cables.

Initially set the controls like this: MASTER/SLAVE switch in MASTER position (left). INPUT SENSITIVITY 2v-8v (right). INPUT LEVEL, SUBSONIC FILTER, BASS BOOST, and LOW PASS FILTER; midrange. PHASE SHIFT "0" (left). Leave the remote level control disconnected.

After you've checked all wiring and initially set the switches and controls, turn the receiver on to about 3/4 volume. Now adjust the INPUT LEVEL to the left just until you begin to hear distortion, then turn it back right just a little. Adjust the other controls for best sound. Plug in the remote level control and make sure that it adjusts the bass up and down. You're finished!

If there's still no output from the unit after checking all of the wiring, either the unit is defective, it's not getting an input from the receiver, or the sub(s) are defective.

Hope this helps.

Adding subwoofer

Hello dongurian,

You can add the Bass600 even if your Pioneer does not have any premap outputs. The Bass600 has speaker level inputs and you should have gotten a keyed plug with pigtail wires to attach to the speaker output. Or, you can use a line-out converter if desired.

Hope this helps.

I need to know how to install a Boss Audio

Hello viperman2004,

Just connect your speaker leads to the input of the B65N (gray and gray/white pigtail leads), run the RCA cables to your amp (red=right) inputs, adjust the left and right level controls to match the amp input without distortion, and mount the unit.

Hope this helps.

Sony xplod amp xm-1652z high level input connection

First off, if you're using RCA preamp connections from the head unit to the amp, you don't need to put anything into the high level input connector. But if your head unit doesn't have RCA preamp outputs, then connect the front left to the white (+) and white/black stripped (-) wires and the front right to the grey (+) and grey/black stripped (-) wires. There is no need to connect the rear speaker outputs of the head unit to the high level input of the amp.

First problem is that if you ever have a problem with anything electronic you dont ignore it going on and off or you dont hit it to get it to start working. Thats a true indicator that something is wrong and/or somethings about to break and take everything with it. When it first started to go on and off You could have made sure that the speaker lines were not loose or touching one another or another big problem like this is the speaker wires and how they are ran thru the vehicle sometimes the vibration will rub off the insulation and /or pinch the wire and short it out agains the chassis of the vehicle. The best way for you to trouble shoot this is to first have someone check the speakers and lines. Make sure the inputs are good and disconnect the output lines(speakers wires) from the amp and put a dc meter on one of the outputsw. And have someone turn o0n the power. If theres any dc there for even a spit sec then the amp has blow output devices and probably also bad drivers and predrivers. At this point find out how much your local repair person would charge you for an estamate. or contact Boss at 323.890.3700 ext. 2770 Good Luck
