Boss 3500 Watt Monoblock Amp stops putting out signal

I have a Boss 3500 watt monoblock amp that works when the car is turned off but as soon as I start the car it stops putting out any sound. The amp is wired up to a 10 Farad capacitor that is wired up directly to the battery thru a stinger 200 amp solinoid switch that is used to turn on the amp and capacitor.

    I have a 1960's car with the same amp and im having the exact same problem. The amp works great with the car off, then as soon as I start the car, the amp quits...any ideas as to what your problem was?

What's the battery voltage across the B+ and ground terminals of the amp when the engine is running?

Does the amp go into protect mode when the engine is running?

Are you sure the head unit is still producing output when the engine is running?

Can you use a bazooka ba1150 to power up an infinity 1230w sub? not a techie just happened to have these two items and was wondering if i can use them together. thanks.


This is an 150 RMS amp, but the ratings say it'll push 2 10's.
You probably won't get much out of that amp with a 1230 watt subwoofer.
The subwoofer you are wanting to run is 300 RMS, so you'll get half the power you could be pulling. But it would do okay I guess. Nothing like what you could get with a different amp though. You need like a 1000 watt amp to get the most out of your sub. But "YES" you can use them together.

Amps on woofers are fine just won't hit


your probably making your amp run to low ohms if its a 2 channel amp bridged to one channel you can probably only run it at four ohms

Also seeing as your subs are 2ohm dvc you can't wire them individually to 2ohm and use each channel separately. So i'd recommend buying a 2ohm stable monoblock or running it at four ohms. a 1400 watt amp'll still pound at 4ohms and it'll extend your amp's life span

550x2 subs....SPL z2x-820 Amp


Hello,

The 230 watt amp is a little small for your subs. They'll work, but if you are looking for max SPL, you won't get it. To push those Audiobahn's to their potential pavement shaking max, I would recommend an amp in the range of 500-600 rms (2-channel bridged) or 1000 watts rms monoblock.

Hope this helps.

I need to know what kind of fuse my amp takes...


IT MAY MEAN THAT IT TAKES (2) 25 AMP FUSES
IF YOU HAVE THEM OUT SEE IF IT SAYS WHAT THEY ARE OR OPEN IT UP IT MAY SAY IT ON THE BOARD OR THE FUSE HOLDER OR LOOK @ THE SPECS ON THE AMP SEE WHAT THE TOTAL CURRENT IS YOU CAN ALWAYS START WITH A SMALLER AMPAGE LIKE 10 -20 AMP FUSE ALWAYS GO SMALLER

Trying to figure out what kind of amp i got amercian pro vs-3507?


The VS3507 Is a class D monoblock.
Your optimum wiring for this amplifier is a 2 Ohm load - so it produces its full potential power of 350W RMS.

To Achieve a 2 ohm load, the most common load is one of the following...
(1) Dual 4 Ohm Voicecoil Subwoofer Wired in Parallel.
(2) 4 Ohm Voicecoil Subwoofers wired in Parallel.
(1) Quad 2 Ohm Voicecoil Subwoofer wired in Parallel/Series.
(1) Single 2 Ohm voicecoil subwoofer.

Kicker cvr and ameican legacy 2000 watt monoblock amp. I just need to know if this would hit hard? n if der is anything i need so i wunt damage my 2006 malibu at the same time


The amp, i am not so familiar with, so do your homework...

You want to pay attention to sound quality specs such as signal to noise ratio (the higher the better, like around 100 ) and THD (total harmonic distortion, the lower the better, like between .1% and .001%) If your amp is putting out 2000 watts at a high distortion level such as 1%, you wont be too happy with the quality and you may blow your sub before ever approaching the full 2000 watts.

As fara as your car goes, a heavy duty capacitor would well placed between the battery and the amp, and upgrading the alternator may be considered. If not, you are looking at substantially shortening the life of both your battery and present alternator.
