Keeps blowing fuses!!!

Check the FUSE to ensure that current is not cut off.

No - it is not 2 ohm mono stable

Thanks for using FixYa - a 4 THUMBS rating is appreciated for answering your FREE question.

Generally, if you are using the manufactures fuse rating you can use a slightly higher rating and it will resolve the blowing fuses. Fuses supply resistance, if there isn't enough resistance you'll fry the system board in the amplifier. But if you have 25 amp fuses installed, install 30 amp, if you have 30 install 35 amp, 35 install 40. Anything higher will damage the amp.

Hope this helps.

A rare chance, something may be internally wrong with the amp and shorting it out which will blow the fuse.

Use the incorrect wiring of subs to the amp, you'll blow fuses and damage the amp from it turning off consistently. The amp should be running at 2 ohm stereo stable or 4 ohm mono stable.

Very few amps are designed to run at 1 ohm or less. Not to mention the subs can't handle it.

I would strongly recommend that you get a 5 channel amp that puts out 75watts rms per channel that will deliver between 200-300 watts to the sub channel. I use planet audio amps myself and they run strong all day every day-maybe you could look at a planet audio vrx 600.5(5-channel) it throws 100w x4 and 200 or 300 to the subs depending on the resistance of the sub. Good luck

No, that'll use two channels to power one sub. First, is the gain turned up? There's a knob on the amp to turn it up. If the gain is already up, and if the amp is two-ohm stable, then wire the subs in parallel. I'm assuming the subs are each hooked up to their own individual channel. Swap the two negative wires at the amp, so sub 1 is hooked up to channel 1 positive and channel 2 negative, and vice versa for the other sub. That'll dramatically increase the output. Again, make sure the amp documentation says it is 2-ohm stable, or you'll damage your system.

sounds like the audio stage riving the channel has a short circuit on it.need to go through the amp stage

Hello sunshanel,

You did not say what you have the amp connected to and what the impedance load is. It is only stable at 4 ohms and if a lower impedance is connected, say 2 subs in parallel, it would try to produce more power when you turn it up and would most likely blow the fuse. 20 amp sounds right for the amp. The power rating of 800 watts per channel is peak power, not RMS, and many low-end manufacturers tend to state bigger numbers in the ratings.

Hope this helps.

Sorry wayne2953 but this amplifier isn't stable @ 1ohm loads. This amplifier would be better suited running a pair of 12's, 4 12" subs could run if configured correctly but the subs would be underpowered and probably not sound very good.

Features of Planet Audio VX3002:

• Max Power (2 Ohms) : 300W x 2
• RMS Power (4 Ohms) : 150W x 2
• Bridged Power (4 Ohms) : 600W x 1
• Signal-to-Noise Ratio : 102dB
• Frequency Response : 20Hz-20kHz
• Dimensions : 10-5/8"W x 2-7/16"H x 16"L

If the subs are dual 4 ohm voice coils and if your amp is good down to 1 ohm, your best bet is:

1. Connect the voice coils in parallel ("+"s together, "-"s together). This will make the impedance of each sub 2 ohms.
   
2. Connect the subs in parallel.
3. Bridge the amp to one channel.

This should max the amp out at 2400W, which means about 1200W per sub.

If your subs are single 4 ohm voice coils, do the same steps, but you'll only be able to load the amp to 2 ohms, which means about 600W per sub.

Also keep in mind that box size, type, and quality make a big difference in how subs sound.
