Rockford Fosgate Power 1000 amplifier. (25 to life) When I turn it on there is almost no sound coming from speakers. I have to turn up the volume almost to max to hear something. But only very high...


turn or flip the LPF and sub sonic buttons to see if they will help.
there are other buttons called gain that you may have to turn to bring up the volume.
its very likely your eq buttons that you have to mess with to get it right. post up pics if you can.

I have to hook up 4 amps in my car. 4 channel 700 watt ken wood, 2 channel 800 watt Sony, 4 channel 740 watt Jensen ,and a 2 channel Rockford fosgate. Which is best way to hook them up so I'm not ki


Pace posted on Saturday, March 05, 2005 - 01:08 GMT Your subs are dual 4 ohm voice coils so if you want to bridge your 2 channel amplifier to your two subs then wire them parallel, meaning the + to + and - to - ( Do this to both subwoofers), Then run a wire from one positive and one negative on each sub and bring the two positives together and the two negatives together and hook both positives to the far positive connection on your amp and connect both negatives to the other negative on your amp,

This will create a 4 ohm load on your amp.

Although if it's a two channel and you have two subs it's usually pointless to bridge them because if you use one channel per subwoofer its going to be the same as if both subs were bridged. example) 800 watts x 1 bridged power of your amplifie (4 ohms) is the same power as 400 watts x 2 at 2 ohms.

Amp powers up. the right channel works fine left not at all


If you didn't find any burned parts that would mean one of the buffer amplifiers before the power amp could have died. They could either be transistor based or opamp based. They are fairly low power so they will not explode like the output transistors like to do. Contact rockford, they should be able to send you a schematic. Let me know I will try to help you through it.

Connect rockford fosgate amplifier & speaker together


Assuming your P3 has a single voice coil (it will have only one place to plug your wires into) you will be running this in a bridged mode. You will take the left (+) coming off the amp and plug it into the (+) on the P3. Then take the right (+) from the amp and plug it into the (-) on the P3. This will make your amp push 500 watts to your sub. Now on the amp make sure your adjustments are as follows: Signal input switch is set to unbalanced for RCA input. Left Phase switch is set to 0. Right phase switch is set to 180. your X-card should be set to low pass. And adjust the gain for both R and L equally so it has equal power from both channels.

Mackie CR1604 has a consistent click at hi gain


Without hearing the noise or seeing it on a scope, I can't say for sure, but this type of noise can come from a number of sources. If there is a high signal level on one bus, you could be getting some cross-talk from that channel onto the channel with the higher gain setting. Try to track this down a bit by experimentation. For example, do you hear this with NO connections at all, but with the gain turned up on one channel?

Please try a few things to narrow this down a bit and I'll try to provide you with some options.

Thanks,
Dan

I have a rockford fosgate p250.2 amp hooked up to two 12' subs but the amp is not powering on... instead the protect light is on and im not sure if its because its so cold outside... please help and thank...


Remove the load from the amplifier (subs) and the RCAs
Retry.
If the light stays on, there are internal problems with the amplifier, and it needs to be serviced.
If the amplifier works normally, attach the RCA's and power on again.
If it remains on, connect one sub, and then the other.
Your amplifier is a 2 channel amplifier rated at
60 Watt - 4 Ohm - 2 channel(s)
125 Watt - 2 Ohm - 2 channel(s)
250 Watt - 4 Ohm - 1 channel(s)
Your amplifier is not rated for a 2 ohm mono load.
If you have Single voicecoil subs wired in parallel, you have a 2 ohm mono load - your amplifier will eventually fail.

ONE CHANNEL NOT WORKING


Please don't take offense, but some tips on submitting problems on Fixya:
  • Resist the urge to use all capital letters. Reserve them for frustrating yells :).
  • Use a period or two. It's very hard to read without them.
The easier to read, the better responses you'll get!
Anyway, back to the issue at hand.....

Definitely get a handle on the gain adjustment. Both channels should start with a gain at the 50% point. Also, you can try bridging the amp ("+" speaker outputs tied together, "-" speaker outputs tied together) and run the full 800W into the single 10" sub, but that is going to depend on what your sub is rated to handle.

The only other thing I can recommend is call around to a couple stereo shops and see if anyone can test the amp for output power. That'll verify whether there's really a problem on the one channel.
