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.

Hi, I was trying to replace my subs and during the process, the positive wire touched the negative wire and my amp turned off. I have the Punch 801s 2400 watt amp. Is there a way to reset it? I'm assuming...


Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Your amp is clipping. A thumbs up would be greatly appreciated if this answer is helpful to you. GOD BLESS YOU.

Why do i need to open my gain up to 3/4 to full turn inoder to achieve a loud bass?Im using punch 2400 amp and 2 12" kicker.


the amp may not be powerful or your setting on the cd player is not right try adjusting the cd player. turning the gain all the way up will damage your subs even go above halfway

How do I hook up one sub to my rockford fosgate p3001 amp


Hey i have looked over many rockford manuals,(i own a 300.1 my buddy owns a 325.1) and for there mono(.1) amps there hooked together on the inside so channel A+ and B + are cencted on the inside the amp. So you ither hook one 2ohm sub to channel A or you can hook 1 4ohm subs to channel A and 1 4ohm sub to channel B. There 2ohm stable so any lower will eventualy burn the amp out.

On the 801s there are 2 power holes and two ground wire holes why...


basically it is so you can get better power and ground connections.

Will my car handle a rockford fosgat 801s power load?


Hello dreww1005,

If your alternator and battery are in good condition, you probably don't need a capacitor. At maximum output, the 801S will need to draw a little over 30 amps at 12.8V. The specifications call for 8-gauge power and ground wiring and a 40A primary fuse. The Vibe's electrical system should be able to handle it OK.

Hope this helps.

Amp or something cutting out.


Power caps store power from the battery and they feed constant power to the amp so you dont get no drainage! this could be one reason..

have you bridged both subs and wat gauge wire are you using.

these amps can only handle one bridged sub at 4ohms and this amp is recommended that u use 8gauge or higher. if your running to subs i normally reccomend using 4 gauge power wire as you get more rms power feed to the amp

you can get a power cap or anyother accersory cheap online at my suppliers.. caraudiosecurity << click to enter >> hope this helps and please rate me :)

Is it enough to power to 12 volge=ahagen 12oowatss dual 4 ohms


your Volfenhag 12" subs are rated at 1200 watts they are only 600 watts rms and the Rockford punch p4004 is only 200 watts rms so the answer is yes it will work but if you get a amplifier that pushes out 500 - 600 watts rms you will love the sound from subs
there is nothing wrong with the Rockford amp it just wont pound out the bass as hard but the good news is you will never blow the subs with it
when buying amps or subs make sure to look at rms rating that is the true power they actually have ie. (sub box says 1200 watt you think powerful but if you divide it in 1/2 you actually get 600 watts rms) don't get me wrong that's a nice rating. for a sub but you will want to match that number with the amps rms rating or lower. The RMS is what makes the car pound the higher the RMS the better
hope this helps

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.

Will not power


are u sure you didn't blow a fuse? check the fuses to make sure you did not blow one because the amp will not work in that case. make sure you are not over working your amp as well because it seems like that amp is not big enough to power all four of those subs. usually 4 channel amps are used to power speakers not subs. what is the rms on your subs and amp? i could better tell whether your amp is big enough. thanks hoped this helped
