Re: my amp is only pushing the left.

Swap the RCA inputs to see if the dead channel follows the RCA input.

How do i get this amp to workin an Oldsmobile Intrigue with a factory radio?

you need a hi-lo adapter and that hooks up to the right or left rear speaker then the remote wire needs to go behind the deck to the ignition wire. if the system is pre amp then you have to bypass the amp system

lets do some diagnosis.. if it's possible, try hooking another known good sub up to the amp and see if that works. if it doesnt, it's an issue with your amp. if it does work though, it's an issue with your sub. or the wiring. if it's a dual voice coil sub, make sure you've got both positives hooked up to positive from the amp, and both negatives hooked up to negative from the amp. if you've accidently got positive from the amp going to positive of one voice coil then to the negative of the other, and the negative from the amp going to the negative of one voice coil then to the positive of the other, the voice coils will be pushing against eachother cancelling eachother's movements out. and this will fry the sub. OR the sub is already fried.

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.

I have a nitro 1200 watt amp earlier today it was workin with no problems we parked then came back in the car 3 hours later and it wasnt workin wont come on or anything just red light which is protecting...

Check your speaker wires, make sure everythings connected right with no short circuits, and check all of the fuses in the amp, and make sure none of them are blown. If all this checks out just check the battery wire, grnd, and remote wires. It has to be a wiring issue unless you busted your amp, but if was working when you tuned it off it should be alright... hop this helps...

No sound and current read 0 amps reads 0 it is installed correctly it was workin before then quit the volt indicater started blinkin now the light is constant but no sound the volts reads 12.1

Check the fuse on the unit first, if fuse is good and you have power to the am you may have fried it. This is common when the speaker load is not adhered to prperly. Make sure your speakers are connected properly (2/4/6/8 ohms) and not exceeding the limits of the amp, this fries them 99% of this time.

Hooking up system using HI-INPUT amp wires.

This may sound dumb, but are there any other inputs left on the amp? Most amps that i have worked with have a special set of inputs for high input. (by high input you mean speaker level right?) If those exist the obvious answer is to use those. They should be labeled, so just hook them up according to them. You may need a special adapter from the amp manufacturer. If you dont have any high level inputs or any not broken inputs left you have two options. You can either A: junk the amp or B: open it up and solder new connectors back on. (it sounds harder than it really is. There are four large pieces of metal to solder onto the board for a set of inputs)

Another question for zzedly about the speakers cutting out

So, as I see it, your system is hooked up like so:
  • Ch1 = Left speakers, front and back
  • Ch2 = Right speakers, front and back
  • Ch3 = One sub
  • Ch4 = Other sub
One thing you can try is swapping channels. Swap Ch1 with Ch3 and Ch2 with Ch4. Then see if the issue still occurs on the door speakers or do the subs suddenly cut out at loud volume. If the subs start cutting out, that means the issue is with Ch1 and Ch2. If you haven't already, check the RCA connections to Ch1 and Ch2 as well as the gain for all channels. If the gain isn't already set to about 50%, put it there.
