Question about Rockford Fosgate Punch® 450.2 Car Audio Amplifier

1 Answer

I have a 450.2 Watt Punch Amplifier by Roxford Fosgate that powers a single JL 12" or 13" inch subwoofer, the amplifier used to show the protect, thermal, and power as being on, however during my last stages of use only the power light was on and the protect, and thermal lights were off. The installer placed the amplifier below my passenger seat, and whenever someone adjusts the seat back it turns the power light back on and my bass is restored temporarily, can anyone help give me some advice as to a more longer term solution, what the potential problem could be, and approximately how much it would cost to fix it, any help would be appreciated.

I would have to say you probably have a bad connection on one of the amplifiers wires. (My guess would be the ground.) If you can see the wires on the amp check to make sure they are secure. (Make sure you disconnect the ground from your battery before playing with the wires to make sure nothing gets shorted out or you could even fry something electrical) If all the wires are secured to the amp, if all wires are secure then you can reconnect the battery. The next thing I would do would be to check where the amp is grounded to the car's body. I would have the radio on and wiggle the ground wire (the part attached to the car, not the amp) to see if any lights come on.

Also if you take it in to have someone else look at it, it shouldn't cost a whole lot, just tell them you believe you have a loose wire somewhere.

If you had this installed recently, I would recommend taking it back to where you had it installed and ask if they can look at it for you, and if it was their mistake they should fix it for free. You paid for their services there should be some kind of warrenty on their work.

Received a RF P2002 for Xmas want to install in my PU to power 12 in woofer I can figure out the input do I just connect the woofer to the bridged + and - or is there something I need to do to get thi


this amplifier is a 2 channel 50watts rms per channel and would not really be powerful enough to drive a subwoofer of any substance for car use, however , bridging it would give you 200watt rms into 4 OHMS but your subwoofer would have to be a single 4 OHM voice coil. Best you use this amplifier to drive a pair of speakers.
Hope this helps. let me know if I can further assist you

I need instructions connecting my car subwoofers


Bridging your amplifier @ 4 ohm will yield the most power.... with the subwoofers you have.
You must wire them in Parallel.
Positive on both subwoofers to + on amplifier.
Negative on both subwoofers to - on amplifier.
The lowest impedence possible with 8 ohm woofers is 4 ohms.

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.

Rockford fosgate punch 700s gets very hot


Disconnect the speaker wires from speaker terminals on the amp and turn the amp on (turn the head unit on). Set the volume to zero on the head unit.

Does the amp get hot?

If it does, either the bias is set to high or the amp has other problems. If it does not, you may have the speakers wired to the wrong ohm load.

MY AMPLIFIER


HI SOUFBOY , Theres a few things you need to check , First make sure that your amplifier is getting an audio signal form your head unit,Check all the wires for breaks in the amplifier input, secondly make sure that your 12 inch woofers are still connected to the amp check all the wires . Thirdly check your woofers are they blown ? . The best way of grounding your amp is by scrapping all the paint on a spot on the car body inside the trunk or wherever you have it and making sure the ground wire is securely screwed onto the car body on that spot ..
