Rockford Fosgate 100a2 Car Audio Amplifier Questions & Answers
Crackling in 1 channel
sounds like the D40D8 transistor the one that stands straight up on the board and not heatsunk! there are two of them. could have a cold solder joint there. have had a few of these problems from people doing hack repairs to them. they look like this http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=290297644906&ssPageName=STRK:MEWNX:IT
Its an old school amp,2 channels, but on
I have had a few amps with this sort of problem. first thing I do is take the cover off and look any black spots on the case or any black looking components, usually fairly obvious. or dry solders, where the solder isn't connecting the component properly. find the faulty party and fix it or take it out and get a replacement.
hope that helps
Ok so when i turn my bass up my kicker cut out
when u say the power cuts out.Do U mean the DC + power. Powers down on the amp. or does the amps protection kick on. and if it does. Is thier a flashing maybe orange/yelloowish light. If this is so. You might want to over look your connecting of your speakers. to see how it is wired.It might be crossed. -or-Is your amp mounted on something other than your vehicle. If it is U might want to remove it,and put it on another type of item that is not some kind of metal. I always use wood. Then i mount wood to A vehicle after the amp. U see A amp is not to be mounted directly to A vehicle. It grounds it out. when go to turn up your system it will cut off or sound like a pulse up and down kind of sound
Fosgate P250.2, No power at speaker outputs.
I presume you have the power light on as well? if not, check for twelve volts at the remote turn-on wire with a meter (you probably already did though). So, in conclusion if the power is on you should have speaker output. Check: the gain to see if it's not turned all the way down, your RCA Jacks might be bad or have a loose connection, your RCA output on your stereo isn't ouputting the sound properly (you might want to try a high-low converter and connect it up to you two rear speakers). Let me know what you find and we'll go from there. If you are still having problems and need more help, email me the details of what you tried and we will figure it out
One of my wires came out and it touched the amp
well first make sure your not pluging the power in the the ground and if that not the issue just toss it ....not worth getting fixed you could probably get a 1000 watt amp for the price to repair
I burned the amp what can i do?
I'm guessing your talking about the fuse. Replace it. Just get the same size fuse and put it in. Not really that hard just make sure it's the same number!
Amp was hooked up without fuse from battery to amp
Another failure must have occured, as the fuse would have blown, possibly limiting the damage, however something did fail to start the problem.
Nobody can give you an honest estimate without analyzing the damage.
A wild guess would be one-half the cost of the unit.
100a2 amp not getting power
get a strand of wire and jump it from the power to the remote if the amp does not turn on then take the amp and smash it over and over again because it is fried
Punch 100a2 problem ouch
Without the proper training in electronics , Nowbodys goping to be abl to explain to you the way to trouble shoot something without you knowing the lingo and also what the terms mean and do!. You also need to know how to use a multimeter, an ocilliscope,have load resistors to hook up to the amp . A good power supply . You also will need to know how to read a resistor as the resistor color code. And Know how to test capacitors as well as a solid state device. im sorry i cant help you but I wish it was that easy to do or I wouldnt have went to school all these years. Send the unit into the factory or to a repair shop as you could cause more damage if you short something out by accident. Good Luck
2 12 p3d212 2 ohm hooking up to a rockford
The P325.1 is relatively small to power a pair of P3's. You'll only get 325 watts RMS at 2 ohms (162.5 watts per sub). The P3's power range is from 100-500 watts, so they will work, but don't expect them to be really loud.
For best power, your subs should be wired with the voice coils in series and then the 2 subs paralleled to the amp resulting in a 2 ohm load.
Hope this helps.
