I had a rat that ended up inside my sub and one day i noticed a smell so i hurried and shut my stereo off and there he was.. he chewed on wires which fried my board.. so now im in need of a new circuit board

It sounds like you have been experiencing issues with your Formula F-12 amplifier, and the fuse continues to blow even when the amplifier is removed from the sub box. The fact that the fuse blew when you gently pushed on three small resistors suggests that there may be a problem with these components.
Resistors are passive electronic components that resist the flow of electrical current and are commonly used in amplifiers and other electronic circuits to control the flow of current. If the connections inside the resistors are weak or damaged, it could cause an issue with the circuit and potentially lead to the fuse blowing.
Replacing the resistors may help to fix the issue, but it's important to make sure that you use the correct type of resistor for your amplifier. You should refer to the manual or a diagram of the circuit to determine the correct values and ratings for the resistors.
It's also a good idea to check for any other signs of damage or issues on the circuit board, such as burnt or corroded components, loose connections, or physical damage. If you are not comfortable working with electronic circuits, it may be best to seek the help of a professional repair technician.
HOOKING UP A BATTERY BACKWARDS CAN CAUSE SEVERE DAMAGE. THE SMELL IS MOST LIKELY ONE OF THE CONTROL BOARDS THAT SHORTED. BURNED CIRCUIT BOARDS REQUIRE REPLACEMENT
replace ignitor assemblyand set a trap for the rodent, penutbutter on a snap trap works best,no posion and it wont crawl inside the walls to die and smell up the joint PSthe bigger the rat the bigger the trap
you should not use the unit if it smell like a electrical problems. it could be your indoor circuit board you could take it out if you realy wanted to make sure its unpluged and see if there is any loose cables check if the fan free spins and does not feel stiff
9check connections inside sub enclosure(assuming they are in one)mine loosen up after running them hard for months on end.they act the same way yours are.
the voice coils are probably fried. you may want to check your amps to see if they are putting out dc voltage. you may be abel to find a place that can fix the subs. otherwise you will need to replace them.
Hi Bill,
You will not like this repair at all. It is cheap and easy but usually really gross. So hold your nose and read on.
This time of year we have little visitors in our garages that like to find a warm place to cuddle up. They will crawl into the back of your freezer and find your warm compressor and start looking for places to build a house. While walking around they will eventually walk directly into the condensor fan and and usually they will not die, they will just be stuck in the fan blades. The heat that begins to build up will slowly cook the little critter and you will get a foul smell for a couple of days. Then you will notice the freezer has stopped cooling well. To repair simply remove the rat from the condensor fan and you got it fixed. In some cases the fan can burn out from the jam so you may need to replace it. I always hate to do this job, it is easy but who likes to handle a cooked rat??? Grossss.. Please dont forget to rate me and try to have a nice day.

The amps do have issues that is for sure - That is where I step in - I can repair your amp and make it so it won't burn up (catch on fire) again. When the amp goes it burns a hole in the board - but it can be repaired. I have done several hundred and all customers are happy :) ... Look for my add here and also on ebay
I had this same exact problem when my last older Kenwood Marine stereo cooked itself while I had it up loud for a few weekends on the lake. (smelled like it had burned inside). I went out and bought a new Kenwood KMR-550u stereo deck. (I do not have an additional amp). I hooked it up to the exact connections where my older Kenwood stereo unit had been hooked up, as I never had a problem with this for the past three years until it failed after smelling of burning elelectrical. I had chalked the problem up to heavy rain we had one day. Every time I turned up the volume, sometimes up to 27 out of 35 possible, or 29, or 32, the stereo would suddenly shut off as if I had turned it off. After a few seconds the stereo would come back on, but unless I was quick enough to turn down the volume it would do it again right away. Of course on a boat, we were beached in a cove and the engine was not running when I encountered this. I searched the internet finding hundreds of similar complaints and several dozen theories of all types, but only a couple that pointed me towards the power (voltage) idea as the problem. I put a volt meter on the positive & negative wires powering the stereo. I watched as I gradually turned up the volume, the voltage on the power wire gradually decreased from 12.5 volts, down into the 11 range, and as it hit 10.9 or 10.8 volts it shut off typically around a volume of 32. The red power wire in my boat that never seemed to have an issue with my old stereo until it fried was determined to actually be inadequate for the power flow for the new Kenwood, and probably was the culprit of my failed older unit. I offer this sound advice: Run a new pair of positive & negative wires directly from the battery (with an appropriate fuse of course (the deck has a 10 amp fuse in it's back so I would use that at the battery) to the stereo. Check the voltage as you turn the volume up into the high 20's and low 30's to ensure you are still getting voltage in the mid to high 11-12 volt range. The stereo is designed to require a minimum of 10.8 volts to operate, and when it drops below that it protects itself and shuts down.
