please see attached pic it has been marked up to show where the loose resistor went, and they both look burnt. 10 ohm 2 watt.

also you will see another resistor has been circled its also desoldered and likely burnt, and a small arrow points to it sister for the other channel under the bar and it also is likely damaged. These are the zobel output filters and they overheat when a amp is clipped badly and or it has some out of bandwidth output on the speaker terminals.

These device die due to abuse of the amp, and are side effects of the amps failure mode so fixing these items will not completely fix the amp. they are just symptoms of a greater issue lurking elsewhere in the amp channels.

Perry I am borrowing your links hope its ok, and thanks


Superjoey01 please click on any of these links below except for the computer link for some excellent reading that you need to do before you proceed with any repair work on your amps.
Links >> Basic Car Audio Amp Repair --- Basic Car Audio Electronics --- Basic Transistor Testing --- Basic Switching Power Supply Design --- Basic Computer Skills << Links


Perry's web site will answer many of your typical questions your asking now, and it will save loads of forum thread space if you study up a bit..... His training site will give you the head start you are looking for and its free and well designed so that you can take things at your own speed. Please brief yourself for this service work as its going to get a lot deeper and you really need to know the info Perry has put together for you.
I am detecting from your questions that your not ready to do this sort of repair yet. With some small training from Perry's site you will be ready to undertake this repair. I send you there to save both of us bunches of time and effort. I can guide you quickly if you have some rudimentary understanding level of what your working with.
I have done enough of these to guide a blind man, but the blind man needs to know what he is fumbling around with. Perry's site is your best bet to garner the little details you need to start this job....

I like many others here want to help you but you must help yourself also. And the info on Perry's web site will brace you some for whats next to come. Repairing electronics is not as simple as just replacing the visually bad components and you really need to know how to use the tools of the trade and some of the ins and outs before you run head long into this project. Your learning curve is the bottle neck to getting this done quickly. Perry's web site will smooth a lot of this out and help you vastly to achieve the results your looking for in this project.

I am not trying to be mean spirited towards you in any way. I am trying to guide you correctly to the help you need in the sequence you need it so you can be successful with your efforts. So please don't take any of my guidance harshly as its the best way for you to go, and we all want the best for you and your project here on the DIY...

Were here on the DIY not going anywhere so we will all be here after you have done some study up. Take a break, read some and then decide if this is for you or not and we will all be here when you have a better idea of what your into...

Perry's web site will show you how to ohm meter out all the power devices on the sides of the amp. I would start with that just to see if anything is shorted out . Let me know what you find...
