Re: sony explode amp for my car
Try disconnecting everything but the power connections. If the protection light still comes on, then there's a problem in the amp. If it goes out, then there's a problem elsewhere. In that case, hook up one speaker cable at a time and power on. If the protection light comes on, then either that speaker is bad, or you've got too many speakers connected to that one amp output. Too many speakers connected together can cause an overload and trigger the protection circuitry, or worse, blow out something out.
Hope this helps, and please rate my advice.
Thank you, and good luck!!

2 tens are not handling the power load from your amp. The protect light means that the speakers have an overload safety device so you won't fry(literally) the speaker voice coils. I suggest adding more speakers(making sure the ohms are still correct) or more heavy duty higher power handling speakers. If you are unfamiliar with this process, best to utilize the services of a professional.
Sounds like you're overloading the amp. Which rockford subs are they exactly? I can find the specs and see if theyre just too much for the amp or you just have to hook em up to the amp different so the amp wont go into protect mode
you may have already blown the amp...if it is doing this with no speakers hooked up to it trace your power and negative line to ensure there are no breaks or kinks in the line...also verify you ohm loads and such and that the amplifier can handle what you are introducing to it( if in fact there are speakers hooked up to it)..as i said b4 however there is a good chance the amp is blown already
check your amp and speakers and make sure their both hooked up 4 ohm instead of 2 ohm because if you have 1 set of voice coils on your speakers they can only be hooked up four ohm and not bridged to your amp because if you keep trying this you will lock up your speakers if the speakers are only 4 ohm than just hook them up regular to each channel on your amp if your trying to brigde four ohm speakers to your amp it will keep going into protect or worst case scenario you will fry your speakers and you can check your ohm with a ohmmeter trust me my brother owns a stereo shop
Check the wiring between the sub and the amplifier. That's seems to be the only thing left that could cause a problem. If it's shorted to ground or pinched so the conductors are shorted together, it could cause the symptoms you listed.
Off hand, I believe there is nothing wrong with the setup, maybe just not 100% compatible. It's just that the Sony Amp's protection is doing its job (just too good) and the stock radio is likewise doing it's job (but not too good).
Just maybe, at poweron, the stock radio sends out a small burst output (maybe capacitor discharge) that we normally hear as a slight thump in the speakers which was when no Sony amp, ok. However, when you have added the amp, you also amplified the thump, which unfortunately the Sony protection reacts to.
You can off course let it be since you have figured out a way to make it work or you can try and install a delay on for the power amp or separate it's power on from the stock stereo. The idea is to turn on the stereo with the Sony off and after a second or less, a manual switch or a delay activated switch will turn on the Sony. The idea is to switch on the Sony after the thump has finished.
Good luck and hopes this gives you an idea. Pls post back how things turn up. Kind regards.
