I went to use my car stereo and found out that there was no power to the amp. So I looked at the fuse between the car battery and the amp,, yes it was blown. I replaced with a new fuse(30 amp) and now the light that is normally green on the amp is RED. I checked the two 30amp fuses on the amp itself and there fine. I checked the ground wire and cleaned it up, its fine. So what I think I need to do is RESET the amp,, and I don't no how, does anyone now how to reset the 800w sony explod amp?? It has power because the light is red,, all fuses are fine.....I'm stumped. Thanks for the assistance.

Re: sony explod 800W amp
If the amp is in protect mode, it probably has shorted output transistors. To eliminate other possible problems, do the following.
With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.
If the voltage remains near or above 12v, disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp almost certainly has shorted output transistors and will need to be repaired.

Check the connection to the battery. Be sure it is making a good contact. Then check the voltage from ground to just before fuse and just after fuse making sure that you are having the correct voltage.
Walmart, K Mart, Auto shops, car stereo shops would be a great place to start to search for fuses. Make sure you take out the old one from the amp, and I would also take out the fuse from the battery compartment as well. Do not buy bigger rated fuses, make sure they match the ones from your amp!
I have a similar setup & I just run the second amp straight off the other amp by running positive & remote wires directly from 1 amps positive & remote inputs to the others amps inputs. But my head unit has RCA inputs, (sub in & front & rear inputs) so from my 4 channel amp I run 2 6 inch alpine S's to the front to the front RCA inputs of the head unit, & 2 Pioneer 440w 6x9 inch speakers to the rear inputs. & my 800w 12 inch sub from my 2 channel amp to the sub woofer inputs on the head unit. Has blown my eardrums for nearly 12 months now great stuff!
Hope this has helped
Does the amp power up? Did you knock the fuse loose with a deer hoof? Sorry couldn't resist that. Check all of your wiring with an ohm meter especially your speaker cables. Check for DV voltage at the power input to the amp and also the remote turn on. If you get voltage there try turning the amp on and measuring the AC output voltage of your amp from plus to minus. (crank the volume up) That will also tell you if your amp is functioning. Verify signal to the amp. If you have a portable stereo with aux inputs drag it out to your car and plug your RCA into it. If you get sound to your portable stereo you have signal. You can't reliably measure the AC voltage with a meter because it is so low, if you had a scope that would work. Test your subs on your home stereo, (verify impedance first). These are just some ways to divide and conquer good luck man!
hey dennis if you have a standard car amplifier all you need to do is run a wire from the battery post straight from the battery to amp batt+ post, then negative side can also be run straight from battery negative, than the remote post on your amp. you can either utilize the power antenae circuit coming out of the stereo unit or an ignition power from your ignition power fuse box so you don't draw battery power when key is off, please reply back if your stereo unit has rca output and does your amp. have rca connection(rca connections are red and white audio cable style connection).
have you checked the fuses on the amp if so you can try to check for power of the amp straight from the battery by connecting the remote wire and power or battery wires together putting them on the positive terminal on your battery and the ground or earth wire on the negative terminal on your battery if there is no faults it should light up
Supplies needed: - 8 Gauge power wire (long enough to run from your battery to the amp placement) WITH an inline fuse!! - Depending on your stereo (if it has amp pre-outs or not) you will either need RCA cables (long enough to reach your amp from your stereo) OR a Line-Out converter AND RCA cables. - The power lead that connects to your "REMOTE" line on your stereo (long enough to reach from amp to stereo - usually blue) - A good ground wire ( long enough to reach a metal part of your car from the amp)
====================================================================== STEP 1: Find a spot to run the power wire from your battery - through your firewall and into your car - and then to your amp. (DO NOT CONNECT IT TO ANYTHING YET) STEP 2: Remove your car stereo and look to see if you have PRE-AMP outs (RCA connectors for an amp on the rear of the unit) A- if you do, GREAT.. proceed to step 3 B- if you don't.. you will need to get a LINE-OUT CONVERTER - what this does is converts the higher signals from your standard wires on your radio, to RCA style wires to connect to your amp. B2- you will also want to buy a wiring harness kit for your stereo, unless you want to hack away at your factory wires.. (not recommended) - connect the harness kit to your factory wire harness, wire in your leads for the output converter, and run the other end to your stereo.* *you will need to know which wires run to the speakers you plan to power with the amplifier B3 - once the converter is properly connected - proceed to step 3 STEP 3: Plug the RCA cables into the stereo or converter, and run them properly from behind your radio to the amp but DO NOT CONNECT THEM YET. STEP 4: Connect the REMOTE wire from your stereo to the same wire for your amp . (this enables the amp to turn on/off with your radio.. otherwise.. you will have alot of dead batteries) STEP 5: re-install your stereo into the car. STEP 6: Connect the RCA speakers into the INPUTS on your amp STEP 7: Connect the REMOTE wire to your amp. STEP 8: Connect the speaker wire from the OUTPUTS on your amp to the speakers you wish to power STEP 9: Connect the POWER CABLE to the amp PROPERLY STEP 10: Connect the GROUND CABLE to a metal part of your car (sheet metal, not just a bolt) STEP 11: Connect the POWER CABLE to the battery cable STEP 12: Re-connect your Battery STEP 13: Start your car, and test your radio.
If you have any issues from here.. you need to re-check all of your connections.
the wire from your battery is blowing fuses? and you are using 20-30 A fuses? mine has a 100A fuse..look into getting new wire plus my wire is 4 gauge.., 1600 watts is too powerful for a 12 g wire and a 30 A fuse
