I have the Sony explode 1200 2/1 channel amp and 2 comp series lighting audio 10s 8ohm 900 watt max best way to hook up for loudest bass


You will have to wire subs together for a 4 ohm load. Then bridge amp (1 channel). Look on amp speaker outs to see what leads to use to bridge. Run positive and negative to one speaker then use a jumper wire from that positive and negative to the next speakers positive and negative

Older sony explod amp worked fine in car took out sat 4 monthes put in truck will no turn on ground power and remote ok indicator light does not come on


Put any bit of wire from the remote to the power of the amp. Then put a bit of wire to the + of your car batt and a bit of wire to the + terminal on your amp.....then put a bit of wire from the - of your car batt to the _ of your amp'....... The light should come on as you have bridged it, this showing it still works.....if not then its new amp time!!


Sometimes helps with 2 people doing this as one can hold the amp near the car batt' or if its just you place the amp on the engine, somewhere safe!!

It goes into protective mode even when there is no speakers or rca's hooked up to it.


It sounds like the output transistors maybe shorted or the power supply mosfets are shorted. Need to know what happend when amp quit working. Like was the volume up loud, or was you listening to it at a normal volume. Stuff like that. Alot of of the time in these Kenwood amps I have found that some zener diodes cause this problem by shorting out. Let me know what happend first before I start diagnosing anymore. Make sure all fuses are good and wiring to the amp. If interested I repair car amps for a living, cheaper than anyone or a another shop. I have over 15 years experience and repair amps everyday. Most of my out of stse customers are from fixya.com. Just send me a private message if interested, otherwise i'm here to help you the best I can and answer all your questions to the best of my knowledge.

I want to start repairing amps. how do i learn?


You will need to enroll into an electronics school to learn how to repair electronics on a component level.

How do I fix the problem so they work again.?


A 1000 WATT AMP HAS PROBABLY GONE INTO PROTECTION MODE BECAUSE YOU ARE TRYING TO RUN 1600 WATT SUBS COMBINED

Sony explode amp ''OVER CURRENT'' light on -no sound


just feed 240V through the RCA inputs and check if the amp power light comes on. if it does the the amp should have automatically been reconditioned.... you are now ready to rock n roll!!!

Sony xplod 1200 watt amp quit no kind of protect lite on please


short answer yes... Long answer... Amp Failure: There are many different ways that an amp can fail but the two most common failures are shorted output transistors and blown power supply transistors (< those are not blown). There are several types of protection circuits in amplifiers. The most common are over-current and thermal. The over-current protection is supposed to protect the output transistors. Sometimes it doesn't work well enough to prevent the failure of the output transistors but it will work well enough to shut the supply down before the power supply FETs are destroyed. If the amp remains in protect mode, goes into protect mode or blows the fuse as soon as the remote voltage is applied, shorted output transistors are almost certainly the cause. If the fuse protecting the amp is too large, if the protection circuit doesn't respond quickly enough or if the power supply is poorly designed, the power supply transistors may fail. If you see a lot of black soot on the power supply transistors (near the power transformer), the power supply transistors have failed. Soot on the board doesn't necessarily mean the transistors have failed. Sometimes, technicians don't clean up the mess from a previous failure. Transistor Failure/Checking Transistors: In general, when a transistor fails, it will either short (common for output AND power supply transistors) or open (common for power supply transistors). Transistors act like valves. They control the current flowing through a circuit. A shorted transistor acts like a valve that's stuck open (passing too much current). In the case of an output transistor, the shorted transistors tries to deliver the full rail voltage to the speaker output terminal. If you've ever seen a damaged amp that pushed or pulled the speaker cone to its limits when the amp powered up (common on some Rockford amplifiers), that was almost certainly due to a shorted output transistor. When checking transistors, you most commonly look for shorted connections inside the transistor. You do this by using a multimeter to look for low resistance connections between the transistor's terminals. Note: I used the terms short and open on the previous paragraph. A short (short circuit) is a path through which current flows that should not be there. An open (open circuit) is a break in the circuit. It is most likely the power supply that has taken a ****.

D7401 doesnt work


There is no fuse on this amp. It requires EXTERNAL fusing, as it is a PRO amp.
There are diagnostic LED's on the board if you look inside. They may point you to a problem, but the odds are the amp is shutting down because it is detecting a problem. You need to take it to a repair shop for an good tech to fix. Unless you are VERY into electronics, and very knowledgeable about the operation and repair of car amps, I would not attempt to repair it yourself. It is a very nice, expensive, high power old school amp. The power wiring needs to be sufficient as well. This amp will draw ALOT of current at full power. (80 amps or so I think) there's manuals for it floating around the net with the exact specs needed for the external fuse).
