Question about JBL BP600.1 Car Audio Amplifier

No Output from amp, green LED on

The amp is receiving power, i tested it with my VOM. My RCA's are brand new, and i tested them. They are plugged in the right places. My Green LED is on. The Amp used to work then just stopped giving me any output. I tested my subs, and they are good too. Can i repair this?

Are you absolutely certain your subs are in good shape? have you put a meter on them and measured the ohms as you depress the cone [causing the cone to move up and down on the pole of the magnet? do the ohms stay constant? go up to infinity[ suggesting an open] or go to zero or close to zero [ suggestting a short] both of these conditions will result in a zero or a very limited output from your amplifier, while still showing a green status light, if or when a full short or open occurs on the subs, a fault led will become lit, and whet that means is that u have fried the outputs....do a bit more testing with your vom....and good luck or try another speaker for testing purposes...

Sounds like there is a problem with the amp. Try switching the inputs around for that output on the amp. If that does not help, Yes I would have to say that there is a problem with the amp output circuit.

Looking for manual for pioneer sw200 powered subwoofer

Most subwoofer have a left and right phono/RCA sockets. The amp should have a sub out phono/RCA plug. The sub should have come with a phono/RCA lead that will connect these - one plug to two plugs.
Apart from the mains plug that's all there is really. You may have to switch the sub socket on the amp on.

Or you can get one of the cables from places like below:

Adapter does not chanrge

make sure its plugged in correctly and the wall plug is plugged tightly. I had a Dell C840 when the
charger got power it had a green diode that lit up. You could test your power supply with a volt ohm
meter. if the VOM is not showing any power coming from the power supply (assuming you have the
VOM setup to match the power output of the power supply) then the power supply is probably bad.
If it works then it could be the computers connection or battery.

Got this amp from a friend and want to wire it up to my Sony head unit. The HU does have pre-out in RCA plugs. please help. I have tried it with: RED - stereo Amp Rem In YELLOW - 12V BLACK - -12V...

Senshin,
Red- 12 volts switched (ignition)
Yellow- 12 volts constant
Black- Ground
Blue/white stripe- remote amp turn on/ power antenna
If you have any orange wires there for the Illumination dimmer. (head unit dims when you turn the lights on). The white and gray are front speakers and purple and green are for the rear, solid being + and black striped being -. (gray and purple are right channels)Make sure that the RCA plugs go to the input side of the amp. I hope this helps, Ray

Hum sound when plug in. if i touch the input jack the hum sound disapear.

The best way to test your sound problem is to buy another pair of patch cables/RCA cables and try those, most likely you have a ground loop in the RCA cables, basically you are creating a ground when you touch it.
