I bought one of these and it knock's the wattage down to almost zero? Speaker's are crackling.. Any ideas? Thanks.

We needed to upgrade our receiver to include outdoor speakers. Once we did that it works beautifully

Are you sure that you've installed the unit correctly? Inputs connected to inputs, and outputs connected to outputs? Additionally, have you verified that the impedance switches are set correctly? Lastly, have you removed the volume control, bridges the speaker wires, to eliminate a fault in the cables or speakers? If you've tried all this, and still experience trouble, I'd say it's possible that you may have a faulty unit..

U can not put to much power to this subwoofer ..... And if ypu do and it sound like it want s to blow... Just turn it down n back up a min later.....and it cant not blow .... And later it s brand new all over again

Try changing the ground cable to a thicker one nd ground it to the chasis. Nd chek ur speaker wires. In and out the box.

Are you saying the fuse blows? If so be sure your speakers total resistance is not lower than the rated value of the amp.

the same thing has been happening to me. I think it may have something to do with the slight spark and pop that occured when I attempted to connect my speaker wire while the unit was on.

Sounds like it'll be slightly under-powered. It's always better (IMO) to overpower speakers to avoid blowing them at odd frequencies and high volumes. Power is exponentially more important than quality of speakers. Cheap speakers will sound great with an awesome power source but great speakers won't live up to their potential with inadequate or overrated ( cheap) power/amplifiers. My suggestion is overpowering your speakers about 15-20% more than the speakers are rated for. Won't matter if you don't "work" your speakers hard but under powering effects rebound of the speaker cone and can tear them apart. I believe these speakers are rated for either 125w or 150w. I matched mine up perfectly and wish I would have gotten a bigger amplifier, although they sound great but begin to struggle at very high volumes. It'll be fine if you don't abuse your speakers though.

Currently, I am experiencing this same problem, and contacted JBL technical support team. They said the unit is defective and that they would send a replacement unit, provided that I follow the given instructions, which was not problematic to me. Simply put, this is a common problem, and JBL is willing to right a wrong.

In the past I have had to deal with mismatched speakers of high wattage. I used a matching impedance amplifier.. Unacceptable here, So a possible solution could be, hook it up as normal. If it works to your satisfaction all is well. If not go to Radio Shack and buy a 4 ohm-1 watt resistor and connect it in series. Depending on speaker design, that could bring out the power to an acceptable level. If that fails... well ... its filter stuff and the cost is probably unacceptable.

I have not experienced any problem as described with my speakers. Sorry I can't be of more help.

As long as your speakers are 8 ohms there is no reason for the amp to overheat. I would say that the amp was defective.

ask the seller. maybe they'll replace the duds. Weird, I've never had even one as far as I know.

Make sure the connector you are attaching to the box itself is in the right position.......it is very tricky. Sometimes I think I have it right and it is not. The shape of it is not the best to distinguish the top from the bottom. Other than that possibility, it could be the indicator light is just simply not working. You may need to send it back for a replacement. And DO THAT.....I absolutely love mine. It is a GREAT little speaker. :)

Speaker needs same ratings or it might damage unit or speaker . 4 ohm 8 ohm or 16 ohm and wattage ratings need to be within ratings for both , polarity also should be checked

It is doubtful that this problem can be fixed by the user. If it is still under warrantee, contact the manufacturer. An alternative is to measure the output with a VOM.

I don't know how did you plug in the speakers? It has 7 separate amps! Just be careful about its high-current capability, thats causing the over heating!

check the wire connection. I have to wiggle mine around to stop static, loss of sound in one ear, and clicking. I always press my connector in firmly to be sure. If that doesn't work, I'd suggest trying new speakers.

Sounds like it's a dud. I have a lot of these and, fortunately, have never had a problem. I'd contact the seller and ask them to send a replacement. Good luck.
