SOURCE: JBL SUB ACR10 SUBWOOFER

I would suggest to check the rectifiers first, very unlikely that the capacitors became shorted.

How do you bi-pass a jbl subwoofer sb 400 to a sony str- dn850


If they both run the same ohms, why would you want to by-pass it? Just disconnect the sb 400 altogether and wire straight into the dn850. If the 850 is amplified (plugs into a wall outlet), however, you may wind up with some distortion, especially if the signal coming out of your receiver also is hot (amplified.)

JBL PB10 subwoofer sounds distorted and lights on the front flash


More likely to be the Class D power amp module, but you should look through the service manual to make sure all the parts are installed correctly. My PB10 AMP module went out and you cannot get one anymore.

JBL PB10 has lost power even though still plugged into wall, any suggestions?


Do you mean like the subs power lights dimming when playing it at volumes it once had no problem playing, or loss in sound, distortion?

Finding the best amplifier


Hello sharky75,

That 1600 watt peak power figure for your subwoofer can't tell you what amp you need. You need to know the maximum RMS power the sub can handle. And you need to know the impedance (ohms) of the voice coil(s). JBL GT5 series subs have an RMS rating of 275 watts. The GTO series handles 300 watts. The Power series handles 400 watts. The GTi series handles 700 watts. Some are single voice coil, so the impedance is fixed. Others are dual voice coil allowing you to wire them for different impedance loads.

For maximum performance your amp should be able to provide at or near the same number of watts RMS into the lowest impedance at which the sub can be configured. For example, if your sub is the Power Series Model number P1224, it has dual 4ohm voice coils and can be wired to present either a 2ohm load (parallel) or an 8ohm load (series). You want to wire the voice coils in parallel for the 2ohm load and select an amp that outputs up to 400 watts RMS into 2ohms. The Orion Cobalt CO8001 is just such an amp. If you have one of the GTi Series subs, a better amp would be the JVC Arsenal KS-AR75 which outputs 700 watts into 2ohms.

Hope this helps.

There is actually some good news.  I had this problem with my PB10s (1 have 2 PB10s and 2 PB12s) It is one of 2 things, the first is that it could be a capacitor and resister combination on the amplifier board (which was the fix for our PB10 with the same problem), or 2nd, the AMP IC, which is not available for the PB12. hmmm
