How to repair jbl norhridge E series subwoofer

You can purchase repair on ebay - look for the auction under JBL VENUE SUB10

There is a guy on Ebay who repairs these - not sure but I don't think the board is available - you could check with Harmon - they own Infinity and JBL

The boards can be repaired - look for we repair and your model number on ebay -

The volume control pot can be replaced.

Any good quality audio shop or electronics repair shop should be able to fix this.

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.

Hiya, start by checking the power cable, then check the fuse in the unit on the pcb. If blown, replace and if it blows again then problem could be either Power supply or the amp outputs. If it doesnt blow, stays on but no sound, problem also likely to be output stage. You will need someone with experience to check outputs, etc and a meter though. Hope that helps a bit.
Best of luck

More likely to be bad amp module.

i have same speakers try these setting and tell me what you think put phase at 180 and put switch on lfe mode not normal for some reason my sub plays louder on these setting verse phase on 0 and lfe switch on normal i have power on subwoofer a little more than half also set croosover to 80hz you will never touch it again

Has nothing to do with the signal or source - it is a failure of the turn on circuit - I repair this amp - can help if you find my add here or I am located on ebay as well. Juust do a search for We Repair JBL and find the model :)

get a nice monster subwoofer cable and a Subwoofer PowerCenter™ SW 200 with Clean Power™ Stage 1 get it from like amazon and you'll definately see a difference and also put the sub in like a corner
