2009 vlx no bass in speakers and nothing from the sub..

[jonwindsor]

Hi All,

2009 vlx and i can't get any bass out of my system.  I have the stock RF HU and the screen doesn't work and hasn't worked since I've owned the boat.  Could the bass of gotten turned off in a setting?  Could it be the JBL "black box"?  I've traced a ton of wires and checked a ton of connections.   I also have the WS 420BT.  It's working but but still no bass and nothing from the sub.  Its almost like all my speakers sound flat.  Any way I can completely bypass the stock HU and just use the 420BT?  I also have a inline Bluetooth module for my source of music. All three amps- one for the tower speakers, 1 for the interior speakers and one for the sub all have power so that's not the issue.  This all happen when i was riding and my buddy was driving.  Did have kids in the boat so not sure if a button or two could of gotten pushed or not. Any other ideas? 

Thanks!

Could be why the screen is not working. I do not think the one screen brand is compatible with the others black box.

Sure! As long as you are content with blue tooth or hard wire AUX for your music source. With the screen out on the factory system, how are you using the black box currently? Is it just stock on one source mode?

Where is this plugged into the system audio wise?

The Bluetooth is wired right into the AUX on the 420..

After more investigation looks like I’m not even using the black box but it’s all running through the 420 and amps.

Ok, good, this narrows it down a little. We dont actually want bass from the full range speakers. Mid-bass ranged, yes. Bass we want from the woofer. 

As to the lack of desired sound quality from the speakers; Check your phone's EQ setting. I prefer off or flat. Center the EQ frequency dials. Next, you would need to investigate the amp setting. Woofer amp powered up? Power light on and in normal or protect mode? No light or protect mode, check voltage at cables. Swap the in-boats or tower amp RCA with the woofer RCA outputs at the back of the EQ and see if you get some woofer output. Just make sure both the master and zone volume are turned up. This to, can be amp setting.

Do you have the RF remote bass knob adjustment? Might of been turned down or off. Silver box below the key.

Just started focusing on the sub amp and the sub wires.  Took your guys advice and just assumed the speakers were not tuned well.  I took the sub off the box and found the negative wire connection melted.  I think that’s my issue.  I just replaced the wires and the sub is now back!  Going to tune the boat speakers with the sub on the lowest setting and then I’ll be back out on the water!  Thanks guys!
