Blown subs i just got 2 12" orion subs from my friend. when i hooked them up i got nothing and relized that i couldnt even push the sub in with my hand. i came to the conclusion that its blown/frozen up but i was wondering is there any way i could fix the sub since my kicker is on its way out. any information on this would be appreciated.

Generally, when woofers freeze, the coils weld themselves to the magnet structure. It wouldn't be possible to repair them without the required replacement parts. Even if you could get the replacement cone/voice coil, the magnetic gap and the area around it isn't likely to be in good enough condition to accept the new parts. With only a few exceptions (Digital Designs and other high-end woofers), woofers are disposable if they're not under warranty.

Hi there, i have a orion cobalt 2105xp 400. i have hooked all up, but very little bass. i have 1 10" boston acoustic sub. i noticed that the led is constant red, is it supposed to be green, crossover...


amp is in protect mode. check your wiring and make sure your sub is wired properly for ohms. dual 4 ohm in parallel = 2ohm. dual 4 in series is 8 ohms. dual 2 ohm parallel= 0.5 ohms and in series 4 ohms. check ground and power wires. make sure sub isnt blown. a blown sub WILL cause this on any amp.

Orion xtr15 to a american leagacy la 660 amp


your only choice is to run the amplifier at a 4 ohm mono load - this will not reult in the amplifier making much power.
Positive on sub to Positive on amp.
Negative on sub to Negative on amp.
This is your only possibility.

Adding a second sub in the same fashion will result in a 2 ohm load, and your amplifier will run at its rated potential.

How to wire 2 dvc subs to a orion 2150sx ? dont know the wire colors or how to hook um to my amp.


what impedence are the voicecoils?
Dual 4 - Dual 2 - Dual 1 ??

Orion SX / GS / HCCA amp Wiring guide:

Orange = Right Positive
Black/ Orange = Right Negative
Yellow = Left Positive
Black/ Yellow = Left Negative
Blue = 1+1

Bridging of SX or HCCA Amps:
1. Use the Orange wire for Positive.
2 Use the Black/ Yellow wire for Negative
3. Push "in" the Mono Button
That amplifier is only 4ohm mono stable - so assuming the subs are dual 4 ohm voicecoils...

First wire both in Parallel Independently So each subwoofer is now a 2 ohm load. (combine + and + - and- on both subwoofers)

Now Take a positive on one voicecoil of sub #1 and attach to amplifier+(orange)

Take a - on that same subwoofer and attach it to a + on the OTHER subwoofer.

Finally, take a - from the second woofer to the amplifier -(black/yellow)

Now you have a 4 ohm load on your bridged channels.

KAC-9102d no sound, Amp powers on but no sound to the subs.


If the sub isn't working, you won't get a pop. All you need is a small speaker. Don't need a sub, you just want to test the sound. I recently blew 2 subs, no smoke, no smell, no sign of being blown. Absolutely nothing from the subs.... In the past my sub locked up. You can take your sub out of the box and hook the + and - to the battery to see if you can get the sub to pop there. I believe a small box will push a sub into a deep excursion to the center of the cone. I have 2 lanzar VW12D's that just quit. I hooked a 6 x 9 up to my amp and low and behold I had sound! Try that and see what you get...

Blown subs


My big question would be "Did your friend know the subs were dead when he gave/sold them to you?" If so, he needs a swift kick in the ***.......But onto your question.

If the cone doesn't move at all, or there's a scratching sound when it moves, you've definitely have problems. I have no firsthand experience with speaker repair, but I do know it exists. A quick Google search for "speaker repair" can give you some ideas for places to ask. Keep in mind, most of the speakers that get repaired are those that are discontinued, classic, or otherwise expensive enough to make the repairing of it a better option than replacing it. In your case, it may be the same price to repair it as it is to replace it.

Sub does not operate


There could be many issues, from fuses in your amp, to power getting to your amps, to "low" impedance on your amp, and the circuit shutting down. Or it could even be your head unit, perhaps there is a setting on the HU that turns ON/OFF the subwoofer. BTW, you are running to low of an impedance on that amp. If my memory serves me correct, the lowest impedance that they JL Audio recommends is 1.5 Ohms.

My amp works but my sub doesn't...!!!????????????


Whats the condition of your amplifier? New , Used, Old?

 

You might have a blown channel off your amplifier, this may cause little or no sound. You will have some distortion, crackle sound and then maybe nothing at all. What kind of subs are you running to it? Make sure the subs arent blown and check the voice coils to see that they are not torn off the subs , these are the 2 little silver or copper wires that are connected from the speaker connectors to the sub itself.

 

Let me know what happens?
