About the only thing that could cause it would be if they were hooked up while installing and shorted them out some how.. or it was dropped.. test your coild with a DMM and see what the impedence is on them if there good it should read 4 ohm if thats what they are if DVC check both sides. if the read real low then coils are shot.. replace with recone.

Sometimes the Bazooka tubes have an internal amp. I am not sure of this model but maybe you can Splice in directly to the Speaker Wire and bypass the AMP in the Tube if it has one

SOURCE: I hooked up a 2-Ohm dual voice coil 800 watt max

off the same amp? you have two way different sounding speakers man. you can buy 2 identical speakers from the same company and brand and series and they will play differently every time. you have 2 speakers with nothing in common so you will hear a difference and maybe interference because of the different ohm levels.

SOURCE: Volfenhag ZX4725 i am buying this subwoofer and

No the LOWER the resistance the MORE Output or Draw, If say it is 100 Watts into 4 Ohms, if you used a 2 ohm speaker it would draw 200 watts.(only if capable of delivering that amount of power) The LOWER the Resistance, the HIGHER the Current Draw. WATTS = AMPS x VOLTS. (This is not strictly true with amplifiers output though, as it is an AC Current, and a "Reactive" load, it has, Inductance, Capacitance and Resistance, all in one.and is worked out via a Formula) see below. http://en.wikipedia.org/wiki/Audio_power

http://www.hometheaterhifi.com/volume_1_1/v1n1spk.html

Now with Dual Voice Coils, Essentially, you can think of these speakers as TWO speakers in ONE enclosure. As such, They are basically TWO Speakers. Please see the website below it explains everything for you. http://www.diyaudioandvideo.com/FAQ/Wiring/
Everything is a function of Resistance and Ohms law.
Current (I) = Voltage (E) divided by Resistance(R).
Voltage = Current Multiplied by Resistance.
Resistance = Voltage divides by Current.

I have a s12l7 only one voice coil will work


sorry to say you have burnt on of the coils out open circuit. it probably will not be long now before the other coil blows as they are wound together and one can damage the other during burn out.

I have a subwoofer in my truck. 2 speakers in a box with an amp. One of the subs blew to a song that just came on. the volume was high. Sounds distorted. Any way to fix?


Sounds like the voice coil of that woofer overheated and melted while it was turned up too far. Now that area rubs on the magnet or pole piece internally and makes noise.

No you generally can't fix that except for a few high end woofer brands that have field replaceable voice coils that you can buy. Most subwoofers physically bottom out and sounds really bad before experiencing thermal damage like that. Sounding bad is a warning sign that it's being overloaded.

Note that woofers have 2 different types of overload conditions that can cause damage.
1. Over excursion from deep bass that moves the woofer cone too far and damages the suspension. This is clearly audible. Proper box design and user knowledge will prevent this.

2. Thermal limit. This is the published power rating that the voice coil can absorb without damage. Things can melt or fail entirely if this is exceeded.

Either of those issues can cause the noise you are hearing. Without a more detailed description of what happened or how it sounds before, during and after this is much detail as I can provide. But.. move the woofer some by hand, do it evenly pushing straight down evenly on both sides, not too far, go about half way through it's normal movement. If it clearly rubs and makes noise internally then the voice coil is damaged or if has some debris stuck in there. Most woofer are not serviceable.

There are many other factors that affect the longevity of the woofer, such as
  • Ambient temperature too high
  • Limited air flow has inadequate woofer cooling
  • UV exposure can make the surround material brittle
  • Proper enclosure design is needed to acoustically and physically supports the woofer to prevent bottoming out, particularly at the system resonant frequency.
  • Amplifier distortion can kill speakers even when rated far below the woofers max wattage.

Hello the bazooka power wont come on


So it is a powered tube, yes? Can't remember, does the Bazooka have a fuse on it? If it is powered, you blew the board.

Checking voice coil


Are the connection tight? Do you have a good ground? Does the coil, when pushed down gently, move freely? If it moves rough, the coil is bad. check those.

Popping during action scenes at moderate volume


the woofer is being overdriven and the voice coil is hitting the magnet structure.eventually it will damage the coil end and it will scrape in the gap.
