I need help. I bought a ten inch Bazooka tube DVC 4ohm, and I have a Power Teknique 400w x 400w 2 channel amp. Whats the benefit if any in bridging it, running it in a series, or parallel? Any help will be greatly appreciated.
Thanks for the quick responses. Andrew Capps, what do you mean "if the amp can handle it" are you talking about the ohm load? I looked up the specs and Maximum Output Power @ 2 Ohms: 400W x 2CH Power Output @ 2 Ohms: 175W x 2CH Power Output @ 4 Ohms: 125W x 2CH Power Output Bridged: 350W x 1CH
It also said the amp is 2 ohm stable. I haven't yet had time to hook it up bridged then parallel, but I will let you know. Currently I have only one voice coil hooked up to the amp and the sub has a lot of distortion that sounds like crap. It hits a little but when the music is low you can hear the distortion.
You can. Each diagram illustrates a different way of connecting components in a circuit.
In the first diagram, you are wiring the voice coils in parallel, which gives you a 2 ohm impedance. This is due to there being 2 paths for the electrons, therefore less impedance.
In the second one, the coils are wired in series. Because the electrons have to travel through both 4 ohm coils before the can complete the circuit, the impedances are added. This gives you an 8 ohm load.
Remember the terms "parallel" and "series".
Series: add resistances. Parallel: Divide 1 by each load (unit = ohms) then add your answers to get the final load (of course, this omits resistance from your conductors, terminal, etc.). Example using yours: 1/4 + 1/4 = 1/2 (the reciprocal will be your load). I didn't explain that well but the example should make it obvious. Now, when it comes to speakers, we usually deal with equal loads, so you can usually just divide the IDENTICAL load by the number of components. Example: two 4 ohm voice coils = 4/2, which equals 2.
There was something else I wanted to say...
Right. Impedance is used when the load is reactive (resistance changes with the frequency of the AC). Speakers are reactive loads. Resistance is used when the load is constant.
There was something else.
I dunno.
Just please say "impedance" instead of "the ohms".
Cam, thanks a lot that was actually very helpful. I still have the same problem I did with my 12's though. I just got rid of my two 12's because they had so much distortion, now the same thing with this new sub, its just not clean. Could it be my amp? The amp is about 5-7 years old.
