Ok, so I'm going to be making a purchase on amp(s) and sub this week and wanted a little more info..

I'm more than likely going with the same Alpine Type-R DVC 10" sub that I had before.. the stats on it are the following:

~ Dual 2-ohm 2" voice coils
~ Frequency response 28-1,000 Hz
~ Power range 100-300 watts RMS (150W per coil)

Now, does this suggest I should wire it in parallel if running a 300x1 @2 ohm amp? Or is there a better way to be doing this?

Or should I get the 4ohm version of the sub, and then find an amp doing 300x1 @ 4ohms? Would the two voicecoils also be wired in parallel in this scenario?

 

ok, if u get a dual 2 ohm sub, series will give u 4ohm and parallel will give u 1ohm.

if u get dual 4 ohm sub, series will give u 8 ohm and parallel will give u 2 ohm.

if u want to get a 300x1@2ohm amp, u should get the dual 4ohm sub and wire it in parallel

if u want to get a 300x1@4ohm amp, u should get the dual 2 ohm sub and wire it in a series.

to better understand wut im saying take a look at this diagram http://paudio.tripod.com/subwooferwiring.html

 

is one way better than the other? as in, is parallel better than series for any reason, or vice versa?

 

not really. but why would you want more impedence? it just causes you to need a more powerful amp.

 

If you wire it in parallel your amp will be presented with a 1 ohm load. Many ordinary amps won't be able to handle this low impedence, if you have a mono class D amp it should go ok.
If you wire it in series, that is wire one voice coil to each channel of a 2 channel amp, then the amp should handle it fine but you should make extra sure you have a mono signal going to the amp and you have the gains set up so that each voice coil is getting the same signal or you may blow or damage your sub. Take a look at the diagram on the site that other guy posted and wire it that way.

If you get a dual 4 ohm sub and wire it in parallel then it will present a 2 ohm load to your amp. If the amp is an ordinary 2 channel amp then you will have to bridge it in order to run the sub in parallel so your amp will be running at 1 ohm. 1 ohm will damage many amps.
If you get a dual 4 ohm sub and wire it in series it will present an 8 ohm load to your amp. The amp will handle this fine however you won't get the most out of your amp and won't be putting as much power into the sub as you could.

I would say: Get a dual 4 ohm sub and a mono amp which is stable at 1 ohm, or
Get a dual 2 ohm sub and a normal 2 channel amp but be careful to set the gains the same for each channel or,
Just get a normal 4 ohm SVC and an ordinary bridgable amp.

 

ok, more complications.. what if I were using a DVC 6ohm sub like the JL w3v2? How would you wire either a 4ohm or 2ohm amp for that?

 

no it's either 3 or 12 then. half and twice as much no matter what. Unless you have more than one sub

 

yeah.. that's what I thought.. I've never seen a 3 or 12 ohm amp though..?
