subs and ohms

They're obviously not all identical subs, but if they are not same brand and size...wipe the slate clean and don't use this combination.  No use buying an amp or amps for a sub combo that won't behave.  Now, if they are same brand and size, all being equal except for coil configuration, and you insist on using all three of them, use separate amplifiers.  You want to be able to control the power so that all three subs perform the same (as much as is possible).

A two channel amp for the two single coils and a mono amp for the DVC.  You could also look into the 5 channel amps and you'll have a pair of channels left over for the front speakers.

But nevertheless, post model numbers of these beasts per forum guidelines for best advice.

Alright.  One last chance, hatch.  The model starts with "SWS...".  We can do some research and find a DVC 4 ohm sub, but no single 4 ohm.  Tell the forum what you are working with.  And be specific.  If you're mixing up various brands, step #1 of my previous post applies and we're done.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Okay.  These subs are not terribly dissimiliar, and efficiency is about the same.  They both use a sealed enclosure of about 1 cu ft per sub.  But the best advice is:

Use just the two 1041s wired together in parallel to make a 2 ohm load.  Build a nice 2 cu ft (internal size) box, sealed.  Use a mono amplifier that is rated at up to 500 watts RMS output at 2 ohms.  With good clean installation and careful gain setting and positioning, you'll have a nice sub system.

But if you are hellbent on using the combination of the three subs, you can do that if you wish without severe problems.  I would advise using separate enclosures so that you don't stick yourself with a three-holed box that is difficult to find a good combination of subs for.  You should use a 2 cu ft box and a 1 cu ft box, internal airspace after all displacements have been accounted for.  All should be sealed.

Wiring would look like:

This is a series/parallel wiring configuration.  The DVC 1042D would get about the same power as the two 1041s combined, but that might not bother you and it may work out okay when all is said and done.  The load is 4 ohms, so you can use any type of amplifier.  Probably best to use a two channel amp that is rated for bridged output of 600 watts at 4 ohms bridged.  This would equate with a stereo rating of 2 X 300 watts at 2 ohms, so double-check that in the specs.  You can use less power, but no more than this.  And this is RMS output, not "peak" ratings.

EDIT:  I just saw haemphyst's post.  That's interesting....hmm.

Yup.  I agree with  Dave's wiring.  Disregard the connection between the two 1041s in my pic, and just let the wires exit the box individually for those two woofers.  Here is a wiring diagram complements of BCAE1.com:

All else I said about power still applies.

Here's a new diagram.  I fixed it.

ok would this one be good?
