Wiring DVC Speakers & Box size

here's the deal. i've had these two 8" punch DVC speakers for like 14 years now and have never used them. I built a sealed box to the dimensions recommended in the manual. I remember wondering if i wired them right because they have two positive and two negative terminals on each speaker. I wanted to be able to run one channel off the amp. so i hooked them up once i built the box and they didn't thump at all. either my amp was too small or they were wired wrong. Can anyone help me with the wiring. I dont understand the wiring diagram in the manual and i dont understand why there is two positive/negatives on each speaker. Also wondering if a sealed box to the recommended CF is too little? any help?

oh yea. what kind/size of amp would work good for these speakers?
thanks

bump. still looking to get an amp for these. after some research i think one terminal is for the woofer and the other is for the coil.

Its dual voice coils. Offers more flexibility for amping them. 'If' they are dual 4 ohm coils you can run a 2 channel amp @2 ohm load or a mono/bridged 2 channel amp at 4 ohms. Sounds like a bridgeable 2 channel would be best bet for the speakers you have. You would wire them parallel or series based on which way the amp puts more power. (Bridged to 1 channel 4 ohm, or straight 2 channels @2 ohm)

Check this one out.

Should only need the gain at a third to half max which will give you cleaner power and work the amp less than if you 'match' the max rms power on the sub.

Gonna try and verbally explain the wiring. Could google dvc speaker wiring for a diagram.

Parallel. Will make each dvc 4 ohm speaker to 2 ohm impedance. Pair of wires going into box to one side of speaker. Pos to pos and neg to neg. Then have short wire jumping from that pos to the other pos. Jump neg to other neg on same speaker of course. Do the same for the other speaker. This would work best with a 2 channel amp not bridged OR a mono amp that is stable at 1ohm.(usually expensive and draws a lot of power)

Series. Will make each 4 ohm dvc sub 8 ohm. When you join 2 of these it will be 4 ohm and safe for any 2 channel amp to bridge to. Start with pos to pos and neg to opposite voice coil negative. Use one jumper from open positive terminal to the open neg terminal on other (voice coil) side of speaker.

Hope you understand this. I think bridging a 2 channel to both subs wired in series will get you the best sound.

Lastly. Search "sub hookup" thread in this forum. There are some pictures and links in there that can help you out. I'm out...

Series is just positive to negative to positive to negative. Flow of electricity goes through one before the other.

Rockford Fosgate® - Woofer WiringWizard

Select 2 woofers, DVC 2X(whatever your subs are rated for - 2 or 4 ohms), then click search...it'll show you all of the options.

The JL Audio amp should work, you just won't bridge it...I'm thinking to run that one, you would run one sub on one channel and one sub on the other, wired in parallel (+ to +, - to -). Been a while since I've messed with car audio.

I had this amp...it's really nice...you can find it cheaper on Amazon. I think I paid $130 when I bought it a year or so ago.

Yes please. All I have seen is either +/- or red/black. What sub(s) are you hooking up?
Never mind, you told already. Just read back to your first post. A pic would help to understand what you are dealing with.

here are a couple pix. the second pic shows the purple dot however the camera flash makes it look white. these pictures are of the same speaker and taken 180 degrees from each other. i just spun the speaker around to get the 2nd pic.

I can't see anything in that pic on my phone. Mine are marked on the black cardboard type piece that the terminals mount to with a + or -.

Here's how you tell. Have a black or red sharpie to mark which is which. Attach a short speaker wire to a set of terminals like the first pic.

Get a fresh 9 volt battery and touch to the speaker wires. When the speaker moves outwards like the 2nd pic then the terminal corresponding with the + on the battery is your positive. Repeat for other side and refer to wiring diagrams based on what load you want to put on your amp.
