Question about DVC

[Cozmoo]

Hey, I just bought a 12" Rockford P3 off of Craigslist and at the moment I only have it wired to one coil, which I know is bad and am working on hooking up the DVC.

I have a 340watt dual amp that I am using bridged.

should I hook up both coils while bridged, or should i use one channel per coil?

The woofer on the rockford site says min 150watts maxx 500

It actually will not hurt it to run just one coil. It will only handle half the power, but it will not hurt it. . .

What impedance are the voice coils, and what is the minimum impedance rating of the amp?

need specs on amp and sub

[Cozmoo]

Sorry I took so long, been really busy.

The woofer is a 12" P312D2 Dual 2 Ohm 500 watt RMS 1000 watt max

the amp is a 340 watt Dual XiA2346 2/1 Channel Amp

My current setting is I am using it bridged on one coil.

I bought this sub pretty new off of craigslist because my old 12 for some reason blew and won't play over 15 volume, because the amp would go into protect.

My friend tuned this amp by ear because none of us have O-Scopes but I switched the Crossover from Full to LPF, so now it just plays bass instead of music. I have no idea what the Input level or Crossover Frequency is on. But the input level goes from 6V to 200mV and the Crossover Frequency goes from 40Hz to 400Hz

Right now, if I have the SUB setting on my headunit set to 7-10, if I turn my volume over 18, my sub wont play when bass hits(the amp goes into protect). I don't know if it is a problem with my amp, but sometimes my car doesnt start..like it is totally dead until you touch the negative terminal on my battery, then it starts up. I think it needs cleaning, that might solve it.

But yeah, those are the specs.

I hope you can help on how to set it up.

Do you have you sub wired up to 4 ohms or down to one ohm? If its one most likely your amp won't handle one ohm while it's bridged which is why its kicking into protect.

Edit: just seen your only using one coil. NVM What ohm is your amp stable at while bridge?

if its four id hook the other coil up and wire it to four ohms.

Wire the sub like this and bridge it. Right now your sub is wired up at 2 ohms and your amp can only handle 4 ohms bridged thats why it is going into protect.

^ Yup Yup

my amp said 200 Watt x1 @4ohms bridged.

whatever that means.

it also said Do NOT use 2 Ohm speaker load in bridged mode.

that is probably why it was cutting out.

I understand that picture to an extent.

I understand you do the positive to the positive on coil one. and the negative to negative on coil two.

but what about the right side of the picture where it goes from negative coil to positive? how do I hook that up?

Well since you used a positive from on coil and a negative from the other coil you should have an open positive on one side and negative on the other just run a piece of speaker wire to them connecting the two.

Easy. You just hook a wire from the negative on one coil to the positive on the other coil.

It's series wiring.
