Thread: Sub and Amp question?

What is the specifications of the amp? RMS wattage at what input impedance?
What is the specifications of the sub? RMS wattage and what is the impedance of each coil?

I dont think that your sub is capable of running 2, 4, or 8 ohms. most likely 2 or 8 ohms.

Aye, really sucks when you're asking for help, then being a jerk off with a helpful reply, and on top of that having no idea what you're talking about.

I'm sorry, I don't normally get combative on the forums, but this just irks me.

First off, your sub is NOT capable of running 2, 4, or 8ohms. This is a physical impossibility. Secondly, if the sub does indeed have 4 positives and 4 negatives, it's not a dual voice coil subwoofer. It's a quad voice coil subwoofer. Either that, or it is a dual voice coil woofer that just has split inputs for easier wiring. This could be the case. Either way, it doesn't matter. You need to find out exactly what it is before any one can give you any sound advice on how to wire it.

Here's the problem with your 2, 4, or 8ohm wiring.

If it's dual 4ohm, you can only run it at 2ohms (bridged, or parallel) or 8ohms (series).

If it's dual 2ohm, you can only run it at 1ohm (parallel) or 4ohms (series).

That's it. There's no subwoofer (that I'm aware of) that can bypass ohms law. It's simple scientific fact and there's no way around it.

Never knew lower end companys made quad voice coil woofers. Please post a pic. Lets just plug it into the wall free air, that'll be fun

ehm hardcorejuggalo..... PT and digital are 2 different companies...., so the subs aren't in any way the same

@ronjon.... Not totally correct, since besides parrallel or series, you could also wire in stereo.... Which isn't recommended, but still, it's possible. so if it is actually a DVC 4Ohm sub, yes, it could run in 2,4 or 8 Ohm

@hardcorejuggalo: it isn't recommended to wire the sub in stereo since alighning the input on both VQ's without measuring the output of the 2 channels will result in crappy sound. And besides that, with your current amp it isn't possible anyways, since it's a monoblock. So in that case, yes, you can only run the sub at 2 or 8 Ohms

@ arcanedreams..... I've already earned my credits on this forum, so I guess I know what I'm talking about. I never said it'd sound good giving each VQ its own channel. I only said it was possible. I also said that, in that case he could only do so by aligning output on both channels, which cane only be done by a scope or DMM. I've provided the TS with some info, and that's why I get the thank you, as opposed to some other people who are making a joke out of it. If you want to know my experience with car-audio, maybe you should do a search, because I'm pretty sure it's far more than most of the guys here, along with a few respectable members like redGTIvr6, scott-fx, durwood, turbocad6..... You, my friend still have to earn those credits, so don't come to me telling me I don't know a thing about it.

Oh..... And again YOU showed you don't know ***** what you're talking about. If it's a DVC 4Ohm sub, he could also wire it in 8Ohm. An amp tha puts out xxx watts at 4Ohm is also able to play at 8Ohm... Given it will be with a lesser output. But since you come off as being a know-all, you should know watts don't matter, but efficiency does.
