help me understand.

I'm having a little bit of trouble understanding stuff to do with wiring. With this sub, here - Subwoofers | TS-VR10 why does it looks like there are two sets of + and - terminals. If there are, and it says "Impedance - 2x4ohms", then how do you wire that to 2 ohms, or is it already wired for 4, or what, how do you even hook it up do you need a 2 channel amp to run 1 sub? maybe i'm completely wrong. Help me out haha.

you can either run the Sub at 2 ohms or 8 ohms

if you want 2 ohms then run your positive wire from your amp to both of the + wires on the speaker and do the same for the - wire

This puts both voice coils in "parallel" and you will have 2 ohms to your amp

i've never seen a sub where you can hook up the voice coils individually is it a common thing or what

well it is alot more now a days. more versatility for using the same sub in different setups(multiple woofers). You always want to use the two voice coils together. In parallel as above mentioned, or in series to give you the 8ohm load. Thats ideal if say you added another of the same woofers. then youd wire them both at 8 ohms and runing together on a monoblock or bridged 2 channel your amp would see a 4 ohm load.

so, if i run two of those subs in series on a monoblock it will be 4 ohms? now i'm confused again because i thought when you wired it in series it doubled the ohms, so for instance two 2ohm subs would become 4 ohms, and when it was parallel it decreased it from for instance 4ohms to 2ohms

with a single voice coil sub you only have one pair of terminals, so if that sub is a single 4ohm then when you hook it up the amp will see 4 ohms. think of wiring dual voice coils like you would 2 subs. (1) dual 4 ohm sub wires to the same impedances (electrical resistance measured in ohms) that (2) single 4 ohm subs will. wiring a dual voice coil sub in parallel results in halving the impedance of it, wiring it in series doubles it. to run it in parallel, you would run wires from both terminals to the amp. to wire it in series, you put a wire connecting the + and - of one of the coils, and the other coil is run to the amp. hit me up on chat if you have any questions

one more question. since it says the RMS on that sub is 300 watts, that's 300 watts for both of the coils right? and also, is that 300 watts at 4 ohms, or at two. Let me just explain what i'm doing here actually. I have already an Audiopipe AP-3002. its 2x320watts @ 2 ohms. So if i wire the sub itself in series, but then use 1 sub per channel on the amp, thats 320 watts RMS going to each sub, at 2 ohms, right?is this too much for the sub, because i'm not sure if the sub is for 320 watts at 4 ohms or at 2. Sorry if i sound really retarded or something i'm new.

If you have a pair of DVC subs and each coil is 4ohm; you have 3 choices;

1.Wire the VCs in series (8ohm) and run each sub in parallel with each other to the amp (4ohm load)

2.Wire the VCs in parallel (2ohm) and run each sub in parallel with each other to the amp (1ohm load)

3.Wire only 1 VC to the amp and parallel the subs (2ohm) while shorting the other VC's (run wire connecting the leads). This usually alters the sound of the sub and makes them a little boomier.

While it looks nice in a brochure, DVC subs really don't make much sense to me as you're still painting yourself in a corner. Buy 1 sub (4ohm DVC) and you can run a mono amp. Add another sub? You're now running at 4ohm and the amp isn't seeing enough load to make power. Conversely, if you buy 2 subs you can wire them up for a 4ohm nominal load. Get rid of those woofers and replace them w/a single better 4ohm DVC sub? You'll blow your amp.

PITA if you ask me.

dual 4 ohms are convenient because they wire down to 1 ohm. you can achieve that with single voice coil subs, but i have yet to see many single 2 ohms. plus, dual voice coil subs allow you to push more power to them simply because you have more terminals to attach wires to

ok, so then is this possible. With a 2 channel amp, wire the VC's on each sub parallel, so that each sub is 2 ohms, and then run it in stereo from the amp. Wouldn't that be the best way? that way you are running 2 channels, each one at 2 ohms, am I correct?

if you are running each coil on each channel that's actually 4 ohms on each channel. it works different than running a mono amp. if you wire a sub in parallel to a mono amp, it will parallel it inside the amp internally. 2 channels and others don't usually do that.

 

[caraudio93 10+ year member]

ok, so one sub on each channel at 4 ohms per sub won't work. Should i ditch this amp, and buy a monoblock then? or what do you guys honestly think the best way to wire two of those subs i posted earlier to the AP 3002 2 channel amp is?

 

[Kangaroux 5,000+ posts]

oh, you have 2 subs? lol didnt know that. that amp should have a mono/bridged switch, or at least a wiring guide on how to achieve a mono load. you want to wire your 2 subs like this:

that amp does roughly 600w when bridged, so thats 300w a sub

 

[caraudio93 10+ year member]

yes, i have two subs maybe i forgot to mention that, sorry. Anyway, that's exactly what i was looking for thanks so much. And that's perfect because the subs are 300 watts RMS a piece. so it looks like it will work out nicely.
