Can someone explain it to me please? how should i wire a SVC sub

just the first + to the First -?

yes, or first - second + second - first +

it really doesn't matter

then whats the extra 2 connections for on a mono block?

Bridging it? For you can run 2 subs?

 

[bballrrt06 10+ year member]

they're wired internally parrellel i think. so yes, you can hook two subs directly up to it.

it is simply for ease of installation...

Coo that works

I guess i got figure out how to wire it to 2 ohms when i get my second SVC.

I know how to if there was only 1 + and - but now this kinda complicates things.

?????

Im still a little confused on this matter

If i wanted to run a 2nd SVC sub should i just run each sub to its sepearte channel, but then i dont know if it would take it down to 2 ohms.

yea its pretty weird..my subs look funny wired up to it. but they are very good amps for the $$$.

They're bridged internally, don't worry about it.

swseeet thanks!

no they're not. It's a single channel amp - one in, one out - no bridging going on.

As Bballer said, they're parallel inside the amp.

There are two sets of terminals simply because with an amp that powerful you may be running 4, 6, 10...who knows how many subs, on top of that there may be multiple voice coils to wire. In some cases there may need to be several speaker leads from the amp - that is why there's 2 pair.

If you connect a 4 ohm load to each terminal the amp sees 2 ohms. Alternatively, just run one pair of spkr wires from the amp and do your parallel wiring from sub to sub.

"They're bridged internally" is the short version....

Hmmmmmm... so i can just keep it the way i have now which is 1st + and 1st - have wire running into them and do the wiring to the subs with 2 SVC's and then do my parallel wiring see a 2 ohm load.......

OR...

wire one sub to 2 terminals and the other sub to the other 2 and then it will see a 2 ohm load.

exactly.

no, it's the wrong version.
