It depends on whether you want to wire them in series or parallel

series-put a wire between one of the red and black and leave a pigtail put another wire between the other red and black and leave another pigtail use one for positive and the other for negative
parallel- put a wire between the two reds and leave a pigtail put a wire between the two blacks and leave a pigtail- use the blacks for your negative and the reds for your positive
1=positive(red)
2=negative(black)
if your amp has a 4 channel output don't wire the 1's and 2's together- .wire them in pairs of 1 + 2 to each of the amp outputs

How can I hook up BIC F12 subwoofer to Onkyo TX-DS838 receiver? Will the receiver power the subwoofer and other speakers?


Get a RCA cable and connect from your amp where it said Sub Woofer in the Pre Out box in the back of the amplifier top left hand side and take it to the "Sub In" located in the back of your Sub woofer bottom right hand (White round connector).
Good Luck!

I need to wire 3 woofers but 2 are dual voice coil and one is single voice coil


sure, if you wish to wire them all together, wire the first dual voice coil subs first voice coil negative to 2nd voice coil positive, second voice coil negative to single voice coil sub positive, and single voice coil negative to 2nd dual voice coil subs 1st voice coil positve (again with the second dual voice coil sub, run the first voice coil negative to the 2nd voice coil positve) your speaker leads will be attatched to first dual voice coils 1st voice coil positive, and 2nd dual voice coils 2nd voice coil negative)

I have just run a bass test and I am getting bad vibration noises from one of evp subs the sub works but seams to crash at certain frequancies


Over-driving or resonances can be unpleasant and intermittent. Decide which you have. Find some music that causes the symptom.

If you haved two identical subs the diagnosis should be easy enough. Swap them physically.

Lower the volume. Problem solved?

Move the sub around the room to see if it changes for the better or worse. Room boundaries and YOUR position relative to the speakers play a huge part in bass response.

Maybe the speaker cone is damaged or the voice coil is separating.

I have a Fisher RS-909 Surrond Sound amplifier. It has no "sub out" jack. I had the sub-woofer working in the past by wiring it as shown in the manual. The problem is that the system was in...


Alright i had a chance to look over things, this is how you are going to hook up the sub. first we'll be connecting the surround sound unit to the sub woofer.
surround sound unit sub woofer
left front: positive (+) <-----to------------->(+) left speaker level in
negative ( - )<- - -to- - - - - - ->( - ) left speaker level in

right front: positive (+) <-----to------------->(+) right speaker level in
negative ( - )<- - -to- - - - - - >( - ) right speaker level in

now that the surround sound unit is connected to the sub woofer you will need to connect the front surround sound speakers to the sub woofer.
sub woofer front surround sound speaker
left speaker level out (+)<-----to--------> (+) left front speaker
left speaker level out( - ) <- - - to- - - - ->( - ) left front speaker

right speaker level out (+)<-----to--------> (+) right front speaker
right speaker level out( - ) <- - - to- - - ->( - ) right front speaker

Alright now that the wires are all over the place and plugged in
turn everything on and see how it sounds. let me know if everything is working as it should. if you need help with anything else or if something does not seem right please feel free to contact me via e-mail or phone

Some weeks ago the sub stopped working. Thought dog had chewed the coaxial driver cable, but not shorted (now). Tried another sub w/o success.


Hi, I went to the Denon website and they have no documentation there for your receiver.
But do not frown, I have some good suggestions for you.
0 Don't beat the dog. After all, it's their job to chew things.
1 Get a new, un-chewed cable and see what happens between the sub output and the sub woofer. If it works, your in business. If it does not work. Don't be discouraged . Go to step #2
2 If the sub output on the Denon has failed, and everything else is good. There is another way to use your sub.
Install a patch system using the Headphone output from the front of the Denon. It may seem odd, but it works exceptionally well for the following reasons. It works on all signal sources. So if you are not playing a home theater source, you still have the use of your sub.
You will need the following adapters.
1 A Male stereo phone jack to female mini-phone jack. (Something that would accept typical small headphone sets such as those on an iphone).
2 A stereo "Y" connector that that has a single stereo male mini-phone jack that has two "RCA" female jacks.
3 A simple RCA male to male stereo cable pair as is commonly used to connect CD players, etc. i.e. separate red and white RCA connectors at both ends.
1 and 2 above may be available as a single unit combined with each other.
Take these adapters and connect the Item 1 into the Receiver, Item 2 plugged into Item 1, Item 3 plugged into Item 2 and finally the other end of Item 3 plugged into the two female RCA jacks mounted onto the back of the sub-woofer. If the sub only has one female RCA connector, get a RCA "Y" connector that has a single male end to 2 female ends.
This setup will work perfectly with any sub. The reason is as follows. Most decent subs have an adjustable high frequency cut off. So you can vary it from about 20Hz up to about 140 Hz.
I recommend that it is cut off at 80 hz. This way the bass transition is usually seamless between the woofer and the rest of the system. .
Then adjust the woofer volume control in a similar manner.
If it all works out, give the dog a treat and enjoy yourself.
I really hope this helps, I love my sub woofer as well.
Let me know how this turns out.
If you have any questions please post them on the site and I'll get back to you ASAP.
Best Regards,
Mark

I bought a 300 watt amp and 10in type s sub. i wired up the sub bridged on Chanel 3 and 4 like the directions told me and had a cross over foe the duel voice coil. it was fine for about a month then it...


You are reaching the physical limit of the drivers' range of excursion. It is also likely that at least one of the voice coils has thermal protection and when you disconnected the crossover you also disabled that protection...thus no "cut out."
As for "bottoming out" you could either reduce the volume, or modify the subwoofer enclosure so it will reduce the amount of the cone movement.

Sub digital coax connection


You will need to get a y connector and split the sub out signal between the one it came with and your additional sub. The connector you need is an MFF, (1-male, 2- female) RCA type.

Good Luck,
