Owner's manual

You'll use fig.8 for the front speakers and fig.9 for the subs.

I found a pair of Aiwa SSX-VX77F tower speakers in my uncle's garage. They have two sets of connections (for different speakers,I guess). Anyone have an owners manual they could share, please?


The Blue & Black wire is for the full-range speakers (Blue=POS and Black=NEG)

The Red & Black wires are typically the low-frequency driver.

Sources: I have owned some speakers in the past and seen a set of wiring with different color coding. Hope that helps!

Do i hook the speaker wire in to the top or bottom wire recepticles of the speaker


These are bi amp capable speakers...if you have the jumper in place (connects top and bottom terminals together) it's set up for standard full range connection - you can use either set. If the jumper is not in place, it's set up for bi amp which means you would connect your low frequency wire to the bottom terminals, and the high frequency wire to the upper terminals.

Cerwin Vega SUB8...how do I connect


grady66,
We will start with the easy one, Phase. The phase selector is a setting that can be adjusted by sound; which one sounds better? Either one will work fine. It's mainly for situations where the sub enclosure is located at a distance or behind the listening area. The 'in and out' crossover selector and the input from the receiver goes together. The 'in and out' crossover selector is asking if you want to use the internal crossover to block the bass from getting to the satellite speakers. Most home surround sound receivers only have the one sub out and most subs have both left and right inputs. When there is a single signal being fed to the sub you use the subs left input or buy a splitter and send the signal into both left and right, but either way will work equally the same.

There is two ways to connect the speakers to the receiver.

1) Cross-over 'In': you connect the output speaker wires from the receiver to the speaker inputs on the sub and the speaker outputs on the sub to the satellite speakers; the sub will get its sound from the input speaker wires.

2) Cross-over 'Out': you connect the sub to the receiver using the receiver's single sub out, then connect the satellite speakers directly to the receiver's speakers outputs; in this configuration the satellite speakers are given a full range of signal including the bass.

I have used #2 with the same system and had great results.

IF THE WOOFERS HAVE 2 VOC.COIL EACH HOW DO YOU CONNECT WITH THE AMP THAT HAS ONE CHANNEL WITH TWO + AND TWO -.


it depends on the load you want to present to the amp. un 12, 2009 - If woofers are 2 coil, then you definately need to know the impedance of the coils (are they dual 2 ohm, or dual 4 ohm?). For dual 4 ohm speakers you will only be able to acheive a summed load of 1 or 4 ohms. If your amp can handle 1 ohm, then connect this way: 1 ohm: Connect both the positives and the negatives together on each speaker. This puts them in paralell which will result in a 2 ohm load per speaker. After you connect the two 2 ohm loads to the amp, it will see 1 ohm as it's load. If your amp can handle this, this is usually the lowest configuration capable by consumer stuff, (if you are not doing competition or some crazy thing), and few amps are rated for 1 ohm so it's not really recommended and may heat up or blow your amp. 4 ohm: Connect one negative to one positive terminal on one speaker. Drive the other open terminals with the amp. This places coils in series and results in an 8 ohm load per speaker. After connecting both speakers to the amp, the amp will see a 4 ohm load. In both cases, the rates power of the amp (at that load) will be divided equally between the speakers. Jun 12, 2009 - For dual 2 ohm speakers, the only loads you can achieve are .5 ohm (1/2 ohm), and 2 ohm. The connections are the same as above, and this results in: ...If coils for each speaker are wired in paralell, the results are 1 ohm per speaker, and after connection, the amp sees 1/2 an ohm. (.5 ohm) ...If coils are wired in series, the result is 4 ohms per speaker, and the amp will see 2 ohms after both are connected.

Wiring Speaker to amp


remove all speaker connections to your amp. MAke sure the inputs are driving all 4 channels, and that the built in crossovers on the amp are all set to full range. Conect your full range speaker to each output channel one at a time and verify there is oputput on all 4 channels. If all is ok, then connect your rear speakers to the front(a) outputs of your 4 channel amp, and then use the second 2 channels (rear or B) bridged to drive the sub. Re-configure the crossovers for highpass for front (to drive your rear speakers) and lowpass for sub. This is the proper way to connect a 4 channel amp with a sup whle driving 2 full range speakers.

Which capacitor or resister we use when connecting tweeter with subwoofer, or what do we connect to the subwoofer to get more bass ?


Hello johnwisam,

When using component speakers, it is normal to connect the head unit or amp outputs directly to the woofers and use a "high-pass" filter to the tweeters. Most component speakers sold as a set will include the correct filter along with wiring diagrams. The12volt.com web site shows examples of passive crossovers here.

Amps usually include built-in filters and a means of setting crossover frequencies according to the speakers attached. If the amp is connected to full-range speakers, it is set to "Full" or "BP". When used to drive subwoofer(s) only, the setting is most often "low-pass".

Most stock radios and aftermarket head units are relatively low power and just do not produce enough power output to drive subwoofers adequately. It takes more watts to move the larger cones and that usually means a separate amplifier.

Hope this helps.

Amplifier loads


Hello ronnieyannon,
A single 4 ohm speaker wired to each channel, like you have them wired, presents a 4 ohm load. And it appears that you have them connected properly. The 401s is only stable to 4 ohms when bridged, so if you were to parallel the 2 4 ohm subs in bridged mode, the load would be 2 ohms and the amp would most likely overheat and go into protection.

I'd wire them the way you have them wired.

Each channel of the amp outputs only 100 watts into 4 ohms. That is adequate for regular full-range speakers, component speakers, mid-range drivers, and even some small subs. But it is a little low on power for most subwoofer applications.

Hope this helps.

Pioneer DEH-P3000IB... Hook up RCA cables to 2, 2 channel amps for front and rear control. Supposed to be able to set rear to either rear full or sub... can't find how and all I'm getting is sub response.


Here are the directions according to the manual:

1 Use MULTI-CONTROL to select
SW CONTROL.
2 Press MULTI-CONTROL to display the
setting mode.
# Press BACK to return to the previous display.
3 Press MULTI-CONTROL to select the segment
you wish to set.
Press MULTI-CONTROL repeatedly to switch
the segment in the following order:
REAR SP (rear speaker setting)—PREOUT
(RCA output setting)
4 Use MULTI-CONTROL to select the desired
setting.
Turn to change the setting.
When REAR SP (rear speaker setting) is selected.
REAR SP:SUB W(subwoofer)—REAR SP:FULL
(full-range speaker)
When PREOUT (RCA output setting) is selected.
PREOUT:SUB W (subwoofer)—PREOUT:REAR
(full-range speaker)
# When no subwoofer is connected to the rear
output, select REAR SP:FULL.

Hope this helps.

SOUND Q SERIES
DUAL 6-OHM CONFIGURATION
Accommodating the rising trend of triple-subwoofer applications, Audiobahn’s Sound Q subwoofers come in dual 6-ohm configurations. This allows three Sound Q subwoofers to be wired in a 1- or 4-ohm operation. You now have the option to use a wider range of amplifiers to fit the needs of your specific application.

MULTI-CONNECT LUG LOCK TERMINALS
Audiobahn’s patented Multi-Connect Lug Lock Terminals offer increased versatility in wiring multiple subwoofers to an amplifier or to another voice coil. Multi-connect terminals allow you to use single wire connections in each terminal rather than combining multiple wires into one terminal. This feature allows you to use a full 8-gauge wire in each terminal.

COMMON FEATURES
Dual 6 Ohm VOICE COIL
Multi-connect Lug Lock Terminals

The Link below should answer all your questions.
Also remember to try to keep the lengths of the jumpers the same. I would make all the connections inside the box then use the teminal block of the box to connect to the amp.
Keep in mind that you can only get 1 Ohm if you use 3 woofers.
Your configuration allows for 1.5 Ohm
