RCA cable use

Hello there this subwoofer has a built in crossover variable from 50hz to 150hz which means that any signal you feed it the sub it will ignore anything but bass anyway.

As for the connection it is made quite difficult if you don't already have an amplifier powering your other speakers, usually home cinema amplifiers have a low level pre out for subwoofers, for which you would just need a phono to phono cable.

However if it doesn't and you have any type of amplifier with at least 2 separate left and right speakers you can connect the wires from these into the subwoofer and it will output the bass from these 2 channels.

Another option is to use a mono to stereo (2 to 1) phono cable where the 2 connectors at one end connect to a tape or record output on your amplifier and the single phono at the other connects to the subwoofer, the same would go if you have a red & white phono (RCA) output on your TV you could also use this to power the sub, in the worst case scenario you could use a single to single phono or rca cable to connect one of the output channels (left or right) on your TV to the subwoofer however this would mean that the subwoofer would only output bass from either the left or right channel.

Hope this helps

Kind Regards

Hello missywarden,

According to the specifications, the amp is capable of "tri-mode" operation, that is, running normal speakers on the individual channels while also powering a subwoofer in bridged mode.

Your sub needs to be a minimum of 4ohms and should be relatively efficient. I'd look for a sub that has an RMS power range of from about 75 watts up to a maximum of 250 watts.

The sub connects to the leftmost speaker terminal (positive - right channel) and the rightmost speaker terminal (negative - left channel).

It's not going to be a really loud subwoofer. The power is 360 watts RMS which will be shared by the normal speakers and subwoofer.

Hope this helps.

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.

is the gain turned up on the amp, is the sub set to low frequency, maybe your head deck settings have bass/subwoofer off or bal set to front of the car.

Assuming you really want to have a working surround system you will need a separate stereo amplifier for the 901's to accomodate the need for the Active EQ. There is no way to separate your receiver's front L&R channel preamplifiers from their amplifiers.

I run a Carver AV-406 (5-channel amp) for my 901's in Front, 2 Subwoofers and the Rear Surround channel, with the Active EQ between the receiver and the 901's amp channels. My receiver controls everything and just drives the Center and Surrounds. You would probably just get a nice 2-channel amplier for the 901's. However, the TX-SR606 doesn't provide power for a Subwoofer, should you decide to get one, so you would need another amplifier channel for that, too. Therefore, you might look around for a powerful 3- or 4-channel amplifier so you could drive the Sub, too.

Modest amps would work but at very loud volumes may go into clipping, which is bad for any speaker. I'm using only 100W for mine and it has plenty of steam for the 901's.

For connection I would run a pair of RCA cables from the Front L&R Audio Line OUT to the Active EQ's Line IN; then the EQ';s Line OUT to a separate amp's Line IN. Attach the 901's to the new amp, run through the receiver's setup procedures for volume, etc and you're done.

Not what you might want to hear but 901's have special requirements. I've had mine for 25 years and have no regrets.

A seperate subwoofer channel on the amp could be used. Just run a single RCA channel from Sub OUT to one available channel IN on the amp and attach the subwoofer to it. Two would work, also. That's what I do. You could use a 1-2 RCA splitter to feed two avaailable channels on a 4-channel amp. The iterations are many. Have fun.

I have a VSX-36TX so this is how it's going to work...

This will depend on the amplifiers capabilities.

I will give 2 different scenarios.

#1 Stereo configuration

If the amplifier supports an RMS power output close to the RMS input power of the subwoofers then run the amplifier in stereo mode. For example 150 watts RMS X 4 channels driven at 20-20khz. (If you can provide a model # for the subs and the amp your looking at I can help you further with this decision.

Wiring for this is easy and simply involves matching the connectors for 2 of the channels (Front or Rear) to each of the subwoofers.

#2 Mono Bridged mode.

If the amplifier is lower power but mono bridgable you can bridge two Pairs of channels and power each of the subwoofers this way.

Generally speaking a 2 channel bridgable amplifier will be able to at least combine the wattage of each channel into a single monural channel and in many cases its actually higher.

So you would bridge the front 2 channels into a single bridged mode for one subwoofer. and then you could bridge the read 2 channels into another bridged mono channel for your other sub woofer.

For example if you had bridgable amplifier thats 50 watts RMS X 4 you coudl very likely (Generalization based on quality of amplifier) send 150 watts RMS to each subwoofer.

Again I would need to know what amp you're refering to to provide specific wiring instructions. Many Bridging amplifiers either have a single switch that will send them to bridged mode or you would use the positive + terminal from one channel and the negative - terminal from the other channel or a combination of both.

If your amplifier has what they call High level inputs (basically inputs on the amp that you run the speaker wires from your radio into), you can splice wires from where the connectors are on your rear speaker(s), still leaving the speaker hooked up, and use those as an input into the amp. If your amplifier does not have high level inputs, a convertor is available to turn an audio signal from your radio output speaker wires ( spliced in just as above, leaving the speaker hooked up), into an rca output jack. Or the best thing to do would be to buy another say 2-4 channel amp w/high level inputs and rca inputs and outputs, and run your rear speaker wires into the amp. Then you'll be able to run the rca cables out of that amp and into the sub amp, and you'll have the new amp to power your rear speakers or rears and fronts. That would be ideal. But, A convertor is your best bet. Got em at best buy, circuit city, etc. Hope this was helpful.
