RCA Outs are very low power signal connectors. They would have a hard time running a pair of headphones.

What you need is a Power Amp that the RCA's plug into and your subs Connect to.
You need an Amp (Amplifier) that powers a similar number of Watts to what your Subs Capacity is. (ie; your subs have a ratting of 100W (Watts), then you need an amplifier with 100W per channel; that's a 200W amp for a two way (Speaker) amp, or a 400W rating for an amp with 4 channels (4 Speaker connectors)
You can run a lower power amp on your subs, and use ony a portion of your speakers capacity; but if you get an amp that supplies more wattage than your speakers capacity, then you'll blow your speakers, their performance will deteriorate slowly. eventually they will not be able to generate a clear reproduction, Speakers are irrepairable.

Sorry for the long explanation.
This is something you wan't to do right, the first time.

Cheers,
Richard.

Have jvc rx-2020v receiver with mono rca out for sub and trying to hook it up with polk audio rm 1000 w sub woofer with +/- terminals for both left ane right channels plus blue terminal(?). How to?


Your Polk Audio subwoofer is a passive sub and your JVC mono output is for connection to a powered sub. If the JVC does not have an amplified output for a passive sub, you'll either need to get an amplified sub, a different receiver, or buy a dedicated mono subwoofer amplifier.

How do I hook up passive subs to my board


Sub outs needs an active speaker.

An active speaker have a built in amplifier and preamplifier.

For a passive speaker it needs an amplifier.

Hi, I have the Kenwood Subwoofer KS-201-HT, my question is how do I connect it to my receiver?


usually subs have outputs 4 ur monitors however if ur sub is active @ ur monitors are passive then you need 2 connect sub 2 ur tape loop with rca connections,usually you use the send signal from ur reciever which would norm connect to ur tape input , if the sub is passive then u connect direct to speaker output on amp then monitors to the sat connections on sub

How do i connect my pv2600amp to my peavey subs and top speakers, i have the leads but what do i do?


Line outs Left and Right from mixer to power amp Left and Right inputs,
Power amp outs to Subs(if they have passive crossovers built in check specs on subs).
From Subs then to Main spkrs. Make sure power amp is set in stereo mode using this way.

Alternative: You will need at least a 2-way stereo crossover unit inline after mixer and before power amps if the subs don't have a built in passive crossover. Most of them do have passive crossovers in the subs these days. Then separate amps or one channel would drive the subs and the other the main speakers. True stereo would require at least a 2 way crossover and two stereo power amps if hooking them up this way.

There is another option as is common with many sub setups. Send the signal to the mains using L/R outputs from mixer and a separate Mono output to the subs only. Putting only bass/kick and low frequency outputs in this send would help too.

Hey is ther any why i can run six Speakers off this head unit + an amp and sub system?


The head unit will drive four speakers, 2 front ,2 rear.
Best way to add two more speakers and a sub is to get a 4 channel amp. Hook it up to the RCA jacks from your head unit. Bridge two channels of the amp to drive your sub, and use the other two channels of the amp to drive the extra two speakers. Just make sure whatever amp you get it's bridgeable.

Subwoofer.......


Please check your model number, I can not find it on the JVC service website.

This is a powered sub-woofer I think. You need to have a thick black cord that connects the sub to the head unit. Then the satellite speakers get connected to the speaker jacks on the sub-woofer box. The sub-woofer should also be plugged into an A/C outlet on the wall.

The speaker outputs are labeled right there where you connect the speaker wires. You should see a red and black connector for each speaker and they are labeled "front right" "front left" "center" "rear right" "rear left".

If you do not have the thick black cord you need to connect the head unit with the sub-woofer, you can not use this system.

If you look at the head unit and give me the model number on it, I may be able to find the part you need. But I must have a good model number to work with, preferably from the head unit.

Is it a good idea


Hi,

Based on your description and on the idea of a single amp, then your plan of hooking up both the subwoofers in series (to get 8 ohms) would be the safest as against running the subs in parallel (2 ohms). This way the sub amp would not be overly loaded, you can compensate the slight loss in power by strategically positioning the 2 subs. A friendly reminder, pls observe polarity when hooking the sub speakers.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Yes you can use the speaker output in conjuction with the rca pre-outs...but depending on the wattage of the amp, there may be a big difference between the loudness of the front speakers over the rear speakers. If you have a 4 channel amp you can put the rear speakers on the amp also and lower the input gain for the rear speaker. Or if you have a 2 channel amp, you could use a passive crossover to filter out some of the bass to the rear speakers since they are smaller, this would help prevent over-driving them...as it is normally too much bass that distorts and blows a speaker. I'm not sure what you are asking about the hi-rear preouts vs the mid front pre-outs. If you decide to use the amp for the fronts you should be able to connect the amp from the front preouts of the deck. Hope this helps.

About technice sa-dx930


The one plug on the back of the receiver is an rca-type plug and is designed to be connected to a powered sub, which would also have an rca-type input. Even if you connected it, this output carries a line level signal and is not powerful enough to drive a speaker. If your sub has 2 connectors (same as a normal speaker) then you have an unpowered or passive subwoofer. You would either need a powered sub, or to use an external amplifier of some sort...then the sub output from your current receiver would go into the external amp...and the amp connected to the passive sub.
Hope this helps.
