Also called speaker level inputs, an input on an amplifier specifically designed for higher voltage and lower impedance signals, typically between 1.2 to 12 volts and 4 to 8 ohms, as found on the outputs of low powered speaker connections. Hi-level inputs are commonly used as an easy and convenient upgrade path to connect factory-installed head units to after-market amplifiers.
high level inputs are less subjected to interference and can travel further without signal loss.
Factory radios do not have dedicated outputs for amplifiers (preamp outputs). So you'll want an amplifier with speaker-level (often called high-level) inputs; these inputs enable you to tap into the factory speaker wires for a signal flow.
They're called high-level inputs because the voltage level is significantly higher than with a standard preamp output connection. These inputs convert the high voltage to one the amplifier can handle. Once connected, you'll hear clean, well-defined sound (including the lyrics to your favorite song).
Speaker-level inputs are a standard of many two- and four-channel, and mono subwoofer amplifiers.
All the power wires no the amp will be ran the same with the exception of the remote turn on wire. +12v constant will still go to the battery(properly fused with 12" of the battery!), and the ground will still go to the chassis. You can hook the remote turn on to the +12v ignition wire behind the radio, or the equivilent fuse in the fuse box. I would not recomend hooking it up to the pwr ant wire on the stock deck as it often goes off when the radio is off, or cd is playing.

As I said, most cars have no issues with any of this, but cars with "PREMIUM SOUND" systems often do not mesh well with aftermarket equipment. Fords JBL or chrystlers infinity (And bose in darn near anything!) are often cause issues. Sometimes you can easily bypass this system(Ford), sometimes you have little choice but to rip it all out and start fresh(Bose). I can walk you through the scenarios for most makes and models, but certainly do not have the time or patience to give every one. Hit me up on the forum and I will be happy to help you further....

Can I use a JX-S900 Y/C separated I/O to run two subwoofers out of same reciever??


Yes, on two conditions:

1) the JX-S900 needs to be a proper matrix switcher. It has to have the ability to route 1 input to more than one output.

2) the sub signals need to be low level RCA/phono, and not high level speaker wire connections. That's not just about the type of connector. It's about the signal going through those wires. A low level RCA/phono sub connection conducts a maximum 0.7 Volt. A speaker wire connection can transmit 30 Volts! If you put 30 Volts in to a line level switching device such as the JX0S900 you'll fry it.

Provided that the above two criteriia are both met, then yes it will work.

  • Connect the AV receiver's sub out to Source 1 - white RCA phono.

  • Connect the two subs mono LFE Left input (white RCA) or the single black RCA/phono inputs to the JVC's outputs 1 and 2 - white RCA/phono.

  • Set the source routing: input 1 goes to output 1 and 2

On my Sansui sw-100 sub, I have 2 speakers connected to the high level output, that dont operate


Yes in order to have audio going to your spare speakers from the sub .You would need to use the hi level inputs comming from the reciever outputs connected to these hi level inputs..The sub will then crossover the audio to their proper outputs..Hope this helps you

How it can be connected to a stereo amp


hi,
if ur amplifier have a pre out, then u can connect that to ur L/R input of ur sub woofer.

if not the only way is, connect ur amplifiers speaker output to sub woofers speaker input and then connect ur speaker to sub woofer speaker output terminal. remember don't inter change positive and negative wires.

if ur amplifier have speaker A,B connection then it is very easy. connect the speaker A to ur left and right speaker. then connect speaker B to ur sub woofer's left and right speaker input. be sure to make that speaker A and B switch is in on position. the power on both and check it. ( use good quality speaker cable to connect the sub woofer)

your sub woofer is designed to work , both at low level and high level input.
ok

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 use the high level speaker inputs on this snell QBx sub.


Most likely, you simply connect the speaker wires to the high level inputs, along with the cable from your amp.

Given that Snell's are high-end speakers, I would recommend that you contact their tech support for your question. They have a specific email address for technical questions on their Support Page.

Can you please tell me how to connect my kef psw


If your amp has a "sub out" jack, that's the best way to hook up this sub. You'll just need a single RCA (also called "phono") cable. Connect it to the Left input on the sub, which should also be marked as "mono"

If your amp just has speaker-level outputs, then connect the left and right main speakers from your amp to the sub's high-level inputs, and then run wires from the sub's high-level outputs to your speakers.

If you're running a surround-sound setup, use the front-left and front-right speakers for this hookup.


If this helps, be sure to hit the "thumbs-up" button for me!
If not, post back with the "Add comment" and I'll do my best to answer any questions you've got.

Bose Lifestyle 50 - connection to a non-bose amplifier


The 2 system are completely different your is low level input and its is having only 2 input L and R when those signal they get inside your sub it process through an DSP ( Digital Signal Processor ) and become 5 output to yours satellite cube speakers
The AM6 or 10 are high level input connected direct to any output of any AMP from those signal they convert down to low frequency for sub woofer

Connect powered subwoofer


  • If your receiver has a dedicated subwoofer line level output, we recommend connecting your subwoofer to this jack. Most receivers will have just one (mono) subwoofer output, while quite a few subs require two inputs. You can use an RCA "Y" adapter cord , which is a cable with one female RCA jack at one end, and two male RCA plugs at the other. Some receivers require menu settings (such as "sub-on" or "front speakers-small") that must be made before the sub output will be active.
