Question about Car Audio & Video

Open Question

I have an audiopipe line output converter that is quite low end. it has left and right speaker inputs, a ground, and rca outputs in a compact unit. I hooked it up to my 2008 grand prix with a monsoon system to get rca outputs for my two 10 inch subs and i noticed that i am getting poor sound quality with my subs. it is hooked up to the power leading from the factory amp to the subwoofer speakers on the rear deck. i have played around attempting to tune the system as a whole and am getting nowhere near the bass i want. (i had the same subs and amp hooked up in my old car, but using rca cables from the aftermarket stereo, this had 100 times more bass then i am getting now.) I can not remove the stereo and put an aftermarket stereo in due to the loss of functionality (computer functions, etc...) So my question is, do i need to purchase a higher quality loc? one that caught my eye is the AudioControl LC2 which is supposed to have accubass to provide good bass output and a remote wire output to name a few http://www.crutchfield.com/p_161LC2I/Audiocontrol-LC2i.html?tp=2001&tab=detailed_info. Or is there a different way for me to hook up the LOC that i already have installed? any advice would be great. Thank you, Max Sauer

SOURCE: No power output

Set the meter to AC volts and measure the AC voltage on the RCA cables where they plug into the amplifier. The black meter leat will go on the shield ground of the RCA cable. The red lead on the center conductor. You may have to turn the volume up to get a reading on the meter. At high volume, you should read at least one volt but the actual voltage will vary due to the audio signal. If you get no voltage on the RCAs, measure the AC voltage on the input to the LOC. Let me know what you find.

SOURCE: Subwoofer Connection: Speaker wire to Mono RCA

The easiest solution to use your subwoofer is to buy an amp for it. Any old stereo receiver from a garage sale will probably do just fine.

  1. Connect the mono RCA subwoofer output from your Sony with a 1xRCA-to-2xRCA splitter to both the left and right input of the cheap reciever's tape or aux input
  2. connect both speaker outputs of the cheap reciever to the speaker input on your subwoofer. make sure both black (-) outputs on the reciever connect to the black input on the sub, and the red outputs (+) on the reciever are both connected to the red input on the subwoofer.
  3. make sure the cheap receiver's volume is all the way down. turn your Sony up to about the loudest you'll listen to it. turn up the subwoofer amp until it's loud enough to sound good.
  4. leave the subwoofer amp alone, the Sony volume will all you ever need to touch from now on.

You can even now turn off your subwoofer / adjust the volume easily now!

SOURCE: Install two 10" subwoofers in a 2002 grand am monsoon.

The only way to Correctly do this is to Run an External Amp for your Subs. If you continuously run the Subs off of the Factory Amp It will Ruin the Subs and the Amp Eventually. This way you can still Connect the Rear speakers as they need to be. Please Rate my solution, I need all the Help that I can Get! Thanks!

What you have been told is correct, these proprietary systems are great for the manufacturer, but when they start to have issues (and they will) they leave you 2 options: pay through the nose to stay original or replace the amps with new ones....the upside of this is aftermarket amps are soooo mugh better than stock that it is lauhgable.

Your TV has a pair of analog RCA Audio Outputs on the back of the set. They are the red and white, female, round outputs and should be labelled as Audio Out. If you have a surround receiver or stereo that accepts this type of input (most do), then you would purchase a stereo RCA audio cable that has the red and white male ends on both ends of the cable and plug them in to the appropriate stereo RCA left and right channel audio inputs on your receiver and the aforementioned outputs on your TV. The same is true if you have a pair of self-powered computer speakers (or similar). If your external speakers or audio systems don't have the RCA inputs, you may need to get an adapter to convert the RCA output to stereo mini-jack (or similar) to match the appropriate input on your external speakers. Does that make sense?

Another conundrum


To check for yourself, get an Ohmmeter and see if the outers of the amplifiers RCAs are connected to the ground or each other. If so then it cannot take speaker signals directly.
I suspect the 'High Level' the manual speaks of are the 4volt auxilliary audio signals that can be found on some newer head units, not speaker signals.
Speaker level signals from a bridge amp CAN be used on grounded RCA inputs if the signal is first passed through a simple decoupler and attenuator.

Tip

Car amplifier troubleshooting


No output:
  • Confirm that all terminal strip connections are firmly connected.
  • Check in-line and built-in fuses. Both +12V and RMT terminals must have +12V to chassis ground.
  • Confirm that signal source ( Car Radio/Deck, EQ, X-over etc) is connected and is supplying output signal.
To confirm that Amplifier is working, connect an RCA patch card to LEFT& RIGHT low-level inputs of Amplifier only ( Do not connect the other end of the patch card).Briefly tap the center pin of each ( disconnected) RCA plug on the other (disconnected) end with your finger. This should produce a noise (feedback) in the speakers.

If this tip in anyway helped you please do not forget to rate it, thanks.

I have a stock stereo and two subs with an amp in the trunk. Also two alpine speakers in the rear. Whenever I turn my balance to the left my subs don't play. What's wrong?


Hello.... I am sorry to hear you are having problems. The reason for this is that since you have a stock stereo, the shop (or person) whom installed the amp and subs used a line out converter. What this part does is allows the connection of RCA cables to the factory head unit. Almost all bass signals are always in stereo, so since you were only hooking an amplifier for just subs, you can actually just connect to just one of the rear speakers instead of connecting to the right and left. Just makes the install a little quicker. There is nothing wrong with this as I usually do the same thing in our shop. However, if you are going to be using the balance control, then you will need to go back to the shop and have them hook the converter up in stereo (to both rear speakers). Hope this helps!

I have a Boston Acoustics VR-500 Subwoofer with a problem. As soon as anything is plugged into the line level RCA jacks, the subwoofer produces a loud buzz/hum. I have tried connecting it to the subwoofer...


I'm thinking you have an open shield ground on the RCA input side. Connecting speaker inputs possibly restores the ground. Try connecting the high level inputs then disconnect the remote end of the cables (floating the grounds).

Then get out an ohmmeter and find that open circuitor or bad solder joint between RCA ground and real ground in the speaker's amplifier. Or.... if speaker ground kills the hum and you want to use RCA Line Level input to the sub, just connect one minus speaker output on your source amp to one minus on the sub's amp.

What wires do I hook up to the high level in plug that came with my dual xp2100 2 channel amp


First, know that you need either high level input or low level input, but not both. Low level input is preferred (RCA cables). If you must use high level input because your head unit doesn't have RCA jacks, you connect the speaker outputs from the head unit to the high level input of your amp. The high level input plug probably has a black wire, this is "signal reference ground". A pair of grey wires which are right positive (grey) and right negative (grey with black stripe). And a pair of white wires, left positive (white) and left negative (white with black stripe).

When I hook up the speakers in the back to the left and right side for the in and out, do I connect the front or rear speakers. do the speakers connect to the subwoofer first then to my receiver or the...


I was trying to find an owner's manual or picture of the rear panel of the sub, but had no luck. The subwoofer is a powered type - or "active" speaker. This means it has a built in amplifier. These active subs usually provide for one or both "low level" and "high level" inputs. Low level signals are usually carried by shielded coaxial cables and have RCA type plugs on the end. The low level is also called "line level". This is an un-amplified signal that might be heard on cheap earphones - but that's about it. It is similar to the output of a tape deck, DVD or phonograph. These signals require an amplifier to be heard. If you have a sub woofer output on your receiver or amplifier, you could run a patch cable between the low level input on the subwoofer and the subwoofer output of the amp or receiver. You receiver or amp may call this output "low frequency effects" or similar. The front and rear speakers would then connect directly to the receiver or amp's corresponding connections.

If you lack low level outputs on the amp or subwoofer, you'll need to run speaker wires from the amplifier or receiver's front left and right speaker output terminals to the subwoofer's high level input terminals. High level signals are speaker connections or amplified signals. These are typically connections that accept bare wire connections. The front speakers would then connect to the subwoofer's front left and right speaker output terminals. The rear speakers connect to the amplifier.

I hope this helps - and good luck!

Where are the amps and how do i by pass them for the stereo


The amps are located inside the radio. Most in-dash receivers that provide for "pre-amp outputs" also called "low level outputs" do so by providing female RCA type jacks. These are often found at the end of a short (4 - 6 inch) cable and are usually color coded red & white or red & black (some receivers provide a yellow RCA jack for video in / out, too). To use these RCA audio jacks, you need to realize that one jack is for the left channel source and the other is for the right channel source for a stereo signal. You will have to connect a compatible plug and cable of enough length to extend to a remote amplifier's RCA input jacks. The vehicle's speakers would also need to be connected directly to the same amplifier's output terminals. Using the two audio (left and right) RCA jacks will only allow the radio to control balance of the left and right audio, no fader (front and rear) control is possible. To get fader control, you'd have to either have a radio with four RCA low level output jacks (front L & R *and* rear L & R), or use the radio's speaker (or high level output) wires and connect them to the amplifier's speaker (or high level) input terminals.

All unused receiver wires should be terminated in a wirenut or securely wrapped in electrical tape to prevent accidental contact with grounded metal or other wires behind the dash.

I hope this helps!

Hello herb31,

It sounds like there is a difference in the signal levels on the inputs to the amps. You did not specify what the RCA's are connected to on the head unit side. If they are connected to a stereo pair of preamp outputs, you may be able to solve the problem by using only the channel with the higher signal and use an RCA "Y" adapter to split it to both amps. If they are connected to a dedicated subwoofer output on the head unit, make sure that the head unit is set for "subwoofer". Some less expensive head units, I know JVC in particular, has only 1 set of line outputs and requires you to go into their "PSM" (Preferred Setting Mode) to set the line output mode and if you select "subwoofer", then allows you to select the low pass frequency.

If you are converting speaker-level outputs through a "line out converter", check both the input and output levels.

Also, if you are splitting an output from the head unit, you still need to connect 2 RCA's to the amp inputs. The signal will be properly split if you use a 1-female to 2-male "Y" adapter. To feed the same signal to both amps, you would need 3 "Y" adapters. Feed the output signal to the female end of the first "Y", and plug the male ends into the other 2 "Y" adapters. Then, the 4 plugs you have left on the ends go into your amp inputs.

Hope this helps.

Hi, Jensen is under different ownership from when your amp was made, so it's unlikely that you'll find a replacement plug for the high-level input. A high-low converter is also called a line-out converter. It's a device that connects to the speaker wires and changes the signal to a low-level RCA connection. This allows you to use the amp's RCA plugs with your speaker wiring (through RCA signal cables). A line-out converter should be available any place that sells car audio accessories.
