Depending on the model, there are two ways to connect a subwoofer to an amplifier, receiver or processor. The best way is to connect the subwoofer to the SUB OUT or LFE output of a receiver, but some subwoofers can be connected to the speaker level outputs of the receiver or amplifier.
1. How to Connect a Subwoofer to the Subwoofer Output
The preferred method of connecting a subwoofer is through the LFE or Subwoofer output (SUB OUT) of a receiver. Almost all home theater receivers (or processors) and some stereo receivers have a subwoofer output. The LFE (Low Frequency Effects) is a special output for subwoofers and is often labeled 'SUBWOOFER' not LFE. 5.1 channel programs on DVD discs have a dedicated .1 channel output with bass-only content that is best reproduced by a subwoofer. Connect the output of the LFE or Subwoofer jack to the Line In jacks of the subwoofer using a single RCA cable (the two jacks on the left in the photo). A 'Y-Cable' may be necessary to connect the LFE output to both the left and right channels of the subwoofer.
2. How to Connect a Subwoofer to Speaker Level Outputs Some receivers and amplifiers do not have an LFE or Subwoofer output. In this case you can use the speaker outputs of the receiver to connect the subwoofer. Using speaker wire, connect the left and right channel speaker outputs of the receiver to the left and right channel speaker level inputs on the subwoofer (the speaker inputs on the right side of the photo). Using speaker wire, connect the left and right channel speaker outputs on the back of the subwoofer to the left and right channel front speakers.
If you have checked the speakers and wiring, the right channel has a audio driver or output problem, which explains the low volume, static, and distortion. A service technician will be required to fix the receiver so it will balance the left side.
Here is the link how the speakers are suppose to be connected.
You notice how they hook it up the left connections are your full range or hi frequency speakers and the switch is on for HPF (High pass Filter meaning only high frequency is being passed thru)
The right connections are connected to subs and the switch is on for LPF (Low pass Filter meaning only low frequency is being passed thru)
If you turn off these switches to off the its FULL RANGE all frequencies will pass thru.
The single output of the radio is probably for a subwoofer output but since your using the amp to power speakers too Its useless because your sending only low frequencies to the amp which will make any speakers connected to the amp sound horrible due too all the highs and mids will be filtered out.
STEP 1. 2 4ohm speakers depending where you put them Front or back. Hook these speakers up to the Radio's speaker wires coming out of the radio harness. You can also call them Hi level output wires FR & FL wires if positioning them in the Front. Hook them to the RL or RR if positioning them in the Back. What ever wires you dont use tape them SEPARATELY . DO NOT TAPE THEM TOGETHER and cause them to touch each other it will short out the radio and you will hear no sound.
STEP 2. Ok get 4 same length speaker wires and cut them long enough to go too the amp. Now these speaker wires will only send the FULL RANGE frequency signals to your amp. So note with a paper and pen how your connecting each speaker wire. I would tape one wire with black tape to remember this is the FR right, 2 tape FR left, 3 tape BK right, 4 tape Bk left. And I would make the copper thread of the wire positive and silver thread of the wire negative (very important so that your in phase and it will sound awesome) mixing up the positive and negatives will give you a tinney sound and it horrible to hear .
STEP 3 connect these 4 speaker wires to the High level out speaker wires coming out of the radio. The wires that are already connected to the 2 4ohm speakers go ahead and splice into them and the ones you didnt use connect to the remaining 2/4 speakers. REMEMBER OR NOTE THE CONNECTIONS cause you have to connect the right sequence and right polarity + & - to the HI Level input of the AMP. You will not use any RCA'S from the radio to the amp anymore. Since your radio dont have any Front & Rear output coming from the back of the radio. (YOU CANNOT USE BOTH RCA INPUT & HI LEVEL INPUT OF THE AMP ITS 1 or the other OR YOU WILL BURN OUT THE AMP AND DAMAGE THE RADIO)
STEP 4. Now connect your 2 6ohm speakers of your front left and back left together in parallel and your 2 6ohm speakers of your front right and back right together in parallel. Look at the diagram hook it on the left connections as in the picture of the front left speaker(but your connecting two 6ohms valued at 3ohms when in parallel and the amp can handle 2ohms so its safe) Do the same connection for your two right speakers as shown in the diagram of the Front right speaker. SWITCH THE HPF to OFF so that you get full range out of your speakers. Mid range is 70% of your music if you turn it ON you are only getting the high frequencies and it will sound awful.
STEP 5. This is the final connection Your 6 ohm sub is very bad for this amp. For example if you bridge it off of the last two channels the amp may double the power. If each channel is 100 watts and you connect the positive to one channels positive and connect the negative to the others channel negative(presuming its bridgeable) On a regular 4ohm sub it will be getting 200 Watts of power which is an average thump. Now you put a 6 ohm sub it will be weak and it will be getting around 130Watts. To make it worse if this 4 Channel amp is not bridgeable you can only connect it to 1 channel and the output will be around 70 WATTS causing distortion due to lack of power. If you still connect the sub be sure the switch is ON.
Good luck cause this the best connection you can do anything different and I'm sorry it will sound even worse. I am a master installer and have done this for 12 yrs. The higher the ohms the worse the sound gets cause less power. Thats why car speakers are 4ohms and home speakers are 6 ohms or higher cause they have a bigger amplifier to power and 120volts AC current. A car only has a 12Volt DC current powering the amp.
Hey ajn1n1 we need to fine where the tinnyness is coming from Lets do a test shall we,
hook up your voice matched polks to your front left and right speaker outputs on your amp to see how they sound as mains. if you hear tinny then its the speakers. sometimes speaker need to be broken in a bit.
hook up your main front left and right speakers to your rear outputs. if you hear the tinnyness then its the output of that channel on the amp or a setting. Newer amps let you change speaker sizes in the menu so that it can change over the crossover for that channel.
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.
Swap speakers over...check the balance isn't fully to the other channel...swap left/right phono cables over (if thats how your using it) other than that i would say is broke.
Easy way to check speaker cable/speaker... touch a small battery (like used in a remote) across speaker wires, you will hear and see the speaker cone move.
