How to run the speaker wires to connect to the subwoofer? and does a sub woofer burn if you do not put the right ammount of watts to it for example having an kicker l7 connected to a three houndred watt 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

Try this wire diagram for speaker connection

no problem with replacing all speakers with ones that are compatable wth you new amp .. and that means the the speaker impedance has to be wtihin the range of what the amp can drive (like 4 ohm, 8 ohm, 16 ohm) .... the subwoofer needs inputs from both left and right channels .. it also needs its own amplifier and low pass filter .. this all may be built into your after market amplifier .. if so you will have an output marked sub (that will directly drive the subwoofer) .. or you may have a low level outdput marked sub that goes to your subwoofer amplifier if it has one .. .. sometimes the woofer has its own built in amplifier and filter .. it then just needs power and inputs from each channel .. since you are running 500 watt speakers, they likely already have a subwoofer component .. (speakers that extend down to 20 hz or lower .) if so, you may not need an additional sub-woofer .. just make sure all the speakers are phased correctly .. (wired to work together not fighting each other ..) .... an amplifier capable of driving 500 watt speakers can draw peak currents that are very high .. so power wiring would have to be very heavy and preferably go directly to the battery with an inline fuse right at the battery ..

Your receiver should have an RCA connector on the back panel that will be marked "sub woofer" or "LFE out". That connects to your sub woofer with a standard RCA type cable. Also, some powered subs have left and right speaker level inputs and outputs in which you would indeed run the sub woofer through the speaker outputs. The down side of that type of connection is that the line level converter inside the sub woofer will take a slight amount of your receiver's output power, although that is rarely detectable. Also, if you have a Dolby Digital receiver, using this connection method will take away systems ability to accurately control the low frequency effects of a soundtrack.

Good Luck,

Get a powered sub-woofer that has speaker level inputs, then run your front speaker wires into the sub-woofers speaker level input and then run a set of speaker wires from the sub-woofers speaker wire output to your front speakers. This is a common way to use a sub-woofer with a receiver that doesn't have a sub-woofer output.

Most powered sub-woofers have these connections, just check it out first before you buy one. They look like speaker jacks on the back of the receiver.

Let me know if you have any other questions.

First check the speaker wire from the amp to the sub, see if it's connected right. Second check the rca cables that goes from your amp to the back of the deck. I f both wires are still connected fine try to replace the rca cables. If it still doesn't work the rear out put at the back of your deck, where the rca's are connected are bad. FYI deck is bad.

In general, there are two ways to hook up your sub-woofer. First using the high level outputs from your receiver ( speaker output from the front R & L speaker terminals ) run a set of wires from the outputs to the speaker inputs on the sub-woofer, you do this in concert with the speaker wires going to the front R & L speakers which you then attach to the R & L speaker outputs on the sub woofer amp. Note that the sub woofer doesn't power your front speakers, the connections from the sub amp are just a pass through connection where the signal needed by the sub is parasitically taken from the inputs.
Second is via a low level output from your receiver / amp to the low level input on your sub amp. This is normally done via a RCA type of patch cable and connected to the sub woofer RCA jack on the rear of the source receiver or amp, Next run the patch cord to the sub amp an into the RCA jack input. IF you have a right and left input, use the Right input.

Sounds like you have burnt out something (as you probably already know LOL) but maybe you just over heated some wires that couldn't take the Amperage. If this is the case, you MUST find out:

Why there was so much Amperage there at the time
Why didn't the Fuse blow? (perhaps too high an Amperage fuse for the Unit?) and
Why could your unit not handle the Power? (perhaps not Rated for that Power Output?).

Note: Watts and Amperage are not Musical terms, they are Electrical terms. So an Amplifier Increases the output Current to a maximum level designated in various ways as PMP (common but misleading) RMS (the International Standard) and DIN (the mainly European standard). The receiving unit (in this case your sub woofer is designed to handle a maximum level of Current input and this is usually desribed (again misleadingly) as simply Wattage. The common factor here is that both your Amplifier and Sub woofer are probably using the PMP rating.

If this is the case then you can easily determine if the 2 units are compatible using their "Wattages". For instance, a 275 Watt amplifier is too much at HIGH outputs (volume) for a set of speakers Rated at 160 Watts (they will "blow") but will work fine at Lower volumes because the Amp is putting out less Power at Lower volumes and is therefore probably below the Speakers Maximum input range.

Conversely, it is OK if the speakers are Rated for higher inputs than your Amplifier can put out. For example, a 175 Watt amplifier is fine with speakers Rated for 240 Watts because it can never produce enough power to "blow" the speakers.

Just putting in heavier wires will almost certainly bow up the sub woofer if the initial problem is not solved.

Take it to a HI FI shop and get them to look at it. If they simply say "Can't repair these, buy this one", try another shop.

Sorry about the lecture.

Good luck.

its all about impedance matching...did you check to see that the new yamahas would drive from the system, before installing them? sounds like you will need to possibly add a matching transformer or other device on this one.

check all speakers wires andcheck test mode. every thing ok, may be input wiring problem ,check every thing after that internalcircuit may be problem..
