Sounds like you need another amp, if the amp has a speaker already connected to each channel, you have no open channel to connect a sub-woofer.
Some years ago I seen an amplifier that was designed to use 3 speakers on 2 channels. what they did was had a speaker on each channel and then they bridged the 3rd speaker across it. That amplifier was designed for this configuration, unless you have an amplifier like that you should not try it. It may result in smoke from the amp.

I need a wiring diagram from car stereo to 2 x 6 " x 9 " and a sub woofer please


You can connect the two 6x9 speakers to the two individual left and right outputs of the car stereo.
Connect each of the left and right channel with the correct polarity . Now the Sub-woofer requires an amplifier to be connected separately and so you need to use the car stereo to be linked to a sub woofer amp which powers the sub woofer.

What is the best way to wire four 6" 55 watt


My advice would be to connect the front speakers and the sub woofer to the amplifier and run the remaining rear 2 speakers from the headunit. This way you dont stress the amplifier to run on two different loads at the same time and still maintane control over your system. Bridge your sub woofer on chanel 3&4 and do not forget to set the LPF for chanel 3&4. If your speakers are not components in the front set the HPF on chanel 1&2 to roughly 60 to 80 Htz.

i have found the specs to your amp. 1. Amplifier connections: Lets make things simple. As we look at the amplifier speaker connections, we will number the outputs 1 2 3 4 from left to right for the top connections and again 5 6 7 8 from left to right for the bottom connections. 1 should be connected to a positive (RED) (+) on sub woofer A on voice coil (a) 4 should be connected to a negative (BLACK) (-) on sub woofer A on voice coil (b) Now using a small piece of cable, connect negative of voice coil (a) to positive of voice coil (b) Follow the same procedure for the other sub woofer using 5 and 8 as 1 and 4 This configuration should make the amp run at 4 OHM BRIDGED x 2. i hope this helps. dreamsystems

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

If you are getting power to the amp, try this....Find a small speaker, unhook your sub and wire speaker to amp. Turn on your system at a low volume....If the other speaker is playing through amp, then your sub is shot.....If the small speaker doesnt work, then its either your channel is gone on the amp or the rcas have quit off off your head unit.

Hi,just bought a 6x9 jbl gto937 speakers for my car,each speaker is 100watt rms and 300 max .Can anybody advice on what amplifier should i get for them?I know i can run them without any amp but think they...


Pyramid makes the PB series of amps. I have one that's driving a Sub.
The PB 700 puts out rms 60watts x 2 @ 2ohms, which gives you some "headroom" for your speakers. You don't want to over drive speakers with , for example, a 1000 watts for 100 watt speakers, because that's a good way to blow your speakers.
There are many brands and models of amps that will fit your speakers. Just make sure the amp will drive 2ohm speakers, since your jbl's are rated at 2ohm impedance.
You may want to consider adding a Sub woofer to your setup. A single Sub would fill in the low end very nicely. If you got a 4 channel amp, then two channels will drive your jbl's, and you can bridge the other two channels to drive the Sub. That would be a kick'n sound!
Just make sure the amp is bridgeable
For example, the Pyramid PB 1200 is a 4 channel, bridgeable amp. This particular amp will drive the 2ohm jbl's, but you would want a 4 or 8 ohm Sub connected to the bridged channels.

Nice write-up.

http://www.sherwoodusa.com/pdf/RD-6500(English).pdf

On page 6 of the manual it states you should use a powered subwoofer and the unit provides a sub output on the rear panel for it. The message from the amp kicking out is that you're not going to get away with your workaround.

I would advise you to purchase a nice amplifier (2-channel bridgeable or single channel) for the subwoofer. That way you'd be sending only LFE signals and your receiver has provisions for adjusting its volume relative to the rest of the channels. I use a nice 5-channel Carver for my 3 subs and both Rear Surrounds.

On eBay I see what I would get if I were you - a Carver M-200T (120W x2; 300W bridged). I have one.

Sub woofer freq prob


Without hearing the noise, it's difficult to determine the exact cause. I've seen enclosures do this if the panels were not glued together well.

 

Try connecting the speaker to one channel at a time to see if one particular channel causes the problem.
