How do I hook up subwoofer sony cxs-gt08hp


NO!!NO!!NO!! Dont hook up just a sub to rca outputs. they run at around 2-3 volts and maybe 1 watt. the difference in the settings is for a sub amp(sub) or a amp for mids and highs (amp). the only way you will not need to run an amplifier is if you get a powered subwoofer, as these already have an amp built in.

Can i wire one speaker to the other speaker inside the box so that i only have one positive and one negative cable wire coming out out of the box and to the amp


Hello... I can help you with this question. Yes it is possible to do this, but you will have to use a 2 ohm stable mono block amplifier in order to do this. By connecting both positives together and both negatives together, you will be running a 2 ohm load. So if your amp is a monoblock amp, connections will be simple as tieing all the positives together and the negatives together and just hook to the amp. If you are using a 2 channel amplifier that is bridgeable, then you will need to series the subwoofers to an 8 ohm load and then bridge the amplifier to 1 channel. The way you series the subwoofers is take the positive wire in the box and hook to the positive on subwoofer #1. Take the negative wire in the box and hook to the negative on subwoofer #2. Then take a piece of wire and hook the negative from subwoofer #1 to the positive connector on subwoofer #2. Then hook the wires to the amplifier. To bridge the amplifier (if it is a 2 channel bridgeable) would be to use the left positive and the right negative, but check the amplifier for markings to confirm this. If you have any other questions, feel free to let me know and I will help you out! Hope this helps!!

I just picked up a 12" type r in a box with a alpine m 350 how do I know what kind of type R I have without taking it out of the box?? and how do i hook it up to this amp??


Not to insult you in any way but u need to know how to wire into car's electrical system at the battery then to a fuse then to the amp and then output the signal from the deck to the amp.. finally to the subwoofer. you need to hook up 12V constant battery power , then remote from the deck ,ground wire from amp to chasis for power.. then wire to sub.

I have a 12" subwoofer and i was wanting to know how to hook it up with out a amp or if you can even do that


They need alot of power to get sound out of them. If you hooked it up straight to the radio without an amp, you would barely hear it.

Need to hook up to a 4000 watt amp


Why would you hook up 4000 watt amp to a speaker that has only 1000 watts. Try a 800 watt amp instead unless you just dont want the spealers.

Subwoofer out problem


Thats an installation error. I'm almost 100% sure whoever hooked up your amplifier hooked the amp turn on to your power antenna wire. If there is no amp turn on wire, the accessory wire will do.

Need to know


I'm assuming that you have an amp that you are installing these to. Its always tricky installing subs of different impedances. Do you have the model number of the amp that you are hooking them up to.
Most likely if you have a 2 channel amp, you would connect one sub to each channel as most amps can handle a 2ohm load in stereo, but don't bridge the amp with these two subwoofers without specific instruction from someone with experience as you will most likely overlad the amp. If you can be more specific with your set-up I'd be able to assist you more.
