How to hook up amp to speaker and sub - Crown XTi 2000 2-Channel Amplifier

you need speaker wire. you will hook one end to the negitive on the amp and one end to the black(negative) spot on the speaker. then hook one end of the other wire to the positive on the sub and the other end to the red(positive) spot on the speaker

dose the sub woofer hooked up to the t.v.

Depending on the PA FUBAR you have. The voice coil on those subs are DVC. Dual Voice Coil. You need to know a couple things. What kind of amp are you going to run on it. And what is the resistance (OHM) rating of each voice coil. MY two 12's are dual 4 ohm. Meaning that there are essentially 4 speakers to hook up. My amp currently is not 2 ohm stable in bridged. So what I did is run each speaker in parallel (red2red,black2black) then run to the box terminal. So now the dual 4 ohm voice coils are basically 2 ohm. I have 2 speakers. Now I hook the box up in series. To bring the now two 2 ohm speakers into one 4 ohm speaker. This is called series/parallel setup. My amp sees this box as 1 channel @ 4ohms. The downfall to this is the output of the amp is divided up into each speaker. So instead of sending all 1400 watts to one sub. I will send 700 to each sub. But here is a catch. even though each speaker is half the total wattage it will still be 3db louder. Meaning it will be as loud as 1 sub running 1400 watts. To conclude i need to know how many of those subs you are going to run on the amp.. And the model number of the amp so I can match up your wiring.

You will need an amplifier or 2 channel receiver. Hook the sub out rca jack to the rca inputs on this new amp or receiver and hook the speaker terminals on sub to speaker terminals on same amp or receiver. Your Yamaha receiver doesn't have any power for a passive sub.Just pick up any old fairly high powered receiver for fifty dollars and you're good to go.I use old dolby pro logic receivers as they are a dime a dozen today. Good luck.

depending on how many channels the amp is, you may not be able to hook everything up to it.

usually you have a separate amp for subs. 4 channel amp for the speakers in the car, and a mono amp for the subs.

To hook them all up to the same amp you would need an amp with 5 channels. It wouldn't work out right.

If you have a mono amp its only for subs.

If you have a 2 channel you can either hook it up to the rear speakers or bridge them to mono to run the subs.


you need a channel per speaker basically.

First I hope you remove the speaker wires from the speaker that come from the built in amplifire. You cannot hook the powered sub to the amp without doing that first. Then all you need to do is run speaker wire from the sub out of the box to the amp. In no way can you hook up any other part of the powered sub, but the sub itself, to the amp. If you know the wattage of the sub and the ohms then wire it to the amp correctly. Your phoenix amp will put out 125 watts x 2 at 4 ohms and 250 watts x 2 at 2 ohms and 500 watts x 1 at 4 ohms bridged. Remember, only the sub itself in the sub enclosure can be connected to the amp. Hope this helped you. Let me know if you need more help.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/mark_b53a7494531bf96d

Hello missywarden,

According to the specifications, the amp is capable of "tri-mode" operation, that is, running normal speakers on the individual channels while also powering a subwoofer in bridged mode.

Your sub needs to be a minimum of 4ohms and should be relatively efficient. I'd look for a sub that has an RMS power range of from about 75 watts up to a maximum of 250 watts.

The sub connects to the leftmost speaker terminal (positive - right channel) and the rightmost speaker terminal (negative - left channel).

It's not going to be a really loud subwoofer. The power is 360 watts RMS which will be shared by the normal speakers and subwoofer.

Hope this helps.

may haveto turn sub on through the stereo itself if rca cables are good.

If you have to hook up other speakers through the sub, then it also amplifies the signals for the other speakers too. You can purchase an new amp for your sub here.

You will only need to connect the door speakers to the MRA-F350. In short, the connections will be as follows:

Deck---->MRA-F350 amp---->Door speakers
...................................\---->Sub amp---->Sub(s)

Just make sure you use the optical digital output of the deck to connect to the optical digital input of the MRA-F350 amp, not the RCA preamp connections.
