New Dual XIA3145 2/1 LED glows red, guide claims speaker problem

Channel mobil power amplifier hooked to a 4 ohm 10" subwoofer. input is from car radio output.

Status LED glows red "protect" or fault, its supposed to be green, guide claims speaker problem (crossed wires, defective speaker, or improper ohm rating (less than 4ohm load) . Wires not crossed. 4 ohm subwoofer is supposed to be ok for this amp, tested it on 6 ohm speaker, still red. Tested speaker in bridged and unbridged single channel, still red.
Speaker tests ok on another amp.
Amp is no

    thank you howdiuhhhh.



    You were exactly correct.

    Ground wire was attached to body but paint on body work was interfering with good connection.

Look at these and only these... power or ground...either your power wire has grounded out somewhere (ud be surprised) or youdont have a good enough ground....i would check the ground first....hopefully this helps

How do i wire alpine swr1243d subwoofer


There are a couple different ways you can wire up this speaker as it is a DVC speaker. Duel Voice coil, it has two + post and two - post. A dual 4-ohm voice coil subwoofer with its coils wired in parallel presents a 2-ohm load to your amplifier. Since an amplifier produces more wattage at a lower impedance, the parallel connection ensures you'll get the most output from your amp.
Series wiring lets you configure multiple woofers to one amplifier at an acceptable impedance. Wire both coils in series for an 8-ohm impedance, and then wire two 8-ohm subs together in parallel for 4-ohm total impedance.
You can wire each voice coil to a separate channel of your amplifier, if you prefer not to bridge your amp. Independent wiring is a nice option if you're wiring two DVC subs to a 4-channel amplifier - one voice coil per channel
Depending on what you are hooking it up to i.e. a mono amp or a bridged four channel amp. I can tell you post to wire exactly if I know how you want to hook it up and what ur hooking it up to.

How do i connect a sub wooferto my reciever


I own 2 of these Pioneer VSX-D903S units.

The only way to hook a powered subwoofer up to a VSX-D903S is if your subwoofer is equipped with amplified/speaker level terminals on the back, in addition to the line-level input. If you only have a line-level input, do not attempt to hook it up to this receiver.

If you're lucky, and have speaker-level inputs on your powered subwoofer, you would use the amplified terminals (connect to B-channel on the receiver). DO NOT connect anything to the line-level connection.

Alternatively, you could build two unpowered subwoofers, then set the receiver's Impedance switch to LOW, then connect one enclosure to each of the "B-channel" outputs. Connect your regular left and right speakers to their corresponding "A-channel" outputs. [Impedance range: 4 Ohm minimum, 16 Ohm Maximum]

How do you hook up the speaker wire to the ab sub out and what is the best way to hook them up at what ohm


Not sure what you mean by AB but being that this is a monoblock or 1 channel amplifier you can only hook it up 1 way. Verify the polarity from your speaker box. + to + and - to -. As far as your impedance is concerned this amp is stable to 1.5 ohms but for this case we will assume you have two 4 ohm subwoofers. When you parallel these together you will have a total effective load of 2 ohms on the amplifier. This is a stable operating impedance for the amp.

Other impedance options are:

two 8 ohm speakers = 4 ohm load
three 8 ohm speakers = 2.66 ohms

If you have dual voice coil subwoofers then parallel the coils on each sub + to + and - to -. Depending on the impedance of each sub you may then have to wire the individual subwoofers in series. Here is an example.


2 dual voice coils with 4 ohm taps

Each subwoofer with the coils in parallel would be a 2 ohm load if you were to then parallel the two subwoofers together you would have 1 ohm total load on your amp. This is BAD for your amp. Your option is to run the subwoofers in series.

To run the speakers in series is simple. The + from one speaker and the - from the other will be connected to the amp. The other + and - from the speakers will be connected together.

Here is a wiring diagram from kicker.

(To the guy [dunnbiker] that says there's no rear channels: You're wrong.) The VSX-D903S has 2 stereo (A/B) channels, dual center channel (place center speakers to the left and right, or above and below the screen), and two rear satellite channels. It is a 3-Ch Logic/Dolby Pro-Logic Surround equipped receiver, not a DolbyDigital/DTS multichannel x.1 surround unit.

    How to wire 2 dvc subs to a orion 2150sx ? dont know the wire colors or how to hook um to my amp.


    what impedence are the voicecoils?
    Dual 4 - Dual 2 - Dual 1 ??

    Orion SX / GS / HCCA amp Wiring guide:

    Orange = Right Positive
    Black/ Orange = Right Negative
    Yellow = Left Positive
    Black/ Yellow = Left Negative
    Blue = 1+1

    Bridging of SX or HCCA Amps:
    1. Use the Orange wire for Positive.
    2 Use the Black/ Yellow wire for Negative
    3. Push "in" the Mono Button
    That amplifier is only 4ohm mono stable - so assuming the subs are dual 4 ohm voicecoils...

    First wire both in Parallel Independently So each subwoofer is now a 2 ohm load. (combine + and + - and- on both subwoofers)

    Now Take a positive on one voicecoil of sub #1 and attach to amplifier+(orange)

    Take a - on that same subwoofer and attach it to a + on the OTHER subwoofer.

    Finally, take a - from the second woofer to the amplifier -(black/yellow)

    Now you have a 4 ohm load on your bridged channels.

    I'm assuming the subwoofers were bridged and couldn't handle the power. Make sure you have atleast 300 watts peak power wattage.
