Check your remote wire... usually your remote wire isnt connected properly; or your fuse from the battery to the amp is blown

Either the speaker is shorted out (blown), or the output transistors in the amplifier are bad. Try hooking up another speaker to the amp. If it plays, the amp is good. If not, then the amp is bad.

What amp would be better to use with what speakers/sub? I have a KAC-7202 kenwood 920W maximum power (150wX2 RMS, 4ohms) (230wX2 RMS 2ohms) and then the other amp I have is a Alpine MRP-M500 mono power...


I'm using that Alpine right now for 2-12" subs and I have compared it to 6 or 7 other amps this month and most were 4 channel 150Watt/Channel Bridged to 300Watts x 2 and found the Alpine to be superior in both sound quality and loudness. The Alpine has also not turned off even with full volume for hours at a time, Very solid amp I was very surprised due to it's size!

Is the sony xplod cdx-gt71w able to support a subwoofer without another amp


Sure is.

The sony is bridgable as follows:

  • 100W x 4 @ 4 Ohm
  • 100W x 2 + 250W x 1 @ at 4 Ohm

  • This will allow 2 channels to run 100 watts each @ 4ohms with an additional single channel with 250 watts @ 4 ohms.


    The single sub channel is created by bridging channels 3 & 4

    I Have a Sony Xplod 800 watt amp and 2 12 inch Sony Xplod subs


    You should definately bridge them. Firstly, lay the 2 speakers face down next to each other. Note the connections +- +-. The first + will go to the amplifier. The next terminal(-) will be connected to the next speaker(+). Take the last(-) and connect to amplifier. Please note that your amplifier has a bridge section which is normally the first + and the last- on the two channels. Connect your woofers on the bridge.

    Getting my son a sony xplod xm-1652 2 channel what subs would sound good and the things says 1000x2 and 500x2 what is the truth


    165 watts x 2 @ 4ohms and 200-230 watts@ 2 ohms or 400-460 watts bridged into a 4 ohm mono load is what the amp will actually do. A single 12 inch sub or a pair of 10 inch subs or 12s would be great

    Random Protection mode.


    Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Clipping means you have exceeded capacity. .A thumbs up would be greatly appreciated if this answer is helpful to you. random-protection-mode-lv2kkrmxrai4iihdvw4m3np2-1-0.jpg

    Got a 12"kicker L74ohm sub and sony xm-D9001GTR mono amp


    Hello juan_penaloz,

    The Kicker L7 has an RMS power range of from 50-750 watts and a maximum power handling capability of 1,500 watts so your Sony amp will power it OK. A more powerful monoblock like the Alpine MRP-M1000 or the Kicker 08ZX750.1 would provide even more power and could operate safely at 2ohms.

    You have the voice coils wired properly for the Sony amp. It's OK to have the sub impedance higher, but you definitely do not want it lower than the 4ohms the amp is rated at in bridged mode.

    Hope this helps.

    Can I run 8 speakers and 1 sub through 1 1200watt 2:1 Sony Xplod?


    asuming the 8s are 4ohms each; wire two in series and that gives you 8ohms then two more in series then you put those together in parallel and it gives you a 4ohm load. repeat with other four for the other side. you should then be able to bridge the sub


    series; posative of one speaker to negative of other speaker and that doubles your ohms

    parallel; posative to posative negative to negative and that cuts the ohms in half
