The winding on the voice coil are coated with a varnish to keep the from shorting to each other. If the sub is drivin to hard or the voice coil is not vented properly. the voice coil windings will get so hot the varnish will melt or someting get sticky. When you quit playing the sub, say overnight the varnish cools and acts like a glue and will cause the voice coil to stick to the basket of the speaker. Repair just would not be worth the money or the time. Plus when a speaker reaches thid stage. It could eaisily fall to short and burn out your amplifier.

I have Sony xm-2165gtx amp 165 watt rms x 2 at 4 ohm 200 watt x 2 at 2 ohm 400 watt x 1 bridge output at 4 ohm stereo or bridge mono output 4 ohm stable in bridge mode this mean can't go lower then 4 ohm...


You can't bridge that amp onto a load lower than 4 ohms. So you can't bridge that amp onto two 4 ohm subs. To get the most power out of your subs is easy. Run one channel to one sub and the other channel to the other sub. 165 watts RMS is plenty for most subs.

What kind of amp can adequately power P112 S8 subs


you shouldnt run it at 8 ohm it shows what ohms it can handle . to run it at 1 ohm you would need 2 subs to do this. and no i wouldnt run an 8 ohm sub on the amp.

What size amp needed with a sony explod player?


this bandpass enclosure is rated peak power at 1200 watts . what this means is that each subwoofer in the is peaked at 600watts to make 1200 watts . what your looking for is to power up the subs with rms continuous wattage . you need an amp that will put out 400 to 500 rms a channel to run this sub enclosure at 800 to 1000 watts rms to keep the speaker from blowing

71671968.jpg this amp will give you 1 channel @ 4 ohm x1 350 watts 1 channel @ 2 ohm x1 900 wats 1 channel @ 1 ohm x1 1800 watts you would have extra power for better subs with more power later but you get 900 watts which when connected right would mean 450 watts per sub be perfect for you . i sell this for $320.99 in my store can shipp any where in usa to contact me caraudioquestion@gmail.com

I have 3 hifonics zeus Size: 12 inch Impedance: Single 4 Ohms Peak Power Handling: 800 watts RMS Power Handling: 400 watts Sensitivity: 89.9 dB Aluminum Cast Basket American Spider For Reliable Performance...


Hello king3132,

Three 4 ohm subs can be wired parallel for a 1.34 ohm final load or series for a 12 ohm load. If you have the channels of the amp bridged, I hope that the subs are connected in series because the Sony XM-2200GTX is NOT rated for or stable at 1.34 ohms. It's only stable down to 4 ohms.

You definitely will not get the maximum potential of the subs from that amp. They can handle 400 watts RMS each (total 1,200 watts) and the amp is only capable of 500 watts RMS into 4 ohms (less at higher impedance), so each sub could only be getting a maximum of 166.6 watts RMS.

Hope this helps.

Not a problem just a question


  • 100 watts RMS x 2 at 4 ohms
  • 200 watts RMS x 2 at 2 ohms
  • 400 watts RMS x 1 at 4 ohms in bridged mode
  • stereo or bridged mono output
  • 4-ohm stable in bridged mode
  • Tri-Way capable
  • requires 8-gauge power and ground leads — wiring and hardware not included with amplifier
  • 50-250 Hz high-pass/low-pass (12 dB/octave) crossovers
  • wired remote included for fingertip control of Punch Bass (0-18 dB boost at 45 Hz)
  • MOSFET power supply and output devices
  • MEHSA mounting technology increases the heat transfer from the MOSFET output devices to the heat sink, for higher power output, lower operating temperatures, and greater reliability
  • TOPAZ — noise-killing differential inputs that eliminate 80% of ground loop noise
  • Trans•ana circuitry keeps preamp voltages low and signal paths simple for outstanding audio quality
  • NOMAD — advanced protection circuitry for "intelligent" shutdown protection
  • speaker- and preamp-level inputs
  • 11-1/8"W x 2-3/8"H x 9-7/8"D


  • Wire your sub in bridged mode (4 ohm mono)

    Rockford Punch HE2 wiring question.


    if your sub will handle it, bridging it will give you more power. The best thing to do is to find out how much power the amp puts out ( RMS ) and if it is in your power handling range bridge it. It sounds better and gives you a harder punch because of more power.

    Bridging 800a4


    That all depends upon whether or not the sub you are running has dual voice coils or just a single voice coil. The 800a4 is a four channel amp; thus the only way you can bridge it will be 3 channel or 2 channel. If you are running a dual voice coil sub then you can wire the amp two channel and get 400 watts x 2 @ 4 ohms. Make sure that you sub can handle this kind of power though.

    Here are the specs:
    4 x 100 @ 4 ohms (13.8V - <0.05% THD)
    4 x 200 @ 2 ohms (13.8V - <0.10% THD)
    2 x 400 @ 4 ohms bridged (13.8V - <0.10% THD)
    Fuse: External 60A
    Manufactured in 1999 - 2001

    Speakers


    400 watts delivered to 300 watt speakers the only way to do this would be to wire two subwoofers in series so that the power needed to drive them will be 600 watts to max, however this will increase your impedance on the speaker (8 ohms) load so what you can do to compensate is get an 8 ohm 600 watt resistor and put it in parallel with the speakers you will then have 4 ohms of impedance at a total capacity of 600 watts of power In other words the amplifier won't blow these out now.

    Speakers


    Hi Trim God,

     

    I do not reccommend that you push the Pioneer speakers over 100 watts.  The jenson will already drown the car with bass through your pioneers so much you will want to turn off the bass boost when playing some low bass hip hop songs. It changes from one venue of song to another, so I just keep the jenson bass boost off and use my head unit to adjsut the sound to fit my listening prefences. I am telling you man, you will be blown away .  Hook up the pioneers straight to the Channels,. do not bridge.  I put Subs in my truck though.  I used the Pass output to send the audio to me Jenson 2 Channel 600W amp. I drive one 10 inch enclosed JBL Class A/B Sub. I bridged the output of the 600 W amp to the 10 inch sub  in my Z28.  The pioneers never get drowned out.  I did smoke my 2 channel Amp one time. and also took out a MTD 10inch sub. I am talk shooting flames and smoked the whole car up. I think if you bride the XA4150 to the pioneers, you will have the flaming smoke problem in no time.
