Question about Jensen XA4150 Car Audio Amplifier

1 Answer

Speakers This is a great site. Crutchfield has the following specs for my XA4150: 2 ohm output: 100 watts x 4 RMS at 0.1% THD; peak 2 ohm output is 200 watts x 4 Bridged output: At 4 ohms. the output is 200 watts x 2 RMS at 0.1% THD; peak bridged output is 400 watts x 2. The manual says bridged output is for subs. I have Pioneer 4-way(4 ohms)6x9's rated max 300 Watts ea. Can I bridge them instead with the full range selected in the built in crossover? If so, what about the peak output in bridged(400 Watts) being over my speakers max (300 Watts)? I want to get the most power out of my amp for these speakers. Thanks for any help you guys can give.

Re: 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.

    Need help wireing sub

    Is the speaker a dual voice coil speaker? If so you can wire it up a couple of diferent ways, go to they have a woolfer wiring wizard that can show you the different ways to wire for 8 ohm.....4 ohm.....2 ohm....and 1 ohm...I would figure out how to get the most power out of the amp in mono mode, take that ohm load from there and see if you can wire your speaker to match it.

    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

    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.
