Troubleshooting amp setup

I have a 600w 4 channel bridgable amplifier which 2 front speakers are connected at 150w each plus a 300w subwoofer. The sub isnt producing much bass at all. The rear speakers are hooked up the stereo head & now not working at all.

What have I done wrong???

Also can i connect all 4 speakers by bridging them to the amp as well as run the sub?

Can any1 help me....driving me

    Thanx, it is a VG 640 Tenvox 600watt amp

    It worked in my previous car & produced good bass & ex sound from speakers. Using all the same equiptment just in a different car.

    Hi thanx for that

    No thats a problem, the person that installed it in the first place must of thrown it out as i dont have it. I too have been to Tevox site! When I removed the amp from the old car I left all the wires on the amp, so thought it would be easy enough to install again

    I cant do it now as its almost 1.30 am but tomorrow i can write all the connections & crossovers etc down & post on here if it would help.

    tanya_i: any info would be helpful. having access to an install manual would point out any additional options that the diagram on the amp may not have the ability to demonstrate. is the tenvox VG 640 not a commonly found item in Australia? is there a car audio facility near-by? i know outside of the main cities, there are large distances between towns. we'll keep at it until we get this solved.

    i'm not familar with tenvox, but most amps install about the same way. some have additional options vs others. bottom line i need to see a copy of the install manual. i visited tenvox's site but they don't have archived manuals on line. i've written them requesting some info. do you have a copy? if so, can you scan & send it to me? once i see the wiring diagrams i can help you.

    I need the model # of the amp before I can help. respond with that info. Generally the purpose of bridging the amp is to drive a single speaker such as a sub-woofer.

You probably need your remote wire re-hooked and make sure the ground wire is good and the remote wire is connected to the right wire(the red wire).

I have a sound stream xta 600.2 what would be the best 12" subs to with it

match your total rms output at the resistance you will be running the amp at to the subs.
if your amp puts out 300w RMS@ 4ohms, then it will produce 600w RMS@ 2ohms. half the resistance, double the power.
So now that you know your available power, you should get speakers that will be used to the fullest at that given resistance.
If you have two 4 ohm subs that have a power handling of 300 watts, Then you can wire them in parallel ( + to + and - to -) to get a 2 ohm load (which will be 300w per sub with the above amp) or in series (+ to - to + to -) to get an 8 ohm load. (300w amp @ 4ohms = 150w amp @8ohms = 75 per sub).

Keep in mind: choose the speakers to fit the amp, not the amp to fit the speakers. If the amp has more power than the speakers can handle, you will blow them. and ALWAYS USE RMS WATTAGES.

Total Power Bridged in 2 or 4 Ohms ?

Nice amp the specs say the following:
4 Channel 100W x 4 (4 Ohm)
4 Channel 150W x 4 (2 Ohm)
2ch Bridge 300W x 2 (4 Ohm)

But.... it tends to go into protection quite fast so i wouldn't go too low with speaker impedance.

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

    Kicker 8 inch 4 ohm subwoofer 200 watts rms?

    Max 200 W. You could bridge 2 channels of a 4 channel amp (or get a 2 ch amp and bridge it) and connect the sub. Bridging = connect + of sub to + of one channel, and connect - of sub to - of *other* channel. Check amp manual for instructions.

    Don't get a mono - most are 300W or more - might burn the coil during loud passages.

    How many speakers can I use?

    This should work if channel 3 & 4 are bridged at 4 ohm.
    channel 1 should be stable at 2ohm
    channel 2 should be stable at 2 ohm
    You can hook up the right side speakers together ( + with + and - with - ) . same thing with the left side. this will give you 2 ohm each channel. this will cause your amp to run hot (this might be tuff on the amp). It will give you right (2 speakers) and left ( 2 speakers ), no front and rear adjustement if you need to balance your sound. I think you should be better buying another amp for your sub and take your 4 channels for your 4 car speakers. this amp as a rca output that can feed the other amp ( sub amp ). it is possible to do it.

    Good luck

    MRV - 1507 Question ...

    The MRV-1507 is a two channel amplifier, below I've pasted important info from the manual:

    Battery Lead (Sold Separately)
    Be sure to add a 80 amp fuse as close as possible
    to the battery’s positive (+) terminal. This fuse will
    protect your vehicle’s electrical system in case of a
    short circuit. If you need to extend this lead, the wire
    gauge should be AWG8 or larger.
    MRV-1507 ... 80A amp fuse

    Power Output: RMS Continuous Power (at 12.0V, 20 Hz to 20
    Per channel into 4 ohms ......................... 150W, 0.08% THD
    Per channel into 2 ohms .......................... 300W, 0.3% THD
    Bridged into 4 ohms ................................ 600W, 0.3% THD

    You can find a manual for this amp here:

    Planet audio vx3002

    Sorry wayne2953 but this amplifier isn't stable @ 1ohm loads. This amplifier would be better suited running a pair of 12's, 4 12" subs could run if configured correctly but the subs would be underpowered and probably not sound very good.

    Features of Planet Audio VX3002:

    • Max Power (2 Ohms) : 300W x 2
    • RMS Power (4 Ohms) : 150W x 2
    • Bridged Power (4 Ohms) : 600W x 1
    • Signal-to-Noise Ratio : 102dB
    • Frequency Response : 20Hz-20kHz
    • Dimensions : 10-5/8"W x 2-7/16"H x 16"L
