Question about JBL GTO75.4 Car Audio Amplifier

1 Answer

Left speaker channel not working

Hi there, I just installed a 1200 Watt Juice JA590 amp. It's a 2 channel amp and can also be bridged. Therefore, I have hooked up a pair of 6 x 9's and a sub in bridged mode. I have checked the wiring several times and I cannot see any fault. However, when everything is powered up, I get sound from the right 6 x 9 speaker and subwoofer but (No sound coming through the left 6 x 9 speaker). I think I've eliminated each possible problem and have concluded that the most likely problem is with the amp itself. If it is, what do I do and who do I go to? Please tell me what you think? Your help is very much appreciated. Many Thanks.

You may have to send it in or back to the company... being that its one side it could be a blown amp or perhaps a bad speaker on that side ..

hooking up two 6x9s and a sub in bridge mode you could have a wiring problem when i bridge an amp i go from positive of one side and negitive on the other to the same positive and negitive on the sub or box



+--------------------\
` bridge =========== > SUB

I have the Sony explode 1200 2/1 channel amp and 2 comp series lighting audio 10s 8ohm 900 watt max best way to hook up for loudest bass


You will have to wire subs together for a 4 ohm load. Then bridge amp (1 channel). Look on amp speaker outs to see what leads to use to bridge. Run positive and negative to one speaker then use a jumper wire from that positive and negative to the next speakers positive and negative

Amp comes on running 2 12" 450 watt pioneer subs, volume only seems to be about half output, with speakers bridged


This could be the reason. If you look at the specs for this amp you will see that the continuous power out is rated for 380W bridged. The speakers rated at 450W should be able to handle close to 315W continuous. Now if you split these numbers being you have bridged these speakers, you drive each one up to about 190W continuous. The speakers are being driven approximately by 60% of the rated capability. I personally like to keep it right where you got it, not exceeding 80% of the speakers rated capacity.

Here are the specs for the AMP:
  • Specifications
  • Peak Music Power 760 Watts
  • Number of Channels 2
  • Load Impedance Capability 2~8 Ohm (Stereo), 4~8 Ohm (Bridged)
  • Continuous Power (4 ohm) 125W x 2
  • Continuous Power (2 ohm) 190W x 2
  • Continuous Power Bridged (4 ohm) 380W x 1
  • Frequency Response 10Hz ~ 50kHz
  • Total Harmonic Distortion 0.008%
  • Signal-to-Noise Ratio 100dB
  • Dimensions 12" x 2-3/8" x 12-3/4"
  • Features
  • Bridgeable
  • Channel # Capability 1/2/3
  • PWM Regulated MOSFET Power Supply
  • Screw-Type Speaker Terminals
  • Balanced Isolator Input Circuit
  • RCA Inputs 2 Channel
  • Input Level Control Hi-Volt (200mV ~ 6.5v)
  • Built-in Crossover Selectable LPF (80Hz, -12dB/Oct.)

    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.

    How i wire my sub to my jbl gto301-1iiamp with 2 Hifonics HFi12D4


    If the amp is 1200 watts at 2 ohm stable you will want to set up the speakers as parrallel and bridge the amp. That means conncect the speakers with + to + and - to -. Look at the amp connections. Usually thereare connects that look like this:
    + -
    + - + -

    If yours look like this use the diagram on top. You will use the + for the left ouput on the amp to the right - on the amp. This will allow you to use all the power from the amp. Be sure to lower the gain as to not pop the speakers or amp.

    No sound


    What size subs are you running? Also what wattage are the subs that you want to use? Also what I would do is to start out with a smaller speaser just something like a 6x9. Just enough to hear sound. From there I would make sure that all cables and wires are hooked up accordingly. DO NOT BRIDGE CONNECTIONS until you have verified that you get sound out of each channel. I have a 1200 watt amp in my car and do not have a cap in it. It seems to be fine. The only thing that a capacitor is good for is if you decide to use you system with out it running.

    2 ohm speakers wont work on a lanzar max pro 4000 watt


    The 2 ohm stable rating on the amp is PER channel meaning that you could effectively hook up a 2 ohm speaker or a 2 ohm load to each channel without the amp getting f"d up-butin bridged mode it will only be 4 ohm stable. to achieve a 4 ohm load with your sub the type x wire the coils in series that will get you at 4 ohms to run in bridged mono .But you will get the exact same amount of power if you wire each coil to one channel of the amp as bridged mono sees the sum of your 2 ohm channels combined-Hope that 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

    How many speakers can I use?


    Hi,
    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
