Question about JBL GTO75.4 Car Audio Amplifier

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

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

Will the amp blow my speakers?


If you bridge the amp and get 1000 watts RMS and that is split going to two speakers then you will get 500 watts RMS at each speaker. If you have your amplifier on maximum gain it may blow your speakers, not because they are overpowered but because you might run into "clipping" issues running the amp at maximum capacity. Just to be safe I would dial the amp's gain down to 3/4 of the way to full gain. That should give you ample power and keep your amp from clipping and running hot.

i have found the specs to your amp. 1. Amplifier connections: Lets make things simple. As we look at the amplifier speaker connections, we will number the outputs 1 2 3 4 from left to right for the top connections and again 5 6 7 8 from left to right for the bottom connections. 1 should be connected to a positive (RED) (+) on sub woofer A on voice coil (a) 4 should be connected to a negative (BLACK) (-) on sub woofer A on voice coil (b) Now using a small piece of cable, connect negative of voice coil (a) to positive of voice coil (b) Follow the same procedure for the other sub woofer using 5 and 8 as 1 and 4 This configuration should make the amp run at 4 OHM BRIDGED x 2. i hope this helps. dreamsystems

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.

What kind amp should be use for ts-w307d2 subwoofer speaker?


Nice sub, i have 2 308d4s in my car. Okay this sub is a dual coil 2 ohm. so to get best bang for your buck you'll want a 2 channel amp and bridge it. Your sub is 400 watts RMS, So you'll want an amp that has the same rating. I'd recommend the pioneer GM-5400t. Then wire your voice coils in parallel, and bridge your amp, you'll get 380 watts RMS, which is perfect for this sub. If you have questions on wiring or anything you can just ask. thanks, i hope this helps

Pyramid makes the PB series of amps. I have one that's driving a Sub.
The PB 700 puts out rms 60watts x 2 @ 2ohms, which gives you some "headroom" for your speakers. You don't want to over drive speakers with , for example, a 1000 watts for 100 watt speakers, because that's a good way to blow your speakers.
There are many brands and models of amps that will fit your speakers. Just make sure the amp will drive 2ohm speakers, since your jbl's are rated at 2ohm impedance.
You may want to consider adding a Sub woofer to your setup. A single Sub would fill in the low end very nicely. If you got a 4 channel amp, then two channels will drive your jbl's, and you can bridge the other two channels to drive the Sub. That would be a kick'n sound!
Just make sure the amp is bridgeable
For example, the Pyramid PB 1200 is a 4 channel, bridgeable amp. This particular amp will drive the 2ohm jbl's, but you would want a 4 or 8 ohm Sub connected to the bridged channels.

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.

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
