Need help please!!!!
Ok I have a Pontiac G3, here are the specs of my system so far.
Stock head unit
4 JBL GT5-652D MIDS
2 Dual XINBP-212 12inch Subs 600w
Dual XIA3145 2ch Amp 580w
My problem is that when ever I turn up the volume past 30 on the stereo the whole system cuts out
and I have to turn everything back on. Is this a problem due to my wiring or is it a head unit issue
?
Also I was wondering if I were to line the sub box with foam if it would help give a cleaner bass sound? It is a non ported box.
In the new year I am planning on getting a pioneer in dash touch screen head unit and new JBL subs and JBL Amp but until then I am haunted with this problem of the system cutting out.
Please help me with this I have no idea what is going wrong with the system. Thanks to who all get back to me!

im no expert but sounds like the amps are going into protection!!
did you check and double check your wires for any loose or frayed wires that could be shorting out? i had one single strand cross over from + to - at high levels on a sub before.
also what is the max volume level on that head unit? you should only be turning the volume to 70% of max volume, any more and you are in the unclean signal zone (not good for amps or speakers)!
to verify its not the HU itself get a ipod, cd player or anything portable you can plug headphones into and connect it to your amps using an stereo jack to rca cable.
if you have a high level interface it could be that! try the portable device first to see if the amps are ok, but check those wires beforehand.
a good, properly spec sealed box would give clean bass to begin with! what do you mean by "cleaner bass sound"?
there is alot of controversy about adding foam or other types of material in a box for better deeper sounding bass. something about fooling the sub into thinking its in a bigger box.. like i said controversial!
btw what type of foam are we talking here? if its spray foam, the short answer would be no. if you mean rigid foam insulation. i still say no. most people would use pink insulation or a sound absorbing mat material. its up to you and your ears!
im sure more experienced peeps will chime in soon!
oh forgot to ask what type/size of power wire you are using! could also be the amps are starved for power and shutting down.

The head unit max vol is 75. I checked an rechecked the wires and they are all good and I have it so that non of them could even come in contact with each other they are out pretty well. I am also concerned about the way I installed the amplifier. Because I don't want to reck anything trying to get at the back of my head unit (don't know how to get at it lol it's a 2008 not sure how to take it apart) but since I could not get to the back of the unit i spliced the rca's into the current of the rear deck speakers. I read somewhere that u could install the amp like that too but could that be the problem that the output to the amp is not directly coming from the head unit?
And by foam I meant the pink insulation I mean the bass sounds clean I was just wondering if there is anything to do to the box to give it that little bit more clean sound. I know that i have a lot of rattles coming from the trunk and that will have to be fixed with some dynomatt or something like it.
Right now it is a 8 gauge wiring kit from canadian tire I for get what brand it is. I will try the ipod thing too!

You mean u used left and right rear speaker leads and hooked them to Hi level inputs on amp right? You said you spliced to rca, saying that sounds to me that you put rca jacks on speaker leads and plugged into lo level inputs on amp? If thats what ya did then thats a no no. If you hooked your speaker leads to the speaker hi level inputs you should be fine.
If you disconnect your wires(rear speakers to amp) does your head unit still shut down?

yup
you found your own problem!
high level output to low level input
its not his head unit that is shutting down its the amps... too much power on the low level input causing the amp to protect.
sounds to me like you are one who is better off not doing your own installs.. i suggest you have it looked at by a professional. also disconnect your amps before any more damage is done. if its not already too late!

when I say that the whole system shuts down I mean from the head unit all the way to the amp. You guys are right it was the high level leads from the speakers into the low level on the amp. I have disconnected the amp and subs until I get into a professional to install them properly. No damage has been caused because when I took the amp and subs out the stereo does not shut down on me anymore.
Is there a way of getting around this my self or would it just be best going to a professional to get it done?
Thanks.

That amp has hi level inputs on it, put the speaker leads to those inputs and ur good to go.
Or get a line out converter, its a small device that safely changes youre speaker leads to lo level rca inputs to ur amp. Google "line out converter" and you will find all the info u need. You can pick up a cheap one that will do the job at walmart.

first read the manuals that came with the amp/s!!
second as sunfired has stated your amp/s are capable of high level inputs.. meaning the amp has a line level converter built in. while they are not always the best it will do since you plan on getting a new hu which will hopefully have rca outs.
there should have been a small connector probably with wires coming out of it that came with the amp. thats your high level connector used to connect your speakers off the hu to the amp. yes you can connect the wires that go into the rear speakers to this.
i do have a ?
do you only have 1 Dual XIA3145 2ch Amp?
if so how are you running 2x subs and 4 mids off of this???
its a 2 channel amp that does
100rms x 2 @4ohm (145rms x 2 @2)
or
290rms x 1 @4ohm bridged
you dont have tweets in your setup?
whats the ohm rating of those subs?
give us more info on your configuration please!
from what i can see the bad wiring was only the first problem you were having.. bad speaker configuration for your amp was the second!

Thanks I will check out the "line out converter" for now, but once i get the new hu I will have it all professionally installed.
nghtrdr.... I was only running the amp to the 2 subs. i was not running it through my mids.
I don't have tweets (yet) and the subs are 4 ohm.
