Trouble shooting ideas for why my subs don't work

[Rambug]

Sounds good. Another thing you should really do is fuse or add a circuit breaker to the power line coming from the battery. The last thing you want to happen is to get a short and burn down your truck.

There is a fuse in there! 100amp i believe it was!

 

[Rambug]

Cool...after all that, ensure up have a single line running from your stereo remote output to the remote line on the amp, and good RCAs and you should be good

 

[4x4Hemi]

Why would i have more then one haha? is it possible to have more then one?? oh and its 150a fuse haha i don't think it matters though really

 

[Rambug]

Just trying to help you make sure everything is hooked up properly.

 

[4x4Hemi]

Oh i didn't mean it rudely i just mean is there a way i screwed it up some how! sorry about that confusion

And just to clear it up i meant i don't know if it matters that i meant 150a vs 100a!

but now i am sure its all good!

the first thing i am going to say may rub some people on here the wrong way but first thing you need to do is eliminate ANY connections you have covered with electric tape....that is a sure fire way to end up with a bad connection. that is the big difference between a professional job and some joe blow on the corner who does the job you already got if you know what i mean.

 

[4x4Hemi]

I dont "Pigtail" anything if i can help it, i don't like to connect it by electrical tape, i don't think its a permanent job. I agree with that though, i just have electrical tape on bare metal so it doesn't touch, its not connected that way though.

This is what I meant by one single line for the remote line...some people will try to make a wire longer by splicing it in multiple pieces. Use butt connectors or preferable a god solder connection with heat shrink over it if possible

 

[4x4Hemi]

Ohhhh thats what you meant, i was a little confused there. I've used butt connectors on all my splices with the head unit and all that. bought a 50 pack of em!

 

[olbaid_83]

so is it working now?

 

[4x4Hemi]

Nope...put new ground and power terminals on it. Sanded the **** out of the ground and NOTHING. I don't even know what to do anymore. I'll try re wiring the subs, put different speaker wire in there I guess...

Also does it matter what gauge wire I have running from the subs to the amp?? I just used speaker wire

 

[Rambug]

Do this....find a speaker....any speaker....hook it up simple...find out if the amp is working.

 

[4x4Hemi]

Okay I'll try that

 

[olbaid_83]

i have a strong feeling the channels are fried. what head unit are you using?

 

[GhostRam94]

yeah im really thinking at this point its a bad amp

 

[4x4Hemi]

I'm feeling that as well sadly. It's a clarion vx409 headunit. The guy I bought my head unit is saying it was working a day ago... He answers my text messages so If he knew it was broken when he sold it to me, why would he continue to answer my texts?

Could it possibly be the inputs from my headunit for the rcas are no good ?

 

[Graygoose]

I agree with bad amp,

simple way to look...

Grab a known working speaker, even a coax 6.5" you have in garage, test on the speaker outs of the amp, no sound, then amp is bad or not getting signal. It has power, so it powers UP, but doesnt mena it has output.

If it's RCA's, get a good set, run from back of HU and just lay across the seat and run to amp to see if it suddenly works. Isolate the problem, one thing at a time. Its' RCA, HU or amp.
I 'think' amp sounds culprit...too bad you didnt have access to another amp, lay it beside, swap over RCA, power, ground, remote and speakers and see.....

 

[4x4Hemi]

I did the RCA test and all that, and it wasn't the RCA chord. I meant could it be the rcas out of te head unit?? Just wondering if it's a possibility? My buddy has an amp that I can test on and see. Give that a go
