Righteo. Have a Sony 12' sub and amp. Sub keeps cutting out when turning, and finally gave up totally this weekend. Chekced all wires, seem fine, nothing loose. Amp has been known to overheat since it cannot handle the power the sub needs, but give it a little cool down time and it is fine. Have also checked motherboard of amp for scorching, nothing there. I'm kind of stumped. Was thinking of getting another amp and hooking it up to the sub to see if that is the problem! Any other suggestions! TIA

lol, yup. If I go to turn it cut out sometimes, then when I turned again it would come back. That's what made me check the wiring.

Seems weird, haven't come across is before. Do you have electric power steering!

Turn the gain down for a start to stop the over heating and give the amp some breathing space.get a fan if you need to. I would check all the wiring again, including RCAs as they could be faulty. Remove each wire from the sub and amp individually and inspect, cut and re-strip if necessary making sure all connections are firm when re-installing.

Was considering just getting another amp to match the RMS of the sub so it won't be overloaded all the time. It was overheating even with the gain lower. It does have space, just no fan, which never helps!
I have stripped, reconnected and tightened all wires. Don't know how to check RCA's since they are plug-ins. It has me rather stumped, but I'm 95% sure it's the wiring.

Does it matter which way you are turning! Could the steering rack be messing with the main +ve wire!

the amp wont 'overload' driving a speaker rated higher than the amp. It just wont run it very load. unless its a dual voice coil sub and its wire 2ohm bridged on the amp. sounds like there is a short somewhere.

Yes it has been bridged, don't know if it's dual voice coil however.

Dry solder joint!

The sub used to stop, then sometimes cut back in when turning again. Will check wires again tonight.

Be specific. What part of car/audio setup!

I'm guessing he's talking about the +'ve and -'ve on the sub. Yes it is dry, don't know why it would be wet.!

lol, you're kidding! Prob remote (usually the thin blue wire) at back of head unit. Check back of headunit and get back to us

Considering we are talking about an amp what else would I talk about. An amp lol
quote : It might also be sensitive to vibration or movement.
Hence the whole turning thing.
Have you checked the remote turn on and everything else with a test lamp or multi meter.

lol, my bad. Don't have access to multimeter or test lamp unfortunately.
I shall check the remote turn on soon. Have had trouble with it from the headunit before.

Sorry, been really busy. Will try and get round to it tomorrow and keep you all updated

Dry solder joint means not connecting. Is everything including amp screwed down tight! Check, check and check again. (inculding the wiring between head and amp) Assume nothing!

Well, if we're talking about the amp. It could be any one part of the amp, internal or external connection points, (there are many) it could of also been the sub, headunit, and any other part of the car (in relation to the audio setup), since that is what the amp is attached to. Judging by the reaction of the OP to your question, I assume you may need to be a little more specific.

Quote from first post : Amp has been known to overheat
Dry solder joint also get worse with heat, then mentioned the movement. When he mentions SPECIFICALLY the amp is over heating and the AMP is the issue what else would it be. The op does not know about dry solder joint so trying to get them work it out is beyond them no offence op.
jono2912,

So that means everything else is presumed not to have dry joints! I'd be out of work if I always assumed that.
And I'm pretty sure nothing is beyond explaining to the OP. Surely people still know how to learn.

Going by what I have read, they have checked all the wiring etc. I didn't say it WAS just one possible thing to look at it upon investigation. Has dry joints do not like movement and heat.

Turns out the REM cable was not plugged in properly to the constant power source behind the headunit and was only barely touching, hence why it was fading in and out around corners. Cheers everyone!
