Always something small that gets overlooked
Yes, I think the rust is definitely a good starting point for troubleshooting.
You see, the path of current in a vehicle is FROM the NEG. TO the POS. ....
alot of people think it's the other way around.... and therefore, your system will only be as good as your grounds.... this goes for engine performance too!
Upgrade your battery grounds, and redo the grounds on your gear....
Clean, Bare metal is best with a star washer under the ring terminal.
As far as the amp turning off, it could be a lot of things simply because there's more than one peice of equipment in your electrical "line of supply"
Try un hooking your subwoofer leads from the amp... if it still does it, unplug the RCA's, if it still does it then go buy a new amp orrrrrrrrr...... beat up the dickhead that sold you a bad one.
If the problem stops after you unplug RCA leads then chances are you got a pinched wire...... that just reminds me.... check your entire length of wires:
Check:
Power wire
Rem. wire
RCA's
There could be a pinch in the wire from something or any of them could be grounding out.
if you inspect all your wires and nothing's pinched, bent, kinked or grounding out, then unscrew your subs, being careful not to "port" the rubber surround on the woofer^_^ Did that once, me + beer + installing = expensive.
Check the subs.
If you have access to a Digital Multimeter that has a continuity setting on it do that test on the woofer by spring-clipping the red lead to your pos terminal of the woofer and the black lead to the neg terminal .....
Now place the meter where you can read the display while you move the cone in and out thru its travel. When doing this you want to make sure that you're not exerting extra force in any one direction. You can avoid this by positioning your hand as if you were going to palm a basketball, now place said hand over the cone of the woofer and press down with your fingertips. You can aslo go from opposing sides of the woofer and move the cone in and out.
What this test will tell you is if there's any breaks in the voice coil. They'll usually show up more prominently on the ends or middle of either an outward or inward travel.
As well, as this test you can test the resistance of the woofer(Ohm).
Should read somewheres between 3.7 and 4.2 Ohms for a 4Ohm Single Voice Coil wooferif you get a reall y high or low reading then there's a good to great chance that you're in the market for some new gear
Dunno about you but that's kinda like Christmas for me
Damn!.....I blowed it up!.....................Cool!.... I get to get new stuff!
Lemme know if you got the issue nailed.
For me it's always something "simple-stupid"... It's either simple or it's stupid.
And then you laugh about it while you turn up the tunes and enjoy your new hearing damage devices
