Ok my car is actually at my friends shop and he took them out for me and said that on two the spiders were burnt by the leads so he covered the leads and still the same issue occurs.

I have an issue with my amp protecting at a high output. The subs are wired to ohms in an 8 cube enclosure tuned at 38. When I take it into high volumes it gets louder without distortion. When it starts getting to its peak my amp throws a short circuit protect. Is it possible that one of the coils have an issue? Or possibly amp? The setup is four fi ssds on a stetsom 7kd. Also coils read exact same on each eight coils.

Yes I did

I have not sir. That will also be tried

That sounds like a for sure culprit I'll take a look at it tommor and see what happens

The leads are externals.

Yes, I never read a dead shortbb

Stetsom 7kd one ohm I have even measured it while it was playing nothing out of the ordinary

Cant be it still reads a dead 2 ohm as it should

The amp only has a low pass. It's set to 50hz it's the lowest it can go.

Series/parallel each coil is ohm ohm with distribution blocks.

The vehicle is an '89 mustang (hatch). Im wanting to keep the enclosure at right around 10 cubes to keep my imp rise at about one ohm but want a different port placement. it is possible that this may just be a wall but im looking for the best gains, what should i do? the build is with four FI SSd 12's thanks guise.

Ok, so i can lose a cube or two and keep my efficiency up? if that is the case than ill be in great shape but I'm struggling to figure what sub/port placement will benefit me best.

wired it to 2 ohms and still have the same problem. is this protection triggered by output only?

I finally installed the stetsom 7KD (1 ohm 12 volt) and it ran very well but just yesterday it began going into protect.It throws a protect with one blink and the manual tells me that its a short circuit or below impedance.I'm running the amp at a half ohm nominal. It starts doing this when i roll into heavy bass. I triple checked all of my connections and everything is solid, voltage is in mid 13's when it cuts off.

oh, no. i just love car audio. i did this for sheer fun... and to scare deer away so i don't hit them at night ^-^ i would love to get metered though. You will be fine at 2 then. Thanks, ill try 2 ohms and if i still have problems, squaretrade has my back.

Well thank you. that really boost my spirit. I guess i lucked out. good luck with that build though.

you're very correct about them being sensitive. but i think that I'm starting to understand this. The damping factor is killed when playing music at loud volumes and because of that the impedance can fall below the nominal load? Impedance can fall to the nominal load, which in your case is .5 and too low for them amp. ok, ill wire it to two ohms and see what happens! now I'm butt hurt because I'm "that guy" that couldn't run his 7 K at a half ohm

You need to be concerned about your starting impedance. you wouldn't mind explaining to me how the amp sees that when its not putting out would you? Thanks.

that's only nominal impedance. reactive should be close to 1.7 or so, im thinking?

So i purchased a stetsom 7KD and I am curious what the external fuse rating is. i looked up the manual online but it only has info for the two ohm version. The one i purchased is the one ohm 12 volt version. Also when i install this amp I will add another battery or two to what i have.I have noticed that a lot of setups have unfused connections on their terminals. As of now i have two batteries with two fuses 12 inches from each terminal. so if i install a third would i need another two fuses or would that only be necessary if they were a certain distance apart? And of course when i do the install i will do another positive run and dual input terminals. Thanks

Maybe i could give circuit breakers a try? or would that not be in my best interest?

For now it has single inputs, but I plan on putting in some dual input terminals on them. the closest battery to the amp will probably run 24-36 inches.
