the other day i noticed a popping noise whenever it hit. I turned the system off from the head unit and took the sub out that night and this is what i found. my question is. how did this happen? I installed everything my self but had someone else tune the amp. I've heard several things that made this happen i just don't know what is actually true.

sub is a kicker comp VR dvc 10"
amp is kenwood 1000watt




the tear is on both positive posts

 

well for one that sub can only handle 800 watts max, and since you had a 1000 watt amp powering it, you probably pushed it too hard.
but i dont know your knowledge with speakers and powering them

 

Too much muscle for your sub or it's defective. Last time I popped one, looked just like that. You can use an amp that's bigger than your sub can handle, but it makes things like this easier to have happen. Hope you get it figured out!

 

What's the model of the amp?

 

It is a Kenwood KAC-8103D 1000w Class D mono block i think its 300rms 1000w max and 500rms at 2ohm. I don't know alot about sound systems just learning about them. but i figured since its 500w at 2 ohm and my sub 4ohm is 600rms i could wire it at 2ohm and be safe. I had ran this set up for about 1 1/2 years in my camaro and now my civic. i guess it just had enough. i planed on doing something different but just not this soon. i can give you the tune on the amp if that helps out any. So it can help me in the future on to how to do it the right way.

 

If your sub is a 4 ohm unit, you would need two subs wired together for the amp to see a 2 ohm load. A mismatch in impedance is what your problem ended up being IMO. Either run 2 4ohm subs together, or buy a sub that's rated @ 2ohms and you'll be fine. Anytime you add a speaker to the load it cuts the impedance in half. So, if you start with a single 4ohm sub and then add another, you then have the 2ohms. Add another sub, it drops to 1ohm, and another yet would put it at .5ohm for a load.

 

Ok so the way i wired it in a 2 ohm way helped in no way. i looked at crutchfield.com for a wiring diagram and i did what the image showed for my set up the class d mono block and a single 4ohm sub. I.E. + to 1st vc then to 2nd vc then same for -. Im just a little confused on what all happend. I don't want to seem stupid. I have some knowlede and want to learn.

 

Sorry, I'm the stupid one here. Missed the part above where you said it was a dual voice coil. Duh me! So yeah, you had it wired right by the sounds of it, so 1 1/2 years regular use if very possibly the culprit here. My 10" RF Punch svc lasted 3 years in a sealed box before it did the same thing, and I'm not saying RF is better than Kicker or vice versa, it's just the nature of the beast. Use your equipment and it will fail eventually, no matter what it is or who made it.

 

Yeah my set up was pretty crapy in terms of the box. it was a duel 10" mtx ported box that i had to cut to fit in the back of my camaro then seald it pretty good. so i also think it didnt have enough air space to function properly. but im not for sure about that. Not very good the technical aspects of the systems i just put 2 and 2 together and some how make 4. QUESTION. would i be safe for my next sub doing a 10" Kicker L5. are they a good sub.

 

I hear ya. My Punch was in a KLH stereo speaker box with the holes for the other components sealed off. Looked f'n horrible, but had nice tight thump. Currently running a Polk sub in a sealed box powered by an MTX amp and am not satisfied at all. Looking to upgrade both in the near future. Sorry, no experience with Kicker subs yet. I've given it consideration lately though.

 

if you have everything hooked up and tuned correctly you shouldnt have any problem blowing your sub. the box could be the culprit. you can over power a sub and be ok on moderate volume but sounds like with that amp and that sub you were right on with power. also your alt or battery could be going out and you started dropping voltage which in turn caused your amp to clip which is basically sending a dirty signal to your sub and caused it to distort and distortion is what kills most speakers.

 

Alright, since i don't have a sub right now. i put my type S 3way 6x9s in. would it be better to amp them or just run them off of the rear speaker wires. i have never amplified them before. so i don't know exactly how to do it. i have a precision audio thump amp 300w, would that work. would it treat them like a sub or can it be a speaker. i have no clue one what it should do.

 

Im not gonna count on anything with this amp.. its model TGA-914 and i can't find any information about it on the inter web.
