Woofer problems

[Shay91Racer]

Ok so I have 2 12" JBL and RF type x5 amp right now I only have 1 sub connected because with both it cuts in and out. It does it with just that one as well but not as much. I can play my music at a certain volume and it'll do it less but when I turn it up, it'll go in and out. I'm thinking I may need a capacitor but I'm curious to make sure before I spend money. What do you guys think?

[sonikaccord]

Are your connections good?

[Shay91Racer]

yeah.. i called myself running them down and checking everyone.

[sonikaccord]

How long has it been happening?

[Shay91Racer]

since i got the setup. It was minty. got it from my dad when he took it out of his m3. If i'm on the gas, its like it get more juice and it'll start back hitting. So that's why I was hinting at a capacitor.

[sonikaccord]

hmmmm. do you have a multimeter?

[Shay91Racer]

yes and no. what do you have in mind?

[sonikaccord]

wait what does the amp do when the car is off?

[Shay91Racer]

?? it works fine.

It sounds to me like the amp is simply not powerful enough. But I guess the problem might be deeper than that because I assume it worked fine in the M3?????

It sounds like your amp is clipping, which happens when you try to drive the amp harder than it's capable of being driven. How do you have the voice coils wired? Perhaps your amp can't handle the ohm load you're trying to run it at??

[Shay91Racer]

IDK whats going on. Could it be possible that moisture maybe causing this?

I would bet your problem is, you're trying to run your amp at a 1 ohm load, which could end up frying your amp. You can wire dual 4 ohm voice coil woofers in either 8 or 1 ohm. Try wiring it at an 8 ohm load and see what happens. Granted, it'll drop your power rating on your amp, but it should run with no issues.

My next suggestion^^^

only problem is i just looked at them... they're bridged. positive and negative.



unless you meant this... but it's for SVC
