Problems with FI Q 10

Recommended Posts

Hey guys i have a FI Q 10 that is run in .5 cu ft sealed its run by a Rockford Fosgate T2500bdcp.

Problem is that when you get any kind of power going to it the driver seems to unload starts popping like its has reached the mechanical limit and this is what i would consider to be at a very low volume not sure what to look for to figure this out is there anyone that has had same problem. Please help really want to hear what this thing can do any advice would be apperciated.

How did you set the gain? What are your head unit settings? What coil configuration, and what is it wired to? Can you provide a photo of how it is wired? Is the enclosure 100% seaIed? I know that I have asked a lot of questions but it will help narrow things down.

Fully loaded with hi qts dual 2 ohm coil wired down to one ohm. The head unit is set with sub out at -3 63 hz on the crossover gain is only about a 1/4 of the way up and yes it is 100% sealed

That is a shitload of power for a Q. Can you post a pic of the sub and how it is wired? What does your electrical consist of? HOW did you set the gain? What head unit do you have?

2500+ watts on a 1200 watt sub might be the problem man..way too much power.

Gain down and zero out HU setting instead of -3 or whatever you have. Actually put your gain to the absolute minimum......

If it is clanging..that means the coil is running into metal. This is either caused by a leak in the box, or too much power..or a combo of both.

That amp will do ~1400 at 4 ohms. Try wiring it to 4 ohms.
