I've had this amp for 3 years now, and never had an issue. In fact, I bought another for my other car since I had no problems!

Well, the original one has a problem that developed about 2 months ago. After about 6 or so minutes of hard bass; the amp cuts out. It will come back after about 1 minute every time.

I thought it may be overheating, but I took the back off and there was nearly no dust/crud, and the fan is working fine.

Any ideas?

 

Start by measuring the resistance of the sub.

 

...?

 

Do you have a DMM (mutimeter)? Do you know how to use it?

 

If so toss it across each of your subs coils and report your findings. If not run to radio shack and buy one. They're about $20 and are extremely useful.

 

Yes I do have one. These are DVC subs... what is the method of doing this?

 

Set the DMM to read resistance. Put one meter lead on each of the terminals for one coil at a time. If there 4 ohm VCs you should see something like 3.5 ohms per coil. Post up what you get for each coil.
