Question: what starts to smoke, the speaker or the amp? I'm assuming it's the amp. It cant be a fuse because that's what fuses are for to cut the power on an overload or surge. I would have a look at you circuit board for the amp My guess is what you;ll find is a burnt spot on the board and that will tell you what component is bad and needs replacing. Good Luck

Testimonial: "It's the Speaker that starts to smoke. The amp doesn't Smoke and that channel gives off powerand plays music through the speaker, but for some reason it burns every speaker I hook up to it. The speaker will puff up and stay puffed until it burns out."

if setup 4 channel amp with low pass filter for the sub channel and other 2 channels for speakers with no filter, some amp you can use amp as 3 way if one or two subs, bridging output will give you more power for the sub. be aware that bridging 2x4ohm subs will give you 2 ohms and potentially damage the amp.

How do I hook up one sub to my rockford fosgate p3001 amp

Hey i have looked over many rockford manuals,(i own a 300.1 my buddy owns a 325.1) and for there mono(.1) amps there hooked together on the inside so channel A+ and B + are cencted on the inside the amp. So you ither hook one 2ohm sub to channel A or you can hook 1 4ohm subs to channel A and 1 4ohm sub to channel B. There 2ohm stable so any lower will eventualy burn the amp out.

1 channel is out in my Rockford Fosgate P6002. One day everything is working and 2 weeks later the one channel went out. I have the amp hooked up with 2 12'' DVC T2 or T4 Eclipse Subwoofers, sorry not...

Hello jason_dil,
Having 1 channel go out is a common problem with audio systems. Unfortunately, since it can be caused by faults in the wiring, head unit, amp, or the speakers themselves, it is tedious to troubleshoot. Being tedious doesn't mean that it is difficult. You can do it with a little planning and organization.
Here's a link to which has pages and pages of step-by-step troubleshooting. I recommend that you read up just a little and print out any of the guides you need.

What you want to do is eliminate what ISN'T causing the problem and isolate what is.

1) First, do a physical check of all the wiring. Make sure all connections are secure and tight and that there are no obvious cuts, tears, or breaks in the insulation. Check all fuses. Either replace them with known good fuses or remove and check with a meter. Check RCA's plugs on both ends. Remove and reseat each plug. Make sure the pin is not broken off inside.
2) Move on to the defective sub and it's wiring: See if it works on the other channel.
3) Check the head unit output: Reverse the channels of the RCA's and see if the problem switches to the other sub.
4) If everything checks out in 1-3 above, you've isolated the problem to the amp itself. It probably has a faulty component and will need to be repaired or replaced.
Hope this helps. If it does, please rate as "FixYa". Thanks!

Sony xplod 500w 4/3 channel

If the speaker is a 4 ohm DVC (two 4 ohm coils), you can't wire it to get a single 4 ohm load. Try connecting one coil to each of the two rear channels. It may not be as loud but the amp should operate without going into protection.

If the two 4 ohm coils are in parallel, the amp is driving a 2 ohm mono load. That's probably why it's shutting down.

P5002 rockford fosgate

If you hook up speaker and hear a pop you more then likely have 1 ch blown causing dc on output. You can use multimeter and measure voltage for both ch,s between positive and negative terminals..One channel will more then likely measure 0v and the other one which is defective wll measure a dc voltage. These amps have what are called mehsa bars which output transistors are mounted to. Need to contact Rockford fosgate 800-669-9899 to arrange for flat rate repair.
