Rockford Fosgate Audio Players & Recorders - Recent Questions, Troubleshooting & Support

We need to know what the amp is and its model, what the speakers are, what the enclosure is.

Depends on your sound pref. I do 35 hz lowpass, full on subsonic.

Take two wires, equal length. Reach from positive of 1 coil and hook too positive of 2nd coil, now do the same with negative, neg to neg.. Then pos of sub to amp. And neg of sub too amp.

tough one i have no clue

Chances are that more than a fuse went. I would follow (internally) the path of the wires from the speaker you mentioned - inside the amp. This should bring you out to the main amp. I think you will find that whatever powers that channel is faulty.

try opening it and rewirwing it

Hi tazmattiejoe,

• The problem could be with the fuse , check if the fuse is proper and not blown up , if it's burnt then all you need to do is replace the fuse.
• If it's not burnt up then you need to check the input device for the amp and if you can see power being reflected on the amp and it's properly switched on.
• If the amp appears to be powered on but not working then you need to check if it's giving you an out put by changing the speakers , usually the input is the problem , when there is no input in the AMP or there is a mistake in connecting the input to the AMP there would be no output which could make us think that we have the problem in the AMP itself.

Therefore please check the inputs and out puts of the AMP and your CD/DVD player devices.

Hope that helps ...:) Let me know in case you require any further assistance , your feedback would be appreciated.

Fuses blow like that when there's an overload. This is often caused by a semiconductor device that is acting like it is a piece of wire. The most common fault in amps is the devices on the heatsink, that power the speakers. The cost will depend on how much the devices are and how many have gone.

Only a human being looking at the possible physical damage could assess it. Obviously, something electrical and vital is making marginal contact. On the other hand, you also have the potential for something electrical and UNdesired to be touching. I'd proceed with caution. Get it to a shop.

Specs are here:http://www.hertzaudiovideo.com/Doc/S...nica_space.pdf

Basically this is a 6.5" mid (7" outer diameter including the ring for the grill) with a front-mount neo motor, composite basket, and a water-resistant paper cone. Mounting depth is 1.5". It's rated at 100w RMS and 200W max.

Are you turning of the amplifier first or the source of audio? Amps should be powered down first and then the source. If both are powered down at the same time make sure the volume is down or otherwise you will always get a thump. The opposite when you power up. The source and then the amp. Hope this helps.

You should still get sound even with small amps but it would be rather weak. Check first the source of the signal. Test with different sources to be sure. Check for loose connections.

first you have to start by taking out the voltage out from the transistor boards,check the power supply voltage if its ok,the connect one borard at a time.if one bolw the fuse thats the sort circuit.begeing by cheking the transistors and go on.
