The amp turns on with a green light but the bass output is very low when i tap on the top of the amp it bumps for a split seconed and then stops usually when i tap on the side with the speaker outputs

Check the connections to the amplifier. Make sure that the insulation

for all wires has been stripped back far enough to allow a

good contact area inside the terminal block.

Check the input connectors to ensure that they all are making good

contact with the input jacks on the amplifier.

What screws are stripped on the amp? The input for power or speaker inputs?

X621 excelon amp has red light on, stoped workin all of the sudden now a minimum sound exports with a bit of static. do i reset it? what do i do and how?

If disconnecting all power wires, and replacing all fuses (including inline ones) doesnt reset it. then its toast. Hate to break it to you :( Contact the manufacturer if you feel it is under warranty.

All wires are connected but i have no power to my amp.

Hello laramoe,

For the lowest resistance connection, your ground wire needs to be in good solid contact with bare metal of the vehicle frame or body within about 18-24" from the amp. The ground is probably the most important connection you'll make to the amp. A bad one will not only rob your amp of the current it needs for best performance, it could result in damage to the amp or the vehicle itself. The ground should be the FIRST connection you make, and you should spend some time making sure that it is a good one. At the absolute minimum, you should test the "resistance" between the negative battery terminal and your intended ground point. Anything above about 5 ohms and you should look for a better ground. 2-4 ohms is OK, but you'll lose some input current and that means less output. I like my meter to read 1 ohm or less, before I'm really happy with the ground connection.

You may need to pull back plastic panels and/or carpeting to get to the metal. Then, find an existing bolt or screw that goes into or through the metal (a seat bolt is good, and most trunk, hood, and many dash screws go into metal). If you are unable to find an existing screw or bolt, you can drill a hole and attach the ground with a new "self-tapping" sheet metal screw. If you do decide to drill, use a drill stop and be VERY careful around any lines or hoses. Use sandpaper or a small Dremel grinder to remove any paint, undercoating, or soundproofing materials from around the hole. Crimp the ground wire to a "ring" terminal and put a toothed lockwasher under the terminal. Make sure that the head of your screw is sized to completely surround the ring terminal and tighten it until the lockwasher bites slightly into the metal. DO NOT overtighten, or it will strip and come loose. If you wish, you can cover it with dielectric grease (like mechanics use on battery terminals) or you can seal around it with silicone. You can also spray-paint it with a corrosion resistant paint. Rust Oleum flat black works well.

Hope this helps.

How do i intall my amp?

first you need to run a power cable for the battery to where ever you are going to place the amp DO NOT hook the cable to the battery until the very last just wire it to the amp for you will want to ground your amp hook the ground wire to the amp and the other end to a solid piece of metal in the car this is very important if you don't get good metal on metal contact you'll blow a fuse. If you can hide it well strip back a bit of carpeting and use sand paper to remove all paint from the metal and drill a hole for a screw. once that is finished you will need to run a remote wire from the amp to the car stereo usually these are the blue wire on the harness in the dash. once that is hooked up run the rca cables (reds and whites) plug in to amp and then in to back of cd player. once this is all hooked up and fully secure hook the power cable to the battery make good contact and if everything is grounded right you should get the lights on in the amp. Next step hook up the speakers run speaker wire from the amp to your speakers make sure negative goes to negative and positive to positive or you'll get clipping and it will sound like ****. that's pretty much the jist of it. if you have any questions let me know.

Power screw stripped for JBL Car AMP GTO 75.4 II

Actually I buy them in lots of 1000 and I pay 38 cents each for them. They are 24k gold plated. They are the real deal. If you do the math you can see I do not make much of a profit at all on them.

Amp problem

I don't know of a surefire test, but i had an ov2-400 gothic amp that i bought used and it had the same issue, or at least very similar. first thing to do is hook it directly to a known good source, if that fails, use the high inputs.

the fix for mine was to disconnect the amp completely, open the case, and spray everything down heavily with CRC QD Electronic Cleaner, it costs about 5 bux at any autozone and is extremely handy. this fixed the issue, i then sprayed the connectors down with rid-ox and used an rca adapter as a cleaner (ie inserted it into each socket while wet and rotated it a few times), also installed a new set of rca cables just to be on the safe side.

in my case the amp was stored in a trunk and had something either spilled or condense in it, a good cleaning of the board took care of the problems and it has been working now for the past 4 months.

hope this helps,

Rockford 1001bd blowing fuses...

It sounds like you've got a short to ground in either your power line or internally in your amp. Either that or the fuse on your amp (usually right on the side) might be blown. Check your power line and make sure that your amp isn't screwed directly to any metal parts of your car, as some amps will short like this. If there's nothing wrong with the power line, send it in for warranty or bring it to your local audio store to have them check it. If you feel comfortable with trying to fix it yourself, then take it apart but be advised that internal screws usually have a glued spot so they can tell if you've disassembled it.

No sound

I would try it without the slot for the additional amp. However, there is a chance that it is fried. When its powering up I would check the voltages with a multimeter to make sure everything there is in order.
