lights dimming

Where did you install the capacitor ? You should be as close to the amplifier as you can get without it interferring with the amp. You may have needed another 1/2 farad .

It could be that a Cap is not enough for your vehicle. You didn't tell us what kind of car you have, so I can't give you good facts, but often lights dimming is a symptom of the charging system being insuffecient for what is being drawn. A Cap can only supply current for an extremely short time - The attack of a bass note, for example. Then, it has to recharge itself off of the battery. Adding a cap may only delay the dimming to just after the hit instead of in sync with it. It may be a good idea to check out you alternator - How much is it rated to put out (amperes)? With a little more info, like what kind of car you have and such, I could help more. It seems from first glance that your alternator can't keep up, and that woudl be the first thing I would check.

thanks a lot  it was a ground problem with my capacitor i had to move the ground cable .....and i might change my alternator too .

can you help me with another problem i bought an after market fog lights and i taped it to the low beam but while i am driving on the high way  my headlight keep shuting off and flickers can you tell me what`s the best way to hook it up and if not using a relay is creating that problem. thanks a lot.

No all the fuses are fine but it seems like it`s happining after driving on the hiway for a while. is there any way to hook it up so it will come on with both hi and low beam and shuts off when i turn the headlight off or the ignition....thanks  a lot  .

Hi nazmy08817, your situation is not uncommon and now is as good a time as any to offer a friendly word of caution/advice......before you add any more accessories, I'd upgrade your alternator to accommodate the total demand you plan to put on the electrical system. The main purpose of the battery is to start the vehicle and the purpose of the alternator is to supply all current needed by any device and to keep your battery charged. While beefing up the ground from the battery to the chassis is a very good idea, it's just as important to beef up the power lead from the alternator to the battery and the ground from the case of the alternator to the chassis and battery. When the vehicle is running, absolute ground is at the case of the alternator. If your total current draw exceeds the hot output of your alternator, you'll always have a problem with supplying enough current to any given device when current draw exceeds the alternators output, as well as keeping your battery charged. If the alternator can keep up with the total demand, adding stiffening capacitors will help when the alternator can't supply the immediate demand for current, but if the alternator can't keep up with the total demand, over time the dimming problem will reoccur as your battery will be drained. Continuous demands for current that exceed your alternator's output can also cause damage to the diode bridge in the alternator, dead batteries, and possibly leave you stranded.  oO(....whew!)
