my lights go dim when the car is under pressure for example the windows or when the heating is on , whats the story , regulator or alternator or battery
do have a lot of audio equipment in the car? If you do, adding a cap will help a lot. If not, you'll either need a new alternator or have your current one rewrapped to provide more amps.

it is a capcitor like a small battery that stores electricity for heavy bass notes or when u need extra power u can get them at crutchfield .com here is the linkcruthchfield
also i would go with a bigger alternator this would help a ton not to difficult to install either also lighting also has a special battery made for audio stuff it can bewired inseries with your old battery or can just replace it if u had two batteries a capcitor and a 150 amp alternator your car would never dim again
a 1 or 1.5 farad cap would almost or totally eliminate the power draw issues. Basically you need .1 farad per 100W. the smallest caps are around .5, or 500W. You need a minium of a 1 farad, but theres nothing wrong iwht overkill either. Im only pushing around 900W with a 1.5.
They install between the amp and the battery and the amp draws power from the cap and battery simultaniously. When the battery can't keep up, the cap kicks in and sends more juice, so you end up with a higher battery charge and a less stressed alternator.
I used some of the factory CD changer brackets and modified them and made a custom mounting bracket for mine.

i have a 1 farad cap in my car. its ment to store energy so when the system (the subs) kick hard and take lots of energy the capacitor has stored energy to use instead of putting such a strong stress load on the charging system.
thanks alot guys much appreciate the help. Just to let u know Spieluhr , i got the new sony head unit with memory stick etc, there is so many gadgets in it , sony had no place for an internal amp , so for the radio to work i had to buy the 1000 watt
