I bought a jenseng 7" am/fm/cd/mp3 player etc. not to long ago for my car..which is a 92 pontiac sunbird..

Question

what i'm wanting to know is....why the screen flickers on my 7" flat screen jenseng stereo system when I have my S****y little system going...my system contains of a ..Lightning Audio Amplifier...two 10" Subs in a concealed box in my trunk...two 6x9's ...and there are two other rather small speakers in the front which are not connected to the amplifier...Thanks.

Answer 1

you need more power

Most cars come from the factory with a charging system that is adequate for the vehicle's stock equipment — air conditioner, power windows, defogger, etc — and can provide a modest amount of extra capacity (30-40%). Note that bigger vehicles like SUVs and large pickup trucks usually have larger alternators that can handle an additional 30 amperes of draw. However, if you drive a small car, adding 36 additional amperes of current draw to a system that produces only about 60 amperes of current could be a significant extra burden, one that your stock electrical system might not be equipped to handle.

A capacitor stores electrical voltage and releases it as needed. Capacitors are great if your electrical system is near its capacity and the music you are playing suddenly hits a thunderous, long bass note. A capacitor releases the needed power to meet the demand without stressing the system, then it recharges itself. There are also specially designed car batteries that work like capacitors; that is, they have standby power that can be released as needed.

Answer 2

its flickering because your trigger wire off the deck is losing power when your amp powers up. try testing the remote wire off a switched ign. wire at the fuse panel. if this works wire a relay using your trigger on pin 85, put 86 to ground, 30 to the amp remote input, and 87 to a constant 12 volts(off amp power wire, or at fuse box) 87a just tape off you will not use. your lower quality amps internals are not that great so the amp is drawing more current than it should through the remote wire, this check i spoke of should fix the problem. instead of pulling the deck to check this add a pc. of jumper wire from the 12 constant power at the amp and jump it directly to the remote input. now the amp is on all the time for now but this will allow you to easily check if this is the problem. you can also wire in the relay at the amp location too to make installation easier since you will not have to pull the deck this way.

not enough power try adin a bigger battry or anoda 1
