soooo... i recently got someone to put subs/amp in my car... and for some reason all the lights in the car (including head and tail lights) were blinking to the bass. then my car just died and wouldnt start til we shook the battery terminals. what's going on!? when i got the car it already had an older headunit in it that blinked when it was turned up loud. i have no idea what the problem is but i don't think its the battery because its fairly new...? i have the fuse out now so it's not taking any additional juice. can anyone help!?

thanks (:

lol its draining your battery. Mine kinda does that too... the eclipse alternator sucks lol

i had the same problem, but on a Ford Escort, it is probably your alternator, that was my first thought but i dont think your sound system is powerfull enough to have your car die (how many watts is your amp?) ... that seems odd,
check your alternator, or maybe even buy a stronger one.
I bought a rebuilt alternator for my Escort, and the car ran fine and so did the system.

oh... btw, you can get a capacitor for the amp, ~ 2 farads

Bull****... i have a power cap and it still sucks

Did you charge your cap before using it?

Make sure the wire going from your battery to your amp is at least 4 guage power wire with at least a 60amp in line fuse. You also might want to get a new battery, especially if the one you have is older than 5 years. Just to point out once more that the power wire has to go DIRECTLY from the battery to the amp, if your friend spliced the power wire into your electrical system somewhere (like the lights) then you will have problems and possible a fire.

Yea it was on there for quite a while... and yeah my lights still went a little dim lol

ya i would get a fraed cap and a deep cycle optima battery if that dosn't work can get a higher amped alternator, ya what gage (size) wire do u have running from your battery back?


im runing 2000watts and my lites would dim but not go out. all i had to do was get a fread cap and that fixed it but i already had a optima batt

I always use 0 guage for amps.

yea i agree its the alternator cuz my dodge dakota did that, or u could have so much power that ur battery cant handle it lol thats all i know

hay i got a 90 eclipse gs that i bought from a friend and my dash lights dont work and the fuses arnt blown and the light arnt blown can neone tell me what it is?????????

Ok first off its not excactly the alternator because sure the alt sucks its not a high watt alt but if you put the right farad cap in it should put your power hits back to when it was stock for example i have 05 Lancer ES and if i have my radio turned up all the way i take power hits and thats stock no mods to system gettin a better alternator or putting a 1 or 2 farad in stock system could solve that but when i put my system in i plan on puttin at least a 2 farad cap in and i might put a higher watt alt in a better battery yes helps but a cap and alt will fix it but a new alt is more money then a battery so if a cap and battery fix it then great it also depends on what type of amp you are runnin i will be runnin a 1000watt 2ohm stable amp so my advice would be put a 2 farad cap in and see if it helps then replace battery and if you are still takin hits go with a new alt
