whenever im playing music with loud bass from the subs, the lights on my accord dims or "blinks" almost like its shorting out the battery.. does anyone have same problem or maybe know anything about whats going on ? tnx for replies..

 

Can you give us a little more info? What amp/sub combo? Do you have a capacitor? What gauge power wire?What type of battery do you have? Have you double checked all power connections?

 

Big 3
Capacitor
Battery
Alternator
Power Isolation system


That's the order of upgrades that you need .... now if I knew how much power your 12's are pulling, I could tell you how far down the list you need to go.

 

hmm awesome awesome tnx guys .. and yeah uh i dont have a capacitor .. dont know what that is neither do i know what gauge power wire is? and i only have stock battery .. and the fuse that i have going from the battery to the amp and subs is 120A i think .. the subs are eclipse so is the amp but i dont know how much its pushing .. decent i would say .. probably nothing lower than 500w each .. sorry thats all i know for now . tnx a lot for the tips tho . much appreciated . anything more ?

 

1. A capacitor basically stores current up during "normal" listening levels and releases it on the big hits.
2. Check your power wire to see what gauge it is. (8, 4, 2, 1/0)
3. I would suggest a high performancebattery like an Optima.
4. Google the model number on the amp. It should give you specs.
5. Check all power connections! (make sure they are free of corrosion and tight)
6. Check all power connections again!!

 

It doesn't sound like you are pushing enough power to need a high perf. battery, alternator or isolation system. Go to an auto store and have them check out your battery. It may just be on it's way out. For capacitors, a good rule of thumb is 1 Farad per 800 W-RMS .... a lot of people say 1000 Watts, but I derate them because they loose capacity over time just like a battery.

 

are capacitors easy to install? would it be available anywhere local ? or only online?tnx
