I was on 95 south, driving at about 75 and my car died. I had just replaced my subs, and when its working it while hit pretty hard, then pop the shuts down for seemingly no reason. it trips at the battery terminal circuit breaker for the system, I disconnected the system by the breaker and drove it another 250 miles without a problem, flip the breaker, and itll hit a few seconds and sudden death to the car. please help as I have to continue to fl tomorrow and itd be nice to have some music. Thank you DJ

It's probably not a cap but if you thnk it is, remove it from the system. ------------- Support the12volt.com

You didn't actually tell us whether you had a cap or not...
If you have a cap, remove it, as suggested, and try it without... I doubt also that it is a cap issue, but more likely you have wired your woofers incorrectly.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Pull it... try it without.

I would recommend NOT putting a capacitor on because it's useless other than looks. All it does is draw current from your battery and then when your amp turns on it just shoots all that current out and charges again and so on. Capacitors were designed for bridged AC to DC circuits not constant current flow circuits so like I said. VERY pointless. Don't mean to dump on your parade.

Who dumped in here? Can you explain your bridge from ac to dc comment? I am not being smart here, I'm actually being quite stupid and curious of the theory. In the realm of capacitors, it would be nice to have a sticky in this forum on the facts(of capacitors) and not the myths. Pros and cons, that type of thing. I have had a few different brand caps installed and in one vehicle i had a parasitic drain on the battery. The kind where you park the car over night, wake up the next day and the car won't start. Thought it was the cap. Blamed that p.o.s. and uninstalled it. Still had the drain. Swapped out the big beefy alternator for the stock one luckily I still had. Problem solved. Wow, I don't think I helped the original poster here. Sorry about that.
