I have a JVC 4 channel, 540W amplifier.
I’m not an electrician but I try.
So I connected all audio and speaker cables correctly.
I run just one kenwood 10″ subwoofer.
I gave power for the amplifier through cigaratte lighter port.
Now when I turn on the bass a bit loud the low power indicator on the amplifier blinks and sound disappears.
Is it because I connected the power through cigarrete lighter port?
or
My battery is no good?
or
Do I need a capacitor?
or
Something else?
Many thx!
You need to run at least 8 gauge power cable from your battery! You need to ground it to some metal bolt in the back of the car.

My upcoming car setup for my bmw is a JVC headunit, Rockford fosgate T20001 bd amplifier and maybe 1 Rockford T1 or T2 15″ or 2 Rockford T1 or T2 12″ subs, by the way what is better 1 15″ or 2 12″? where do i get more bang for the buck? but my main question is, do i need to upgrade anything in my car? like battery etc? i am not a carshow contestant, just for normal daily use and i dont really turn the system to the max, just average. 5***** for best informative answer. THANK YOU!
I’m going through the same process of upgrading to a massive sound system. Go with the 2 T2s in a ported box (unless you are crunched for space). You’ll make better use of your amp and you’ll get significantly more sound. These are my recommendations (most of which I am doing): ** Uprgrade the wiring of the “Big 3″ in your car (order about 12-15 feet of 1/0 gauge wire for it online for much cheaper than what car audio shops will charge you); **Find out the fuse rating of your amp, then look at the amperage rating of your current alternator. Most stock alternators are 65-90a. Your car needs about 50a to run all the electrical. Lets say your amp has a 150a total fuse. That means you need a high output alternator that will power 200a total (if you will never really push the system to full power, you can get away with a 150a alternator). So you’ll either need to get your current alternator rewound or buy a ho alternator. If you try to power that much with a stock alternator, your alternator will fry and you’ll have to get a new one anyway; ** Get a kinetik or optima battery. The hc1400 is a really good deal right now online. You need a battery like that to give it consistent and prolonged power.
