I have a power stiffening capacitor on my main bass amp line, one with the digital display. Can this be draining my car battery overnight?

    Thanks for ur reply smarthome2. The amp (hifonics brutus BXi1206D) turns on via remote from the deck, so i know it shuts off when i turn off the deck. The capacitor's display however seems to stay on for a very long time (maybe an hour or so) can this be enough to bring the battery down? Also, the only other thing that i have on overnight is my viper car alarm. I doubt that this can drain the battery... what's ur take on that?

    Thanks again smarthome2. I found out that my alternator was the problem. It was not giving out the right voltage..but enough to make the charge light on the dash go out. Since then i've replaced the alternator. However i have a problem with engine noise coming through the speakers when the engine is on. It seems to be from the power lines since its still on when i disconnect the rca audio in jacks. Is there anyway around this without having to install a power noise supressor?.. i didn't have this problem before replacing the alternator.

Generally, no. How is the amp triggered? Is the amp always lit up (power)? will your deck turn on without the ignition key? If all this is ok, you can go to any auto parts store and they will check your charging system for free and usually give you a printout of the results. A stiffening cap is similar to a battery except it is designed to discharge and recharge very quickly. If it is bad, your battery would die in minutes not hours. Hope this helps

    How long have you had this equipment in the vehicle and how old is the battery? The LED display pulls less power than a wristwatch, and your alarm pulls about as much as a clock radio. Have your electrical checked, it's a freebee and what you will probably find that your batt is just beat up. A great replacement battery for anything is an Interstate Cranking. They are designed to take lots of abuse. They are # 1 in marine use since they have massive cranking power, lots of reserve and do not chew up water like a marine battery and best of all, they are the same price as any other typical car battery! 1/3 of the price of a gell cell and two times the lifespan of a typical battery. If you've got any more questions, fire away, I'll do all I can to help.

    More than likely it's your main lead from the battery down to the starter. Pull the connection and check for white chalky deposits on the ends of the wires and at the connection points. Second and probably just as important is the placement of the ground for your amp. Make sure it's to the floor of the vehicle and not a seat bolt or side panel, as the welding points generally don't conduct as well. If you do move your ground, make sure you scrape the paint off the metal and look under the vehicle before drilling any hole! fuel lines and vehicle wiring do not react kindly to drill bits! Check the antenna connection and the chassis ground for your headunit. Noise filters rarely work. Engine noise can be the most aggrivating problem to solve. You didn't have the noise prior to switching out the alternator, so for starters, check the wiring to and from it, clean off the dirt, WD-40 & a small steel brush. clean all your contact points. It can be as small as a ground wire on a turn signal that's loose or broken. Take your time and thoroughly check the vehicle's wiring. Hope this helps, if you have any more questions, ask away, I'll help if I can.

How am I going to connect it to my car,Im wondering why it doesnt have a remote terminal like what the other capacitor brand had.


it's like a battery. you run it in parallel (run power from battery + to capacitor + then from capacitor + to ampplifier +) battery, capacitor, and amp each has its own ground (black or -). you don't need a remote wire. it only stores electricity until the amplifier needs extra juice (so your headlights won't dim).

25 farad cap slowly losing its charg if the car sits for to long


Cap is hooked up wrong, should shut off after a certain amount of time and reactivate with the ignition hot wire. If it's draining your battery continuously then you should look at the wiring.

You hook it up in parallel with your amp. You'll see a and - on the clear plastic cover.
Hook a wire from your amp or positive to the capacitor
Hook another wire from your amp - or negative to the - on the capacitor.

That's it, you're done.

If the plastic cover is missing, or painted over, with the neon tubes at the top, and the connector/display end facing you, the right side is the left side is -.

Amp cutting out when bass hits


With an amp like that you can not pull enough power from you cars battery alone. That is why when it hits hard it drains the amps from your battery and you amplifier cuts out. The light on the amplifier most likely dims when the bass hits. You need to get a capacitor. They are easy to hook up on the main power wire. You can get one from http://phatcaraudio.com/capacitors.html or get a used one off ebay.com. Good luck

Headlights flash with bass


The sound system is exceeding the capacity of the Alternator, it takes allot of power to run the subwoofers, they make higher output alternators for just this situation, u will need one with at least 130 Amps output.

Voltage drop


You're drawing a ton of power from the car's electrical system. Get a stiffening capacitor and put it in on the amp's main power cable. If you're draining the car that badly, make sure to get at least a 1 farad cap, bigger if you can, and until you do, turn the gain down and don't run so much bass - you'll kill your battery in the meantime.

Ashdown Perfect 10 Bass Combo keep blowng 2 man fuses


What main fuses? Fuses in the car electrical system? If so, your amp is too powerful to run through the cars electrical system, you should get a heavy guage wore ran straight from the battery, with its own dedicated fuse placed in-line, ad close to the battery as possible. Wait, is this a bass guitar combo??? Open it up, if there's wax coming from the power supply, thats prolly the culprit. Check for any obviously blown resistors or any short circuits. But most likely, its not gonna be user-servicable.

How can i get my power to my EQ?


What kind of eq is it? First thing I would do is hook up the +12 and GND to the same place the amp is hooked up. I think the eq is having a hard time getting ample current, therefore shutting off all the way when the bass hits. Caps are good, but second battery and battery isolator are far superior.

Optimum sound performance needed


1) legacy products are highly overrated and i have never seen one put out the power it claims
2) if you are running the amp bridged, you need to match the impedance of the speakers to the amps highest output impedance, otherwise your system will not sound all that great...

what size fuse or fuses does your amp use? what size wire did you install with (power and ground)? did you connect direct to battery or did you connect to a fuse block or similar? did you use a stiffening capacitor? does it sound like it is clipping when you turn it up or is it just distorted? what kind of box are you using for the speakers (ported, vented, sealed, bandpass)?

if you give me the model number of your speakers and your amplifier i can probably help you more, but with the information you have provided, this is all i can offer..

hope it helps,
trin
