Question about Lanzar 4 Gauge Digital Installation Kit w/1.2 FARAD Capacitor Car Audio Amplifier

1 Answer

Capacitor First my subs started working off and on for no reason. I have a 4 farat capacitor and it normally would say 14 volts or so. Now when I turn my car on it says 8.4 or so. The subs do no sound and after a couple minutes the display on the cap just turns off. I can hear that the amp is on like a whirring noise. Please let me know whats up.

    Fixed! The ground had melted fiberglass all over it. I cleaned it and bolted it down properly. Thanks a ton!

Sounds like a bad connection to me, check all your cables,

Most likely to be an earth, so check all your earth cables including the battery earth, its always a good idea to upgrade your battery earth anyway, It will be better that way anyway

NO SOUND OUT OF SUB WOOFERS I AM GETTING POWER TO THE AMP


the easiest thing to do is check the voltage at the amp, between the red power wire and the black it should be the same as the voltage across your battery under the hood. now turn your radio on and c heck the remote turn on wire this wire is at the amp and is usually blue it should have 12 volt when the radio is on and 0 volts whe the radio is turned off check between the blue remote wire and the black ground wire unhook subs from amp and check the resistance across the speaker terminals with a digital mutimeter, if your subs are 4 ohms then your reading on the meter should be around 4, if it is close to 1 or 0, then it's probibly your subs. if everything is good check the fuse on the amp

Subs Won't work when wired


Hi,

Based on your post/description, pls try:
1. running the amp's power without the capacitor;
2. manually trigger the amp with the head unit off. Run it an determine if the backfiring still will occur (even with the head unit off);
3. temporarily interchange the left/right wiring;
4. temporarily interchange the + and - speaker wires;
5. run the amp normally trioggered by the headunit but remove the RCA connectors towards the amp.

If your concern has not been corrected or diagnosed which is at fault (wiring, amp, source) after completion of the above procedures, the amp may require an internal look and see.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FIXYA.

My red protection light comes on and the amp stops if i turn up the volume on the head unit more than just a little. the settings on the amp are not more than half way up. all other lights are working....


sounds like you need a farat cap, your drawing more power than your cars gerating system and put out....does your stereo dim when the bass hits?

I have polk amp that is powering 2 12' subs but itis flashing up with low amp/short light with a little buzz noise?


you must check your wiring from head unit back to subs even take subs out of box to make sure no wires are lose 99.9 of the time a wire has come lose which can be bad if your bridging sups as it changes ohms with 1 or 2 subs hope that helps oh and check volts from you batt and check volts at fuse spots and after fuse to make sure your geting at least 12 to 14 volts cheers i just had a ***** of a prob my subs worked but **** bass found out head unit sub out craped out

Your probably not pusing enough wattage to the amp. Look into buying a capacitor for your set up. and you may need to run a thicker guage wire to your amp.

Most likely the RCA's are running from the sub out on the deck to the amp. You need to run two sets of RCA's for a 4 channel amp. One for the sub out and one to the front or rear channel.

Hope this helps.

Low ohms light flashes and bass distorts at high volume


Sounds like you need to invest in a capacitor. Those are used when subs receive a bass spike. You just a need a 1 Farat Capacitor (1,000 watts) ran between the head unit and the amplfiier to fix your issue. Also, try reducing the volume gain to half gain and low pass frequency to half gain; this will increase your clarity and make your amp less hot. This may fix it without a capacitor. Also find out what amprage your alternator is. Your alternator may not be designed to run the amplifier. Most alternators are 200 amps now if they are gold plated.

Hope this helps

What power cap do i need for my car audio


I would go with a 4 FARAT capacitor then you know your amp won't be dimming your lights or clipping your amplifier signal.

I would actually buy the kinetic capacitor from www.onlinecarstereo.com they rated at being 100 1 farat capacitors. Great buy since it's on sale for $200 with added shipping.. Otherwise the 4 farat is needed.

Power surge blowing fuses on amp when car is turned on.


the voltage regulator in the alternator or the capacitor is malfunctioning. get a multimeter on the battery when u start the car (before the capacitor) if it reads a large surge (something greater than 14 or 15 volts) then u may need a new amp, if not, then test it on the back end of capacitor to the chassie negative, see if u detect spike there.

My Orion 2500D amplifier turns off then back on at high volume


you need a # 4 gauge wire. check the subs conection no less than 1 ohm. check ground. and if the cap is good. 13.8 volts are for max ouput ......this is 1 ohm of charge at 13.8 volts they give 2500 watts butt only at 13.8 volts whit this relation. i¨n think you need other alternator. good look.
