I have a kicker dx 500.1 amp and a kicker cvr12 sub. When I first hooked up worked perfect for a few minuted. Adjusted settings ont the side and it went out. Now When I power on it the protection light...

check the fuse on the power wire (+) not the ground wire .. i had a kicker 1500.1 on 2 l7 15\'s and when the bass would hit hard the fuse would vibrate and cause the amp to go into safe mode.. after re wireing the whole truck i then found out it was the 150amp fuse holder

I have a 500/1 mono jl audio amp and two w3 10" woofers, every time my bass hits hard my low ohm light will flicker on and off but the light doesn't stay on to long it only flickers every time the bass...

not really a problem, your just running a the threshold of the amps comfort zone, a lil trick to raise your impedance a little bit its to run an additional 10 feet of wire before your sub, (longer the wire the more resistance) 10 feet should jump you up about .5 ohms. you wont hear the difference but your amp will fill it, and run a little better. 20 feet will give you right around 1 ohm. now if you dont mind loosing some power run the subs in series and then run them bridged. your amp will work harder, but run easier because its on a big open loop. but before all this take a multi meet and read out your voice coils to see what the ohm level is, then read out what it is at the speaker, then you will see 1. if the subs are okay, and 2. how much you need to raise your impedance for you amp to run comfortably.

I have an alpine type rs one is a1542 and one is 1522 how can I make them hit the same or can I ?

I dont think it matters but it is not really a good idea to have two different subs in one box (if they are). They need to be in phase. They have to have the same amp is running them with corrects wattage and impedance, ya they can hit the same. The subs are so much the same i really dont think it matters if they are in the same box.

My system just stopped working one random day. the sub will hit very softly every 5- 10 seconds. i think it is the amp. what could it be?


Well my first thought is that you blew your sub. Does your amp have a power light on ? Is it green or red ?

If you have an extra sub or amp, or a friend does. Try switching one or the other out (sub would be easiest) and rule out which one is really at fault. But im still leaning towards a blown sub.

Post back if you have any further question's or comments. Thank you for choosing Fixya!

10 inch subs need help

It sounds like the wiring either to the amp or to the subs is put together wrong. This can be because you have them setup in stereo but have the sub on bridge mode or vica versa. This can also be from how you ran the audio input wither from speakers or rca..either wired wrong or the switch for the two options is wrong. Also make sure your gain is turned up. Sound also depends on what kind of box it is in. It HAS to be in a box.

My car AMP will play for a few minutes, then just Turn OFF

Is your sub single voice coil or dual? If it's dual, is it wired in paralel or series? It's possible for an amp the heat up so fast, the outside is not hot to the touch. Also, the next time it happens, use a paperclip and short the 12+ to the remote wire on the amp and see if it comes on. Let me know, and be sure to leave feedback or I don't get paid

Flickering power light

Does your amp get hot enough to cook an egg on?? Because I had this same problem but it wasn't a good make amp, and what the actual problem was is that the amp was not big enough to support the sub I had on it! Check the heat of the amp and maybe move it to a place where it gets more air and also check the watts on your sub and the power output on your amp.
