BASS COMES IN AND OUT

I HAVE 2 1500.1 AMPS PUSHING 4 CVX 2 OHM SPEAKER THE AMPS ARE UP A 1/4 OF THE WAY UP AND WHEN THE BASS HITS IT WILL HIT HARD AND THEN SOFT AND ON 1 OF THE AMPS THE GREEN LIGHT DIMS OUT AND IN. I ALSO ALREADY HAVE A BACK UP BATTERY

Check your ground wire and make sure it is on bare metal, no paint or rust or anything that could get in the way. also check to make sure you have a good power connection. thats all i can help you with. hope it works.

When I turn the sound up and the bass hits hard the red light comes on


That is because your impedance is not correct. You probly have 4 ohm woofers wired in parallel. Try putting them in series. That will put your impedance to 8 ohms the amp will not clip, or go in protection that is what the red light means. Good luck

How do I connect my nitro 1000 watt amp to get thr most bass .i have two 15 vx kickers


If you have the Nitro bmw-482 running it at 2 ohms will give you the max output (its not 1ohm stable so don't run it that way). First run your two dvc speakers parallel (run both negative out puts together and both positive out puts together on each speaker). After this you should have 1 positive and 1 negative wire from each speaker (4 wires altogehter). This will give you a 1 ohm load which your amp can't handle, so you have to run the 4 wires in series to create a 2 ohm load. Now take the positive wire from 1 speaker and connect it to the negative wire from the opposite speaker. Thats how to run in series. Now you should have 1 positive wire from 1 speaker and 1 negative wire from the other speaker which is 2 ohm load. Your amp sould be bridgeable, so connect the positive wire into the correct terminal of your amp and the negative wire into the correct terminal of your amp according to where to bridge it (positive into left positive, negative into right negative) . That will give you a 2 ohm load bridged which is the most power you can get out of your amp 300 watts. Medium quality amps are over rated so you will never acheive the 1000 watts as advertised.

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 two type-rs hooked up to a mrp-m1000 and its not hitting hard at all! but when one is hooked up it hits harder than two... so is it the way its hooked up or do i need another mrp-m1000 amp? or can i...


If the speakers are rated at 500W or greater, then you'll need two amps to get their full potential. When you connect two to a single 500W amp, each speaker only gets a max of 250W. Also, check the ohm rating for the outputs of the amp and the ohm rating of the speakers as well. Unmatches speaker/amp impendence also results in poor performance. If you connect two speakers to one terminal, the total impedence of the speakers falls by 1/2 (two 4 ohm speakers wire together will result in 2 ohm impedence). So, if you have an amp rated at 4 ohms, you could connect two 8 ohm speakers to a single output. Hope this helps some!

I have a kicker 750.1 amplifier. I was playing it one day pretty loud and it cut out once the bass hit and started smoking.The gain was up about 1/4 and the bass boost was about half way. what could of...


I would say that your subwoofer Or speaker leads have shorted out...when the bass hits as you say it drives the amp hard but if it is trying to dump power onto a shorted speaker or speaker wires it will blow the output power transistors not to mention other vital components of the power amp...i suggest you test your speaker leads with a Multimeter on the ohm setting before connecting a repaires or another amp.. to make sure there is no short on the leads and that the resistance is around 4 ohms or so depending on how you have your drivers wired...but anything lower than 2 ohms will cook an amp! you can normally pick up a meter from anywhere for around $10..

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

Sony xplod xm-1652z amp


You probably have the output bridged at 2 ohms. This amp is not a 2 ohm bridged stable amp. It is 2 ohm stable only in stereo. That means each channel can be 2 ohms, buts not bridged at 2 ohms.

If you have two 4 ohm speakers that are wired in parallel and then you bridge them, you have a 2 ohm load.

They only safe way to use two 4 ohm speakers is to run one speaker to each channel and then you have a stereo 4 ohm load.

When you use a 2 ohm load you get twice the current draw thru the amplifier as you would with a 4 ohm load. That means that the fuse you are using, the rating the amplifier is designed for, will blow any time you have a big bass hit.

If you are not using a 2 ohm bridged load, and you are using a 4 ohm bridged or something the amplifier is rated for, and you still have this problem, you may have a bad speaker. Even a speaker that will play can sometimes be on the brink of shorting out and causing the amplifier to draw lots more current than it is rated for.

If this is the case, you should go and get your speakers checked and see if they are still measuring at 4 ohms or at least close to it. Most speakers will measure a little lower than what the are rated. It is not unusual for a 4 ohm speaker to measure at 3.5 ohms, but if it is less than that, you problem is the speaker. Even if the speaker still plays.

I hope this was helpful for you, if you require any further help just ask.

If you did find that this was helpful in solving your problem, I would really appreciate a good rating.
Thanks and have a great day,
Dave

Overcurrent comes on when i turn up the volume on my head unit


The over-current LED tells you that you're driving a lod lower than the amp is rated to drive. You either have the wrong speaker ohm load, a shorted wire or a defective speaker.

Car Audio System Drwing too much power with 2 different Amps


A dual voice coil speaker can be wired to be a 2 ohm speaker or an 8 ohm speaker depending on whether you wire it in series (8 ohm) or parallel (2 ohm). When you bridge your amp then the two channels will share the load from your speaker. If the speaker is wired as 8 ohm then each channel of the amp is driving a 4 ohm load which is fine. If you are bridged into a 2 ohm speaker then each channel will be driving a 1 ohm load, which is a very very heavy load. Is your amp designed to drive a 1 ohm load? If not then that would explain why you are having a problem.
