Which will hit harded 2 ohm or 4 ohm - Kicker CVR15-2 Car Subwoofer

First make sure everything is wired correctly, correct polarity and channels. If the amp is a 2/4 channel and 800 watts @ 2ohms, then you would wire your dual voice coil sub at 2 ohms to match the amps output. Same thing if your amp was at 4 ohms, it all depends on how you wire it. Now if your running door speakers off the amp then I would put in an equalizer to better tune it and make sure the amp is set at the proper channels with correct polarity. Double check to make sure your ground,power, and remote wire are getting a good connection

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!

The ohms rating measures the electrical resistance of the subs(impedance). On the subs there is usually a label that tells you what the impedance is for that particular sub,example= 4 ohms . The only way you can get to a 1 ohm load or less with a pair of tens is if each sub has dual voice coils that are 4 ohms each wired in parallel. Generally Sony xplod's are a single coil 4 ohm woofer-yours might be the exception in this case .To figure out your resistance say with 2 subs that are 4 ohms you have to know how you intend to wire them for instance if your amp puts out a fair amount of power @2 ohms and thats the number you want to hit than you will want to wire the subs in parallel( + to + and - to -) wiring in parallel lowers the resistance.(ohms) If you want to hit 1 ohm and you have dual 4 ohm coils then wire all 4 coils in parallel and that will then be a 1 ohm load. Its simply a matter of dividing the ohms by the number of speakers that you intend to connect. if you had 3 10s that were 4 ohms each and you wired them in parallel the ohms would be 1.33 (as 4 divided by 3 is 1.33)(4 divided by 2 is 2) (4 divided by 4 is 1) On the flip side wiring in series will raise your impedance-a pair of 4 ohm subs wired in series gives you an 8 ohm load 3 subs gives you 12 ohms and so on. I wouldnt worry about the high current switch unless youre planning on taking it down below 1 ohm which it sounds like you arent currently set up for.

it depends on the impedance of the subs-if your subs are dual 4 ohm coils then you can parallel the coils which will give you 2 ohms per sub- you could get max performance from your amp by just wiring the 2 ohm speaker load to each channel of the amp which will hit them with about 200 watts rms each. another way to do it is to wire the coils in series which will make each sub an 8 ohm load and then parallel them together and that will show a 4 ohm load -which you can use to run the amp safely in bridged mode. This will give you exactly the same amount of power to your subs as in 2 ohm stereo will. so with your amp being 2 ohm stable in stereo or 4 ohm stable in bridged mode- those are the numbers you want to hit for maximum"safe" operation

are you factoring the ohm rating from running them parallel?

2 x 2o subs parallel = 0.5 ohm (lowers ohm's)

2x 2oh subs series = 4 ohm

IT is posable that you are calculating the ohm rating fine, BUT some SUBS can reach lower ohm rating while hitting bass- i didnt know this till i had a rather insane sub that would dip to 1ohm while hitting hard bass causing my amp to go into protect mode.

comp VR 15s are rated @ 500W RMS 1000Peak.
The lanzar vibe amplifier is 2 x 600W RMS at 4 OHMS 2 x 1200W MAX at 4 OHMS 1 x 2400W MAX at 4 OHMS Bridged 2 x 1000W at 2 OHMS RMS.
Your subs are single 4 ohm subs.
If your subs are wired stereo, they both are seeing 600W. (more than the rated RMS)
Chances are, you have them wired parallel to a 2 ohm mono load - of which that amplifier is not rated. In theory, it will produce about 2000W @ 2 ohm mono for a short period of time.
Your amplifier is too powerful for your subs. Turn down the gain setting to 3/4 or purchase better subs. Also be sur the subs are inthe proper enclosure. It sounds as if they are excurting past their linear x-max and colliding with the rear bump plate. This will cause damage down the road if left as is.

You've pretty much hit the nail on the head. Two 2 ohm subs in parallel would give you 1 ohm, and two 2 ohm subs in series would give you 4 ohms. 1 ohm would be overloading the amp but 4 ohms is slightly "underloading" the amp.

Your best solution with the gear you have (i.e. not buying new subs or a new amp) is to put the subs in series (4 ohms). True, you'll be putting about 200W into each sub, but according to page 4 of the owner's manual for the subs, 200W is just a tad under the optimum level recommended for the sub anyway.

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

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.

did you read your instruction manual. does it says "it could be bridged to other amp"?. you can't make a bridge to amplifier that is not bridgeable. bridging an amp is a way which it is made through transistor type ampilfier by bridging more transistor inside and more voltage is required for bridging.
I don't know if we could do to an IC type amplifier. ask an experts about bridging IC types how to bridge maybe they know how.
and if you had an successful bridging, you may have a problem through your speakers, they may hit hard but you will experience some errors through your speakers and easy to worn.
