I have a 4000 watt mojo on 4 12inch 4ohm kicker cvx.The amp keeps going into protect mode as the bass deeping,whats the problem.

If you connected speakers in parallel then two speakers have combined resistance of 2 ohms. You need to connect speakers in series

Are your subwoofers wired in series or parallel? Check your connections, if everything is ok, the problem is with your amplifier. It might have a blown capacitor inside or its not really a 1ohm stable amplifier. Have it repaired if thats the case.

check speakers impedance are matching amps. example: if you drive a 4 ohm amp with lower imp you are close to blow your amp or it goes to protect itself from you. anyway your amp provides 140watts maximum on 4ohm in bridged mode, so if you connect two 12" kickers with 4ohm, they will have 2ohm in parallel connection. solution would be to connect them in row (serial) but impedance will go up to 8ohms then.

Thanks for using FixYa - a 4 THUMBS UP rating is appreciated for answering your FREE question.

It can but it'd be a waste for your subs. 1 of those by itself will handle that amp. it'll push them just not really hard, i'd recommend an upgrade to a 1100-1200 watt rms amp if you're gonna run 2 cvx's. if you only run one sub that amp'll work well...

Hello rigo11785,

The MTX Thunder 1501D is stable at 1ohm and outputs 1,500 watts RMS into that impedance. An L7 with 2ohm DVC's would present a 1ohm load if wired in parallel and would allow the amp to produce more power than into the 4ohm series load. The problem is that the L7's maximum power handling rating is only 1,000 watts RMS, so if you wire the coils in parallel, you'll very likely overdrive the sub and perhaps damage it. Now, if you bought another L7 and ran the voice coils in series and the subs in parallel, that would be a 2ohm load and well within their power handling capability.

With that amp and sub, I'd recommend leaving the voice coils in series.

Hope this helps.

make sure the impedance is right for the amp you're using. If you're using a 4ohm amp and a 2ohm sud that may be the problem. It may be overdriving the amplifer which is bad and can cause damage to the amp. Hope this helps.

its a good amp but dont power ur amp at full put it at about half power

Hello storres18,

If you have the Kicker model number 06CVX122, with dual 2ohm voice coils, they can be connected to a mono amp at 2ohms. First jumper the voice coils in series, the dotted positive (+) to the undotted negative (-) (or vice versa). Each sub is now 4ohms. Then wire both of the remaining positives and negatives together on the amp terminals (in parallel). The amp sees a 2ohm load. Here's the diagram:


If you have the Kicker model number 06CVX124 with dual 4ohm voice coils, they cannot be wired to present a 2ohm load. They can only be wired as a 1ohm load (too low for the amp) or as a 4ohm load (at reduced power). Here is the diagram of the 4ohm wiring:


Hope this helps.

Hello,

It depends on the specific subs and exactly what you want out of them. You have practically unlimited choices for amps.

The 10" L7 has a power range of from 30-600 watts RMS, the 12" from 50-750 watts, and the 15" from 100-1000 watts.

So if you have the 10's, you would want an amp that puts out at least 90 watts RMS and not more that 1,800. Unless you are really into SPL and have an unlimited budget, it's probably best to go somewhere in between.

Keep in mind that these Kickers need to be in a proper enclosure. They like a little more volume to work as compared to RF's or MTX's and some others.

Does it shut off for a couple of minutes or a couple of seconds? Is the amp hot when it shuts off? Are you sure you have the speakers wired to an acceptable ohm load for the amp? Have you measured the voltage at the amp (across the B+ and ground terminals) to make sure it's not dropping too low on hard bass notes?
