2nd voice coil blown

I purchased from Crutchfield a Kicker CVR 15" set of Subs about 4 months ago. Since having it I have experienced problems such as a rattling noise when playing. After taking it to an Audio/sterio store they informed me that it was the 2nd voice coil and it was blown because of a wire that had snapped and shorted it out. I can't find the warranty information and was wanting to know what process I should take in returning the damaged unit to have it replaced. Please let me know how to handle this problem.

Have you called crutchfield yet? The are pretty good with customer service and stand behind their company. If they protest, get loud, they will likely bend. I have dealt w/them for years.

I have 2 different subs in one box, a 12" MTX thunder and a 12" Kicker CVR. the kicker is a dual voice coil while the MTX I dont believe is. Can I use one amp for this set up? And how would it be wired?


im guessing both speakers are 4 ohms ..mtx 4ohms and kicker dual 4ohms..now if your amp can go down to 1 ohm wiring the kicker dual coils in parallel (2ohms) and the mtx connected together (4ohms) should leave you with a final impedance between 1 and 2 ohms ...i suggest you use one or get another

How to hook up the subs with dual voice coils


  1. Visit the following link: http://www.crutchfield.com/S-jXlGCwReN8E/learn/learningcenter/car/subwoofers_wiring.html
  2. Choose which column your amplifier falls under, then find the number of subs you have, followed by the voice coil configuration.

How do you hook up 2 15 inch cvr to 1 ohm


Hello juanelreypla,

If your CVR's have dual 2 ohm voice coils, they can only be wired for 0.5 ohm, 2 ohm, or 8 ohm final loads.

http://www.rockfordfosgate.com/rftech/woofer_wizard.asp?submitted=true&woofer_qty=2&woofer_imp=3

If they have dual 4 ohm voice coils, they can be wired to a final load of 1 ohm. Wire the voice coils in parallel and then parallel both subs. Like the diagram in Wiring Option #1 shown here.

Logic soundlab cpx1400 need to wire to a kicker cvr 15


Hello discrete01,

The Kicker model number 07CVR122 has dual 2 ohm voice coils, and can be wired for either 1 ohm or 4 ohms. Model number 07CVR124 has dual 4 ohm voice coils and can be wired for either 2 ohms or 8 ohms.

Kicker's wiring page is here: http://www.kicker.com/dvc_wiring

If you have the version with 2 ohm voice coils, you want to use the 2nd diagram for a final load of 4 ohms to the amp. The 1 ohm load is too low for the amp and will cause it to overheat and possibly fail. If you have the 4 ohm version, use the wiring shown in the 3rd diagram which is a perfect match for the amp.

Hope this helps.

How do you wire 4 kicker cvr dual voice coil 4ohms to a 1500.1 kicker mono block 1 channel amp, they sound distorted when i turn them up, how should i wire them?


Hello antjobe,

According to Kicker the 1500.1 is only stable to 2ohms. So you will want your 4 CVR's to present a 2ohm or higher impedance to the amp.

The best configuration would be to wire the voice coils in series (each sub 8ohms) and then parallel all of the subs to the amp (2ohms). Here's a link to the diagram.

Hope this helps.

I need to know how to bridge a a 4 ohm 15 inch sub down to1or2ohm


Hello solo7908,

With a single 4ohm DVC sub there are only two possible wiring solutions, parallel the voice coils for a final 2ohm load or series the voice coils for an 8ohm load. In your case, you want to wire them in parallel, both positives and both negatives connected to the amp terminals.

Here are the diagrams: (-) to (-) and then to the amp - (+) to (+) and then to the amp. Impedance = 2ohms.

Hope this helps.

Good price


Hello smoot_dog,

Well, you did not specify whether you have the 2 ohm or the 4 ohm versions of the L7 and that will impact your choice of amps. But with 8 voice coils and 4 subs to work with, you certainly have lots or potential configurations.

If your subs are the 4-ohm version, I would recommend the Alpine MRP-M1000. Currently it is on sale at www.crutchfield.com for $347.00. With this amp you'd wire the voice coils in parallel (2 ohms), wire each of the 2 pair of subs in series (4 ohms), and the resulting pairs parallel to the amp for a final load of 2 ohms.

If your subs are the 2-ohm version, I would recommend the Rockford-Fosgate Punch P1000-1bd which is stable at 1 ohm. Crutchfield sells it for $349.99. With the Punch and 2-ohm voice coils, you'd series the voice coils (4 ohms), parallel each pair of subs (2 ohms), and then parallel the resulting pairs to the amp for a final load of 1 ohm.

Either of these amps will provide an honest 250 watts RMS to each L7. They'll not only rock your vehicle, they'll rock the pavement.

Need to know how to wire 2 15 inch cvr to a zx1000.1 amp at 2 ohms


If they are 4 ohm single voice coil subs, just connect all the negatives together and then all the positives together. If they are DUAL vc's then need more info.

Hi yeahonda,

 

Your Kicker L7 Ohms may be too low for the MA Audio Mono block amp. The MA Audio Amp is probably 2 Ohm Stable. The kicker will either be 2 ohm or 4 ohm Dual voice coil.   To eliminate the low ohms as a possible threat to causing the map to go into Protect, Wire the kicker Voice Coils in Series.  This adds the ohms, so that you either have 4 or 8 ohms. 

I am using the following codes to show wiring. VC1+ stands for the Kicker  Subs Voice Coil #1 Postive post. AO+ is the MA audio Amp output positive.

 

AO+ to VC1+

VC1- to VC2+

VC2- to AO-

 

This shopuld give you 4 or 8 ohm depending on the 15" L7 setup.  Crutchfield does not carry the Kicker  L7 in 15" They do  have the L5 in 15".

 

If you know how to read a Volt Ohm Meter, set it to OHMs 20 and measure across VC1+ to VC1- and you should see between 1.5 and 5 ohms..  Do the Same with VC2+ to VC2-.  you should see the same voltage. Also read from the Voice coil metal housing to VC1+ , VC1-, VC2+, and VC2-. and you should not read any ohmage to the case. The meter should say OL, or -1.

Good luck.
