The bigger the wire the better the resistance but even a wire wont do much
the only thick i have on my sterio is the battery wire the rest is cut old extension cord wires and mine sound fine never cut out on me and i have 1600 watts going threw amp

more power putting threw the hotter the amp hotter the amp more the cut off amp

quite possible you have too much power going to speakers if your bridged it will blow out amp found that out from bridgeing but thank god i had it fused

turn down your gain and bass boost and work up to good sound say your sterio is 1-60 volume your should hit right around 30 volume by turning gain and boost untill quality sound this is your safe zone gain should be set 1/2 volume of sterio to 3/4 pushing it nothing more or total melt down

My kicker 12 inch cvr's arent hitting as hard as they should


amps and wiring kits are very optimistic on the output. If you want proper wire, buy some welding cable "0" or "00" guage. That solves the power delivery. Put a 1 Farrad (or more) capacitor near the amp, that solves the surge power issue. Make sure the box is suitable for the subs. Lastly I'd say do some research and find the right amp that can deliver the clean, huge current required to move some serious air!

2 kicker cvr 12's in prewired kicker box with 1 wire terminal, kicker cx1200.1 amp. Whats the best way to wire this combo?


Well you really can't run both speakers on one term. because you will over heat the amp , unless your amp is rated at twice the capability of your subs , Then if so , Try positive to one sub , then neg. to the other sub , then bridge the remaining positive to the remaining negative terminal , But it is really best to get a two channel amp for your subs !!!

I have 2 12


To be on the safe side without further information I would hook the two subs up in series leaving you with an 8 ohm load.

I have 2 18" kicker


First you need the OHM rating of the subs. Most of the time its on the box or the magnet on the back of the subs (normaly 2ohm 4ohm or 8ohm) And that of the amp. Most amps are 4 ohm output if its a 2channel and 2ohm output if its a mono. You NEED to know these cuz wiring it wrong can blow channels in your amp or cause it to cut "in and out"

I have 2 15 inch L5 solo baric subs and need a amp?


the 15" l5 is rated at 750 watts rms so i suggest you get an amp with atleast that much power because if you get a amp weaker than that you run the risk of clipping your subs and blowing them

Busted Kicker Subs


hi not worth fixing as labor is to high.

look around on ebay make sure you replace them with a name brand some companies like JBL sell refurbished subs with full warranties for cheap.

Remember with subs you must have a crossover either electronic or just a component in the cabinet so that the speaker is only reproducing the correct frequencies.

Lastly 12" subs require a ton of clean power 200 watts per ch minimum..and if possible they should be either 1 channel amps or bridged to 1 channel meaning for a pair of 12's you would have 2 amps

Contrary to popular belief most subs are damaged because people overdrive their amps and that blows the voice coil

hope that helps

I have an Audiobahn A8000T amp and 2 12" Kicker CVR (DVC) Dual voice Coil. The Subwoofers are 2OHM a peice. What is the best way to hook this all up to run a 2 OHM load to my subs?


This is a link to Kicker for your CVR12 Subs...if you have the 2 ohm version (2 ohms per voice coil) and you have 2 speakers ....you will need to wire EACH speakers voice coils in series to get 4 ohms from each speaker and then wire the 2 speakers in parallel.....as in....2 ohms in series with 2 ohms = 4 ohms....both speakers wired same way, then in Parallel with each other = 2 ohm load. Page 2 of this link gives examples of both series and parallel wiring of your speaker.

If you are still not sure as to my description of ' How To',
PLEASE respond and I will attempt to explain it EXACTLY via wiring directions.

I have 2 alpine r type 12's hooked up to a kicker crossover and a NRG 2200 800 watt amp. they are wired series and parallel. when i turn it up the subs sound like the are fluttering. what is going on.


well my friend either your amp is not powerful enough to push your subs or you have a sub that is shorting out cause i just had the same problem with my 2 15 kicker cvr competition subs

How do you wire four 12 inch kicker cvr dual voice coil, to a 2400 watt 1 channel class d amp


Hello brysonford00,

The wiring configuration depends on what final impedance you want the amp to see. If the subs are 4ohm DVC's, you can wire them to present a 2ohm impedance or an 8ohm impedance. The diagrams are here. If your subs are 2ohm DVC's, the wiring is the same. The impedances will be 1ohm and 4ohms.

Hope this helps.

huge shared common space slot loaded box (size depends on sub 10", 12" 15" you need to clarify that please) the amp specs on earthquakes site say the phd5000 is rated at a max output of 5k watts at 1 ohm 3k watts at 2 ohm so, with 3 dvc 2 ohm subs you only have 3 options of which only 2 will be a usable solution:

1. 3- 2ohm dvc series at sub parralel at amp = about 1.33 ohms at the amplifier this is the best option to get the most power to the subs as each sub will produce a 4 ohm load then wire each one to the amp the amp sees 3 4 ohm parralel loads which = 1.33 ohm so based on the amp specs you would be close to 1200 watts per sub.

2. 3- 2ohm dvc wired in series at sub and all 3 subs series wired together very difficult to wireand will give you a 12 ohm load which is next to no power at all (not a viable solution)

3. 2- 2ohm dvc parralel wired to each other and then at amp the amp sees a 1 ohm load and makes 5k watts max but you can only (REREAD THAT LINE! ONLY USE 2 SUBS IN THIS WAY) WHICH GIVES THE MOST POWER BUT ONLY USES 2 SUBS
