Re: installation

Hi JJerky,

I suggest we go for 2 ohm to preserve the amp and not heat things up so bad.
Your Subs are Dual Voice Coil(DVC) and 2 ohms each coil. I am going to tell you the wiring to insure you get balanced response from both Subs. We will wire the Subs Voice coils in Parallel to make them 1 ohm each. Then we will wire the Amp to the subs in series to make the total load on the amp 2 ohms. When you have series to both subs each sub gets the same current.

Example of my coding :SUB1VC1+ = Subwoofer 1 Voice Coil 1 Postive terminal.

SUB1VC1+ to SUB1VC2+
SUB1VC1 - to SUB1VC2-

SUB2VC1 + to SUB2VC2 +
SUB2VC1 - to SUB2VC2 -

AMP + to SUB1VC1 +
SUB1VC1 - to SUB2VC1 +
SUB2VC1 - to AMP -

This should give you a good repsonse.

Adjust your Bass Gain down very low at first. Also cut you LPF to about 60 hz. Crank up the volume on a bass test Audio track, Adjust the Bass Gain up unitl you get distortion. The turn it back a little. This is proper setting for your Gain.

I have 2 12 inch kicker rt dual 2 ohm subs. On a kicker cx1200.1 i want to kno how to hook it up to 2ohm to the amp. And if i can add another 10 inch kicker rt 2ohm sub in the future.

Do to the impedance Of your sub u can't run it @2ohms its going to either be @1ohm or 4ohms and your amp isn't 1ohm stable and u will risk damaging your amp. So your only option is to run it @4ohms and on a good note your sub is 100-600 watts RMS and your amp will push 400-500 watts RMS @4ohms. Now if you want to run 2 sub's in the future That amp will work perfect because it pushes 1,200watts RMS @2ohms and to wire your 2 sub's @1ohm just follow the steps in the image below. Hope this helped.25345194-v0hbouy2nvquqteoroa5j5rq-3-0.png

Im trying to figure out how i should wire my Kicker S12L5 sub to my Kicker Zr360 amp. should i wire it for 1ohm and bridge it or what if you could help it would be much appreciated thanks. ...

What is the wattage of the sub? What is the power output of the amp, bridged & not bridged? If the bridged power output will NOT exceed the rated power of the sub then you should bridge it. If it will exceed the rated power of the sub then don't. 8)

I have an alpine type r how do i connect it i have all amp an everything hoked up but i dont know how to connect the sub since it has 2 red and 2 black

On just the speaker itself, hook up a short wire going from red to red, then hook up another short wire going from black to black... Then put one wire in either black slot and one wire in either red slot to wire to your box.... That is the easiest way... But if you are interested in other methods I will post a link... How you wire will change the OHMS, so depending on what model sub you have and what amp you have, going to 1ohm may not be safe for your amp if your amp is NOT 1ohm stable.

I have my l7 solo baric on series mode they sund

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.

Need to wire two dvc 15 in kicer l7 to 1 ohm

Hello goldy6569,

To wire the L72's at 1ohm, simply connect both +'s and -"s on each sub together. Then connect to your amp terminals.

With 2ohm DVC's, you can have either a 1ohm load or a 4ohm load. The diagrams are here (I know it's the website of a Kicker competitor, but their "wiring wizard" is simply the best).

Hope this helps.

Whats the best way to hook up my L7 10''

Hello ereza25,

The best way depends on what amp you are using to power the sub. With dual 2ohm voice coils, you can wire to either a 1ohm or a 4ohm final load. If you are sure that your amp is stable down to 1ohm, that wiring will provide the best power to the sub. But if the amp is not rated at 1ohm (many aren't), then the 1ohm wiring will result in overheating and possible damage to your amp.

The wiring diagrams are here. Hope this helps.

Wiring hk12x2

Hello jose08042008,

Your sub has dual 2ohm voice coils and can be wired to present a final load to the amplifier of either 1ohm or 4ohms. Unless you have an amp that is stable at 1ohm (not many are), then you will want to use the 4ohm wiring. To wire for 4ohms, jumper the positive terminal of one voice coil to the negative of the other terminal, and connect the remaining positive and negative terminals to your amp. If you know for SURE that your amp is stable at 1ohm, you can connect both positives and both negatives together on the sub and then to the amp. But if the amp 1ohm stable, this will result in overheating, and/or going into "protection" mode, and/or damage to the amp.

Hope this helps.

I want to hook up my 2 quad coil woofers to a 1ohm amp but

I would look up "series" and "parallel" wiring on the net. Parallel will lower your ohms, which is good- especially for you since your amp is 1ohm. use 1 channel of your amp (unbridged...bridging an amp could increase output, but will Raise the ohms) connect the positive terminal with a wire that goes to the positive on your first sub, and from there, connect a wire from that same positive terminal to the positive terminal on your second sub. do the same thing with the neg. wire. This is called parallel wiring.

How to wire kenwood amp to kicker cvr 12"

How you wire it depends on how hard you want drive your amp. If your woofer runs 4ohm per coil I would wile it in series (amp +to sub +1 sub -1to sub +2 amp - to sub -2) then run it for a week and see if it has enough power. the lower your Impedance (the resistance load on the amp) the harder your amp works and more THD (noise) is produced. (Dclass amps aren't know for being clean to begin with) configured like this your amp will see 8ohms and sound the clean east. if this turns out to be not enough power wire it in parallel and double the output. wire amp + to sub +1 and +2 then amp - to sub -1 and -2.

A word to the wise... start with your volume very low and work up slowly most speakers will puk up the voice coil before the amp starts to get warmed up. you would hate to have to buy a new sub.

Have fun

You have 2 subs and 2 amps right?In that case make sure that the amps are capable of stable 1ohm load and also you'll need a lot of power and 4 gauge power cable for each amp with fuse of course.
Now....take one sub and connect the (-) with the (-) and the (+) with the (+).Now you have one (+) and one(-) to connect to the amp.Do the same with the other sub and you're ready to rock!!
