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

I have two kicker cvrs 2003 model wired at a 2 ohm load, one

Sounds like the sub is blown. Swap the two subs and see if the sound comes from the other sub in the original location as well. If not, then you have a bad sub. If the bad sound happens with both subs then you need to look at wiring and the Amp.

My friend jus bought 2 10 inch kicker l5s and when we hooked them up to his boss 1100 wat amp and hooked everything up they are moving but are not producing any sound. boss amp i do not know any thinbg...

it must be reversed polarity in coil voices of speakers check + - wires from amplifiers fit on coil voices of speakers try to get each speaker to 8 ohms wiring in serial the two coil voices n'd put in paralel both speakers in bridge mode output from amplifier to get most stable power ,

I have a brand new L7 is it blown?

check to make sure your box is securely sealed and that the box itself is not rattling. if not, most subs require a break in period where they can not be played full gain/full volume for the first 48 or so hours... did you break in your subs by paying it softly the first day and slowly turning your amps gain and receivers volume up the next couple of days. if not, it is likely blown

2 10 kickers not playing. . .

Hello zqueliz,

It's possible that the sub is blown, but it may be something else. You did not specify how the subs are wired to the amp, how many channels on the amp, or whether or not the CVR's are in separate enclosures. These specifics will affect how you isolate the problem.

1) Check all of the wiring: RCA's from head unit to amp, speaker wiring from amp to sub. Make sure there are no breaks in the insulation and that the wire does not come in contact with another wire or metal parts on the vehicle.
2) Remove the nonworking sub from the enclosure and check the wiring from sub to terminal inside. While you have the sub out, check the "braided" wires going from the sub terminals to the cone.
3) Reverse the wiring from the amp to the subs to see if the problem moves to the right sub. That will tell you the problem is not in the sub.
4) If the left sub still fails with the amp channels flipped, you find no wiring defects, and you can't see any physical damage, test the sub voice coil with a multimeter. Set the meter to read "ohms" on the lowest scale. The actual reading should be a little less than the rated impedance. If the subs are 4 ohm, the meter should read about 2-3 ohms. If the meter reads "0" (pegs) or if it reads "infinity" (no reading at all), the sub voice coil is bad.

Hope this helps.

Solo x 10 dual 2 ohm smells burnt and smoke

there is no such speaker as a solo-X L5.
The Solobaric L5 is 450Watts RMS and 900 Peak.
Check your documentation, and no warranty except Massive Audio covers Burned Voicecoils as it is deemed customer abuse.
If it is a typo, and not an L5, your combination (as long as each is level matched) should be ok to run on that sub. When wiring it as you describe, the two amplifiers need to be identically matched in order for both coils to play at the same level.
Seek professional installations so your warranty is intact.
