A number of things could be wrong. First off, how do you have the 3 subs wired that will actually give you 2 ohms? For instance, if you had 3 single voice coils and they were each 4 ohms You would be sitting around 1.5 ohms. Or if they were dual 4 ohm subs then you could have wired the voice coils in series then the subs in parallel and came up with about 3 ohms. Unless the kickers have an odd impedence then there is no way you have 2 ohms from the subs to match the 2 ohms at the amp. So what I would do is try to match the impedence as well as I could. Also, make sure the amp is well ventilated. do not screw it directly down to a surface, put some 1/4" spacers on the screws so some air flow can get under the amp also. I hope I could help. Good luck

I have 2 10" Kicker Comp Subs


That amplifier is only rated at 150 watts at 4 ohms, or 300 watts at 2 ohms. Not a very strong amp to run 2 kicker comps. My guess is you have the subs wired wrong for your application. There are 2 types of subs, one is a dual 4 ohm, and one is a dual 2 ohm. Most people bridge these coils together and that cuts your ohms in half. For example. Lets say you have the 10cvr104 subs. Thats the dual 4 ohm sub. You wire the coils together in parallel, now its a 2 ohm sub. You have 2 of these subs running off of your amp, if they are hooked up in parallel, now you have a 1 ohm load, out of the amplifiers normal operation. Your amplifiers internals heat up really quick and there is a thermal overload, putting your amplifier into circuit protection mode. My suggestion for wiring your subs is as follows: for each speaker, wire the coils together like this- positive coil1 to negative coil 2 and negative coil 1 to positive coil 2. That is called running in series, and doubles your ohm load. Next, we need to wire the speakers together properly to hook up to your amplifier. For this, since the coils are hooked together, you only need to use one set of terminals from each sub. And take the positive from sub 1 and hook it to positive of amp. Take negative sub 1 and hook it to positive of sub 2. Take negative of sub 2 and hook it to negative of amp.

My system is running hot!!!!!


your subs are the problem, not your amp, your wiring your subs paralelle, means dropping input ohmage, allowing your amp to over heat with minimal load, check the amp specs for running at low ohms, most hifonics amps are rated 2 ohms and higher, some however will run at 1 ohm, only on class b-a amps though.(competition) dropping ohmage will allow the amp to push more power to the voice coils, however the voice coils may not be rated for 1 ohm power, what ohmage are your coils rated at? do you have a min. of 100 amp inline fuse on your 1-0 awg wire? do you have internal fans? you can add mosfets to the amp but if you do so, you'll have to re-program your amps mother board.

Sub Wiring


Hello jtkpay,

Rockford-Fosgate claims their latest V-power 1500bd is stable to 1 ohm, and I would think that your Oldschool would also be. The 2 wiring options for 3 subs with 2 ohm dvc would give you a 1.34 ohm load and a 3 ohm load. The 1.34 ohm option would mean more watts to the subs, but the amp will run hotter. The diagrams look like this:

Using just 2 of the Kickers, you can wire 3 different ways, with final impedances of 0.5 ohms, 2 ohms, or 8 ohms. You do not want the 0.5 ohm load. It's bad for the amp. You don't want the 8 ohm load. It doesn't allow the amp to produce as much power. So that leaves only the 2 ohm, with coils in series and subs in parallel. It looks like this:

Hope this helps. If it does, please rate as "FixYa".

Amp burning speakers.


one of the channels your using may be burned out or there is sum wire touching inside the amp so take the cover off and make sure nuthn is touching and see if sumthn is burnt and also try using a different channel on the sub

Nedd help kicker kx1200


it should power them fine but you will have to make sure you do not wire them where the ohmn load is below what the amp is stable at most of the are 2ohmn stable you can use a mutimeter in the ohmns setting to determin this

How to hook up 2 10 inch speakers


For best results the output resistance of the amplifier must equal the combined resistance of the speakers. So if the amps says 8 ohms and you have two 4 ohm speakers you put them is series or if the amps says 4ohms and you have two 8 ohm speakers put them in series. If it says 4ohm and you have two 4 ohm speakers best to use only one. It Depends on the output resistance of the amps. It is usually written at the terminals where the speakers are connected.

My kicker amp turns off


It sounds like you may have the load impedance too low. How many voice coils per woofer? How many ohms is each coil? If you have DVC woofers, are the coils for each woofer wired in series or parallel? Are the speakers wired in series or parallel. Let me know if you need me to clarify anything.

Overheating


The Kicker 10 may be running a 1 ohm load and that amp isn't 1 ohm stable.
