I have a kenwood KAC-9103D amp pushing 2 jl audio W3 4 ohms speakers. The amp is 500Wx1 RMS. One of my subs just stopped working. I wired it just like the JL website and amp manual explained. The subs worked great for a year. I've checked all the wiring and nothing is lose and the fuses are good. both channels in the amp are good because I checked it with the other sub. can anyone explain?
You have too much power. Although the power is 250 watts a piece. you should never apply the full strength of what the speaker is made for; and if you do the reliability of your speaker will deminish. Hense only one year in your case.

Remember that that amp is one ohm stable so you will not be getting the most out of that amp with that subs set up. The subs will only see 650 to 850 watts total...so each sub will only see about 215 - 275 watts a piece. Find out what the RMS wattage of your subs are each an determine if the wattage I mentioned above meets those requirements.
Choosing a amp isn't always easy but it first begins with what you want.
--RMS of the speakers is what you want to use to find your amp. That's going to tell you what watt's your speakers can REALLY handle @ 4 ohms. --Also what you want to spend $$$ will determine how clear it sounds. --I prefer a Rockford Fosgate amp for base and kenwood for highs. --Also look at the RMS watt's rating to find the proper power and go a bit beyond what you want so that the amp performs with ease. --Last but not least you chose the amp for how many speakers you are going to connect to that amp. For example if you are using 2 JL audio 12" for subs, then a mono amp is perfect. But if you are connecting 4 speakers, you should begin to find the amp with four channels so that you obtain left, right , front and rear sound.
if you get the 4ohm you can wire it to run a 2ohm an the kenwood amp will push 900 watts at 2ohms.they say it can push up to 1800 watts,that would be at 1ohm.that kenwood runs 500 at 4ohms an 900 at 2ohm.if you need help wiring the sub or anything else let me know bertman285@hotmail,com
Max Power Output
4 Ohm [14.4V]
500W x 1 [20-200Hz, 0.5%THD]
2 Ohm [14.4V]
900W x 1 [100Hz, 1.1%THD]
Having your subs in well-designed and constructed enclosures will make as much or more difference in their output than how you connect them to an amp.
The TS-SW1241D's are single voice coil 4 ohm shallow subwoofers that are rated for 350 watts RMS. For maximum loudness, your JL amp needs to be 2 ohm stable and capable of delivering 700 watts RMS into that impedance. Wire the subs in parallel for a 2 ohm load and maximum power from the amp.
It can but it'd be a waste for your subs. 1 of those by itself will handle that amp. it'll push them just not really hard, i'd recommend an upgrade to a 1100-1200 watt rms amp if you're gonna run 2 cvx's. if you only run one sub that amp'll work well...
Hi firstof all your deck isnt really putting out 52 watts x4 more like 17-22w rmsx4 ,companies like to throw out some crazy numbers it seems. If your into Kenwood try out a KAC-8404 4-channel on the mids/highs that will put 50 w x4 rms at 4 ohms or if you wanna go a lil louder try the kenwood x600f that will throw 100w rms on each 6x9 at 4 ohms no problem. My system is very similar to yours but running 4 pioneer 5x7's in all the doors and powering it with the 8404 its loud and clean ,fan cooled and no problems at all. My subs are a pair of 15's soundstream t-4's powered by an Alphasonik pma2500a its throwing 800w rms on each sub running in stereo at 2 ohms.It can drown out the mids if i set it that way but my mids /highs cant take as much power as your kenwoods can or else id step up to the x600f too.
So I am assuming that you have just setup/wired this up recently? Have you had this working before? You can have a look at the gain control on the amp & see if this have been set really low. This will help if the signal coming from your stereo is weak. The other thing I would suggest is to make sure that the amp can actually push this sub. I know what the specs say:
Remote gain control, mounting hardware & screws included
but I don't believe most of these. Many manufacturers embellish what their products can actually do! With the bigger more established brands such as JL Audio you will have no problems, their products have been tried & tested so much on the competition circuit.
