My amp wont power both subs the same

I run my Kenwood KFC-W3009 from a Tornado 5 channel amp via a cross over . Amp is 2000w 4 channels are for the 6X9's & the 5th channel is only for sub. I will never sell that amp as i kicks. I use it in my 15 seater bus & people can hear me coming down the road

No to be jerky but, bring it back to the "professional Installer".

the problem sounds like your new sub is drawing to much power and your amp can not handle it. bridging the amp is a good way to get the full power out of your amp. But it isnt always suggested, my solution is to get a bigger amp. I install stereo systems for a living, and i tell my customers that it is smart to get an amp about 100 more watts then the rms rating of your subwoofer.

Its hard to tell what you can or cant do without knowing exactly which kenwood amp you are using. Generally speaking though most kenwood amps are stable only down to 2 ohms. you will be better off just using 2 of your 12s wired in parallel- that will give you a 2 ohm load. There is a way to use all 3 simply by wiring them in series, it will end up giving you a 12 ohm load on the amp though which will work fine but you wont ever achieve the full power that the amp can do.

Does the amp have an input 'clipping' LED? The worst thing for a speaker is to try and reproduce an unclean signal. Just make sure not to overdrive the amps input. You might also purchase higher rms rated speakers. As far as the ground is concerned, paint and/or oil, rust etc have been cleared from contact area, correct? Seems like if ground were insuffecient, power to amp would drop out.

find the rms rating of the sub and compare it to the amp.if the rms of the amp is higher than the sub you have enough power to push the sub.if its lower look at the rms of the amp if it can be bridged.you would like to see the rms matched to the sub or subs if you have enough power.

Hello again debrahood196,

Your KAC-5204 amp is only rated to put out 60 watts per channel and really cannot push very hard. If your subs are the KFC-W110S, they are 8ohm subs and you will get better power from the amp by using the bridged connections, positive (+) on the left channel and negative (-) on the right channel. Wire both positives and both negatives from both subs to the bridged connections and the output will be 150 watts into 4ohms. Giving each sub 75 watts should make them push a little harder.

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.

your only choice is to run the amplifier at a 4 ohm mono load - this will not reult in the amplifier making much power.
Positive on sub to Positive on amp.
Negative on sub to Negative on amp.
This is your only possibility.

Adding a second sub in the same fashion will result in a 2 ohm load, and your amplifier will run at its rated potential.
