The amp is going into protect on the two channels powering the speakers. Turn down the gain on those two channels. You also may want to consider crossing over the speakers a little higher than they are now.
The rating on those speakers are way too high. 6.5's and 6x9's will take 50-100 clean watts tops before they start to break up.
The best solution to get it perfect is....unplug the subs. Turn the gain on the speaker channels all the way down. Then turn up the deck 80% as high as it will go. Play a song. Then increase the gain on the amp until the speakers are as load as they go without distortion. Shut off the car, replugg in the subs and do the same thing. Gain on sub channels all the way down, deck then to 80%, find a bass heavy song, then turn gain up until subs become distorted. If you do this procedure your speakers and subs will be "gain matched" to the proper levels.
Make sure your frequency is no higher than 80 on the low and 120 on the high. Check speaker polarity with a AA battery(Speaker pops out when polarity is correct) Make sure the speaker crossovers are working properly. Check your ohm load when you connect the speakers together with a multimeter at the amp. Ohms that are too low = heat. See what your amp is rated for. After all that, turn the gain down all the way, turn up the volume to 25-28 and readjust the gains
You just gotta get your gains set up right. Look Up "How To Set your Gains with a Multimeter" your over powering your subs or speakers and your amplifiers cant keep up. you also have to make sure your speakers are wired to the right ohms. your amp cant handle. if your amp cant handle, for Example:1 Ohms your gonna blow your amps. ......Speakers and subs are a science too.
To start, turn the gains on your amp all the way down. Bass boost should be off (this us used if you listen to your subs at low volume, the boost will heat your amp up quick if you use at high volume). Then turn the volume on your headunit up to 3/4 full. Make sure the filter on your amp is on low pass. The crossover point should be at it's lowest too. With all these in place, you can begin turning up the gain. You will have to decide at what point to move the crossover point. Since there are different styles of music, you will have to listen to where you feel notes are "dropping off" from the music. Adjust the crossover point to your liking, but remember that subs were made to reproduce low frequencies. Hope this helps
if they are 4 ohm dual voice coil wire them to 1ohm and bump do not turn gain all the way you will fry the amp and if you really want to make them kick . write each 1 to 2 ohms and get another amp they are not getting enough wattage for the volume you are trying to run them at and could be the way you have it tuned .
wire the subs if thair dual 4 ohm . in parallel. red to red and black to black. giving it a 2ohm load. do the other sub the same. and conect it on the amp . turn your gain about 12oclock and db level less than 12oclock and your frequnecy around 80-100. and that should work
Make sure to tune the amp according to the subs. Turn all the levels down on the amp, then start with turning up the gain till you can tell the sub is struggling, from there turn up the crossover to around 120hz. Then adjust the gain again as now it will prolly be to high. Also it depends on how you have the subs wired up.
kicker subs arnt ment to hit the lowest bass, unless you go spend a **** load of money, im talking 3000 wat amp, ant some 15' or bigger subs. the most commen kickers are 12' subs, so im asuming you have 12' subs, if not, this (said lightly) should work. try turning the bass boost screw on the amp to the middle of its turning range. this will offer the greatest balance between high and low bass. if you want more low bass, turn it past half. if you want more high bass, turn it down. i have mine set to mid range, but i also recently purchased 2 18' kickers. with every new set of subs, you should spend at least 15 min tuning the amp to get the best performance. every sub is different. hope this helps, good luck.
First check your gain it may be turned down. I personally dont bridge speakers. I put each speaker to its own channel on the amp.Make sure positive to positive and negative to negative. Try hookin up two speakers to the amp (not bridged) and turn your gain up around half way. Make sure you amp is switch to lowpass not high since most amps have crossovers built in now. The more speakers you have the less output from each speaker from one amp youll get.
