Is it the car vibrating or the sub making the noise ? if its the sub making the noise check all the screws holding in the sub and make sure they are tight or make sure nothing got sucked into your box if it is the car making the noise try using dyna mat to help stop the noise also check the surround on the sub and make sure there is no seperation of the surround from the cone

What is this amp for is it for highs ad bass


To me, and it looks like a four channel amplifier. I would say it's used for speakers. Not sub-woofers. But you can use it for subs if that is what you want to do with it.

Subwoofer Dual voicecoil wiring


1 ohm will draw too much current.those are designed for a 2 channel 2 ohm drive for each sub.running 4 ohms will be easier on the amplifier and since impedance is not constant it may run 3 ohms at some frequencies anyway. another solution if your power amp is bridgeable....put the coils in series on each woofer making 4 ohms.then parallel the two 4 ohms to make 2 ohms and run the amp in bridge mode at 2 ohms.since bass is omnidirectional,you can do it

Unwanted bass coming out of my subs


there has to be sumthn hooked up wrong bc i have had same problem with my 12' subs but it was simply a matter of my rca jacks but sense you have checked them try rewiring the speakers if that does not work then your rca module may be burned out within the amp..iso then check the amp by taking the cover off and making sure nuthn is burned on the inside.or if any wires are loose or touching.

alot of times its not just the amp that gives you better sounding bass.. A lot has a to do with a few other factors as well.. first off your subwoofer.. the bigger the subwoofer the deeper the bass. Some woofers exturde, or flex differently depending on the quality and structure of the woofer.. 2nd is gonna be the sub box. different size boxes will give your sub diff. depths of bass. ... general idea is the bigger the box deeper the bass. But if your woofer is not supplied enough power a big box is useless.   With that size amp your best bet is too run a single woofer. Probably a 10inch woofer would sound the best.. but it in.75cub inch. sealed box.. should sound great.

I plugged int he rca's but he the lowest sounding bass possibe


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.

Car amp's stopped working. Putting out a heart beat sound through subs but no bass.


could be low current ,disconnect all power including ground for 20min N.B most amps will seem to be shorted at output but this is normal due to damping ratio.
