220 watts RMS x 1 at 4 ohms (400 watts RMS x 1 at 2 ohms)
the amplifier may be over-driven. are there red protection lights coming on the front panel? Or a loose wire - power, ground, or speaker.

My amp won't play bass everything is hooked up


I have a similar problem with my 2012 civic, I hooked up my 1800w kenwood mp to my 2 12" w6s and 1 song plays and sounds great, the rest of my songs have no bass from the subs, just the car speakers sound normal so I dont know what the hell thats all about. I thought it was a wiring issue but I can play the one song all day and it sounds perfect so any suggestions? thanks in advance

Speakers cut off when bass goes up


probably the amp going to safe or protect mode judging by the fact that you have 3 subs wired to it i would say it is not 1 ohm stable try disconnecting 1 sub and see if it still happens this will be running a 2 ohm load rather than 1 if it stops happening then you need to figure out a better wiring configuration that will work with your amp.

I have an alpine head unit and a kenwood 1000 watt amp. I have two 12" subwoofers hooked up to the amp and thats it. I got my tweeters, and door speakers powered by my head unit. The bass was cutting in...


your amp may have burned out or try checking the fuse in the amp and the car also your channels may be burned or you may jus have water damage to the amp

Sony amp 1000w


Check the wiring of the speakers (both inside the box and between the box and the amp). It sounds like one speaker is wired incorrectly at one connection point.

I bought a 500/1 jl audio amp and also a w7 10 sub


if its cutting off and right back on then check your ground and your power wire makes sure both are connected good and none of your fuse's are blown, either that or you got a wire hooked up backwards in the sub.. but my guess is that the sub is hooked up wrong... that sub should be hooked up in a series or in parallel,

ok if your running just one speaker, it should be hooked up like this and 2 speakers are a different way...

this is parallel :pos to pos , neg to neg, then one wire coming from pos on sub to pos on amp then neg on sub to neg on amp but bridge the amp on your amp should be 2 pos and 2 neg in two different channels take the pos off the sub into the pos on 1 channel and then the neg from sub to the neg on the other channel,

this is series : on the sub it will go pos to neg then the other neg and pos will go to the amp, but make sure the pos and neg r on different sides of the sub, dont hook them both to the same coil

if your need more help give me your email and ill send you a pic of how to do it...

AMP FOR SUB SHUTS OFF SOMETIMES


your amp may be overheating, or you have it up too loud and the surge protector is shutting it of in fear of damage to your amp.

Hooking up a new 8" woofer speaker to my amplifier


If I'm reading the amp manual right, you should be able to connect the amp in 3 channel mode. To do this:
  • Connect both left door speakers in parallel to Ch A Left.
  • Connect both right door speakers in parallel to Ch A Right.
  • Bridge Ch B and connect it to the new 8" sub.
  • Set the Ch A LPF/HPF to HPF.
  • Set the Ch B LPF/HPF to LPF.
This should allow you to run all 4 door speakers and the sub from the amp. It will also automatically route non-bass to the door speakers and "only bass" to the sub.

More bass


Run one set of RCA lines from head unit to amps if you only have one set of pre-outs on the head unit, then at the amps, use an electronic crossover to split between the two amps, and this will also allow you to control what frequencies go to which amps/speakers. You should use one amp for the speakers and the higher power amp for the subwoofer. You should not try to connect both to the subwoofer. Use 4gauge cables if possible. If you have more questions, just ask.

J/l 500/1 amp


I'd lay you odds that you are driving the wrong speaker impedence and that you may have damaged the amp. This is most often true when you improperly bridge into the wrong load. If you are lucky enough to not have damaged the unit then you need to get your speaker load right at once before you fry it, if you do indeed have the wrong speaker load (too much).
