I Installed some alpine speakers with tweets and an alpine amp early last year and the system sounded great but not for long. One day I noticed that the speakers would cut out when the bass hits, though they work fine at low volume when bass is minimal. I parked the car for the night and found it next morning working great again. Then after a few minutes of listening to my ipod the same thing happened, speakers started cutting out everytime the bass was introduced past a certain volume.

I checked the fuses on the amp and on the HU, triple checked the RCAs. The only thing I can think of is that something went wrong with the crossovers. However, I know nothing about these things and need help. Any info and educational links are greatly appreciated

 

Also I'd like to put in speakers behind the seats to take care of low frequencies and leave the mid-high frequencies to the front speakers and tweeters. How would I go about that???

 

Are they cutting out and coming back on, or do they cut out and stay off? Maybe double check your ground for your amp. Also, try running the component speakers strictly off the HU instead of the amplifier, in order to eliminate the speaker/tweeter/crossover as the culprit.

 

They cut in and out. Sounds like a scratched up CD on an old CD Player
