Clipping (or sounds of farting through sub box in certain songs, or tones) is occurring, and even after having a alpine mrp 1000 amp, a jl w3v3 dual subs from a very well know distributor of high end audio, and a alpine 9886 head unit, all are under one month. old. Previously had a dual jl w1 and 500 watt system. I have called the dealer of the jl box, and the amplifier distributor, and each plot me against the other blaming issues. I need an intelligent person, or technician that can be honest about how to do something. I am alot older than most that would listen, much less own high end audio, but shortly after getting the alpine 1000 amp, I noticed that clipping occurs and sounds very damaging, but the OHM load is still between 1.8 and 2.0 on subs. I have four gage wires installed on the system. But, I have not done the big three upgrade, and I know a CAP will not make a difference. my alternator is ONLY putting out 80 amps (wimpy) and there is no aftermarket alternator that will work on a 1999 Nissan sentra, 1.6, gxe. I need to know when using a bass mekanik CD, playing one or two songs, the why and how to solve the clipping on brand new gear. One says amp is starving, the other says subs are blown, and have been tested to show they are not (even though I can't see the former, or spider) blown. Is there a remedy, to deliver to dealer of sub box with two jl's, which will have them think that I have a legitimate gripe? or does anyone here have, or had a relative problem such as this? Anyone with any input is highly encouraged. Thank you for your valuable time reading this lengthily message post.
