bass cuts in and out at higher volumes

did you solder the conectors on the new wire?  If you have a volt meter, you need to use it and check the voltage at the amplifier, with the amp turned up to the point in which it is cutting off.  Black lead on the ground terminal of the amp.  Red lead on the power terminal of the amp.   How low is the voltage dropping?

Yes, I did apply solder to the connectors on the new wire. Not enought to fill up the entire connector however. (Should i add more?) As for the voltage drop i will look into it and get back to you with the results.

If the voltage is dropping, I would suspect the lack of solder before I suspect the wire.

Besides low voltage the other likely causes for the symptom you describe is low speaker impedance (which includes the tinsel leads shorting to the frame or a defective voice coil) or amp gain set too high.Support the12volt.com

Greetings, I am also having a somewhat similar experience as ncreaper247. I am running an Alpine CDE103-BT with the preamp outputs going into a Kenwood KAC-6104D amplifier, which is used to power a Polk db1040 DVC 10-inch subwoofer. I had installed it on Saturday and on my drive in to work, the music began to "skip" (that's how I can best describe it). It didn't matter what source was being used (Tuner, CD, iPod), it happened with all of them. I noticed it happened at the the middle range of the volume settings (Head Unit volume goes from 0-35, problem appears around the 15-24 mark). I looked at the amp while this was happening and it was not going in and out of protect mode (as observed by the power light on the amp not flickering - Not very scientific on my part, but I'm no rocket scientist!!). I also have the speaker wire (12 ga) attached to the amp using the screw with the square washer pressing down on bare wire. The amp is wired in parallel, so that I can draw a 2-Ohm load from the amp (which is stable down to 2-Ohms). The sub is rated for 50-270 watts RMS, the amp is supposed to supply 300 watts RMS with a 2-Ohm load. The one thing that also happens is that all the speakers do the "skip" as well, not just the sub. I will be checking the voltage when I get home, but outside of that, any other ideas? Could a problem with the amp affect the rest of the system in such a manner? Suggestions and comments would be greatly appreciated. Thanks.
