What is the difference between two way and one way security systems in car alarms?

My car speakers and subwoofer are making alot of noise?

• Ok. So one morning I start my car and once the radio clicked on my subs started pulsing hard and then my damn sub amp blew. .SMOKED. I disconnected the amp and began to check everything. All the ground wires are in tact and are grounded correctly. Bear metal, no paint. The RCA's are connected right. I connected one of my older amps and then turned my car on. The door speakers started whinning and subs keep pulsing. Whenever I rev my engine, the noise get higher in pitch. When I use my turn signal, the speakers make a clicking noise also on top of the whining noise. I went and baught two groud loop isolators from Radio Shack. One set for the rear and one for the front. I turn the radio back on, the whinning stopped for the most part, but now the music comes out half-way and distorted. Sounds like as if when you don't plug in your headphones all the way or speakers into a cd player or computer. I made sure the RCA's were in snugg. I even tried connecting only one Isolator at a time and the noise was still there. I'm already blowed that my amp blew but its still under warranty so no worries on that. But I still can't find the problem. What I don't understand is, I've had my system for 3yrs now and never had this problem. I have 6 12" Kicker CVRs running on a 15001 Orion mono amp. My door speakers are cobalts and is being ran by a cobalt 600. My headunit is a Pioneer. I've got a Batt-Cap aka tiny battery i guess powering the amps. I DON't KNOW WHAT TO DO!!!!! Any suggestions people?? I'm going out of my mind trying to figure out the problem. The isolators aren't helping correctly. Like i said before, this never happened before. The only thing I changed recently was I built a custom vented box. The box made a huge difference in sound and I had to lower the gain. This was of course before the amp blew. PLEASE HELP ME!!!! PLEASE!!!!!!

• Answer:

  If the subs and speakers aren't working correctly and you replaced the amp, try replacing the head unit. Or because you blew the amp, it may have damaged the subs and speakers.
