More Than One Audio Problem

I recently installed different audio components in my truck. I have a ZR240 Kicker amp feeding two 12" JL w1 audio subs. I can hear a strange noise in the subs while the music is playing, can somebody tell me what may be causing this strange noise?

Also, my pioneer 12 cd changer turns off all of a sudden, and sometimes my pioneer DEH 6500 won't catch the changer. Could this be a bad wire connection, or a bad cd changer cable to the head unit?

Something else, I like to hear the music while washing my truck. The battery goes dead after only a few minutes of playing the stereo (10 or 15 min). I have the kicker amp mentioned above and also a small rockford fostgate 100 amp hooked up to a pair of 250w pionner 6x9's. Is this too much for the battery? What kind of upgrade can I do to avoid this problem?

One last thing, I thinking about adding two separate small eclipse tweeters to the truck audio system, would this help my set up?

What kind of strange noises do you hear? Is there some sort of vocal coming though?

The cause of the cd change can bet bad connection or wire. Check both out. Most likely, it's the wires that are the problems.

When your car is off, while music is playing, you're going to drain the battery quickly. With the amps drawing a lot of current, your battery wouldn't last long. It's bad to play a long time with the car off because the battery isn't being recharged. The battery is actually gets damaged when the voltage drops down a lot. You can never get back to it's full potential. It's called non-reversal chemical reaction. You simply can't get it back to it's original state. You may be close to it, but never will it be like new again. To play longer, you can add second or multiple batteries to the car, but then you'll want a bigger alternator (or an alt. rewind) to charge the batteries. My suggestion would to be just let the car idle and play your system.

If not, then get a battery charger that will have sufficient ampere to supply to the amplifiers. They will cost up to around $100 for a good one. Not only that, but you can set the recharging rate to about 2A to trickle charge the battery. That way you can recharge the battery without having to turn on the car. Leave it in around 50A or so when you're washing your car. lol.

You can also buy a device that will shut the amps of when the battery voltage gets low..its about 20 bucks at most stereo stores.

you can get a optima battery, they are indistructable IMO. I garaged my car for 3 months with the lights on and killed the battery, hooked it up to a quick charger and it was up and running like new (actually cranked the car quicker). tna-sports has some of the best prices...yellow top for stereo

lmao ..... I have a red and tellow top optima battery in garage. They are both dead as a doornail - and they will NOT recharge

yea. they (yellow) aren't true deep cycle batteries, unfortunately. Only deep cycles i know are big, heavy, expensive. but boy do they work... :D
