How can I wire my boombox?

I need help wiring a car head unit for a boombox I am making. The problem that I'm having is that to save my settings, the head unit needs a constant 12v supply. Currently, I have a computer power supply going to the head unit supplying the 12v along with 5v for a PC fan I am using to help with cooling. The problem is that I am planning on putting in a motorcycle battery and switching between the power supply (wall power) and the battery (portable). I need all components to run off of either power source and to be able to switch between them without overloading the system or losing the constant 12v. Please help and sorry if that didn't make sense or was too complicated.

MP3 player to car headunit built in amp

How can I connect my mp3 player to the built in amp on my cars head unit.  I suppose i need to do some soldering but I dont know what I am looking for.  If I connect the MP3 player to the speaker outputs it plays too softly.  I need to get it going through the amp in order to play loud enough. How Can I do this?

Car stereo puts out much less power than speakers need?

I'm fairly new to car audio. I just put in a Pioneer MVH-370BT headunit into my car, and while it is working great right now, it is evident that I'm going to need new speakers soon because the factory ones are not very good. I was looking at either the Kicker 40CS54 2-way speakers or the Kicker 41DSC54 2-way speakers because many people have recommended these speakers. The problem is on the website, the pioneer headunit only says it puts out 14 watts RMS power while the speakers say that they use up to 75 watt RMS. I'm trying to avoid getting an amp because I'm going to be putting the speakers in myself and i don't want to have to drill a hole through the firewall. So, my question is what will happen if I run the speakers with the 14 watt RMS receiver? Will it just not play very loud? Will the sound be very distorted if I try to play it loud? Is this bad for the speakers? Thanks!

Should I put sound deadening/dampening material in my car?

I've just spend a little over a grand and blown the majority of my budget on new speakers amp wiring and a headunit for my car. I haven't bought any subwoofers. I'm happy to go over this budget if sound deadening will make a large difference. Anyway, I was just wondering- road noise and all of that aside, will sound deadening make my stereo sound noticeably better? As in, sound quality alone Should point out that the speakers are 300 watts rms all up. 6.5" "woofer" 4" midrange and a tweeter that's under an inch each side. Thanks heaps!

What battery should I use to power a DIY boombox using car audio components? Answered

I've been looking at car stereo boomboxes (DIY of course) and had a simple question on how to power the stereo: WHAT BATTERY SHOULD I USE? I plan on running a Kicker ZX300.1 mono amplifer to power three 4ohm SVC subwoofers (wired down to 1.53 ohms), and a wallmart headunit that I suspect draws around 10amps of power connected to Kicker DS60's. I'm also fairly certain that the amplifier draws 30 amps of power (300 watts / 10 = 30amps). If this is correct does that mean I need to have a battery / set of batteries rated at 40 Ah? (I know I need a minimum 12v to run car audio equipment, the question is based on the Amps Per Hour rating of the battery). I Guess what I am asking is does the power source need to be rated at the "x" Amps/Hour where "x" = the total amp draw of the system? Thanks!
