    Y'all removed TR32, aren't y'all?

    Probably running one of those leenyers, too...

    Awww, Andy!

    Nip it in the bud.

    You're either running 100w+ power, or the RF interference when you key down is confusing the vehicle's computer, y'all.

You don't say how much power you  are running, but it must be quite a bit, or you have an amp you're not telling us about.  By keying up the radio, you're putting enough load on your electrical system to pull the voltage down which causes you lights to dim, rpms to drop, etc.  When you key off, everything goes back to "normal" which means no load so the engine will surge momentarily before it recovers.  Depending on how many watts you are running, you may also be affecting the alternator regulator.  Your alternator may also be a little weak.

Ignition key lights up but does not turn over

It's common for the battery to have enough voltage to make just about everything electrical on the car work, but not have enough power to crank the engine. I would check your battery first. When you try to start it, does the voltage drop below 12 volts? If so, you need a fresh battery. If you don't have access to a voltage meeter and your battery is more than 5 years old you can assume that you need to replace it.

Replaced starter, car started for 4 days. Fifth day car wouldn't start, just made a clicking noise. What could it be now?

If the lights are dim it is a battery problem. It might be a just dirty terminal or the connection on the starter is not good. Check the voltage of the battery with the lights on, should be 12 volts. If it drops when you try to start then it is faulty. The voltage when running should be 14 volts or more.

this seems like its a problem with your alternator, it might not be charging correctly, check the voltage with a volt meeter on the battery terminals, if the voltage is lower that 13 or 14 volts, you might need a alternator rebuild!

Hi Joey,
It sounds to me that the power supply you are using may be a little under powered. It's not really a bad problem as long as the voltage doesn't drop below about 10.5 - 11 volts. As for the Galaxy. I'm not real certain of the question but a Galaxy will usally use more current to make it work properly, so I would suggest a bigger ( more amps ) power supply.
Good Luck and I hope this has helped some
