A capacitor will solve your problem with your headlights dimming. Basically its the same as the battery but is designed to release charge much faster, and is perfect for huge drains of power like when bass drains power.

Make sure that your earth connections are big enough also. Often if the earth for the amp isnt large enough and isnt grounded properly you with cause an unnecessary drain on your battery. Unless you're pulling in excess of 800w RMS then your headlights shouldnt dim unless your current battery is shit, or your wiring isnt up to scratch. Replace your current battery with a deep cycle unit - Odyssey or the like. Use 8 gauge earth wiring on your amps for anything under 800wrms... 4 gauge for anything above that...

Installing a 2nd battery should be your last resort, and you would want to upgrade your alternator to go with it or you're wasting your time really. For cheaper you could make your current system run properly.. Your car uses bugger all driving along anyway, so if you're worried about being able to sit there for a while and play PS3, you're not going to get much benefit from having a SECOND battery... beause the first battery will be almost fully charged when you stop anyway..

Seeing as you already got some cable from work, make up some cable to go from your battery to the chassis. Something like this.

That is 2 x 35mm2 cables. Very much over kill for what I have, but it does the trick :P

      just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.

      My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.

      To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
