As far as the positive terminal is concerned yes, but, you had better put in a fuse in line. for the negative terminal it is much better to wire it to a bolt or screw that is bolted through the chassis. this will keep your equipment better protected from surges, or any other unforeseen voltage irregularities.
you can hook a car radio directly to a car battery or even a car battery charger with out problems, I have done it myself, the only thing to remember is that it needs to have 12 volts and the polarity (+ -) needs to be correct.
Yes you can, The battery is in the back of the trunk, you hook your amp up to the battery and then the amp to the sub, you need to buy a converter for the back speaker, you can buy one from any car audio shop, you then splice the wires in the back and hook up your converter, then hook the converter to the amp, But get it professionally installed because my buddy tried to do it with his magnum and it started to blow fuses, It shocked him today, he is going to get it professionally done today
RED wire goes on +, and the black wire gets wired to the body of the car. Which is ground -
buy a wire kit with thick enough wires for the amp.. It should have the instructions but heres the basics.. thick wire goes to battery from amp and you need to drill a hole through firewall (usually under carpet buy you gas and break pedals) to run it and it should have a inline fuse.. RCA wires go from amp back of radio a wire from amp ground need to be connected to a large metal part of your car. memory wire needs to hook to a power source that's only on when your cars on that way your amp does not kill your car battery when you park. and then connect all the speakers.
No, you can charge the battery while it's in the car.
Usually a car battery, but it also depends on the size of the battery.
Jump the car from another car battery or hook a charger to the battery.
Hook positive up first, negative last.
It will be a 12 volt battery.
In 24 hours it will be charged enough to start the car. You really need a much larger charger for a car battery.
well you hook it up
Do you mean the main power from the battery or the remote turn on? If you mean the battery power, usually amp add on kits come with distributor blocks. You make one run of power wire from the battery to somewhere close to your amps. Then, hook that wire to the block, and run a new piece of wire from the block to each amp. If you mean the turn on lead, just make one run from the head unit to the first amp, and then run another piece from the first amp to the second.
