A 4 ch amp is an external aftermarket amplifier that runs off of a usually hefty guage power wire(w/inline fuse), a 12v remote turn on, and a ground(same gauge as power wire). These amps will power up to 4 speakers(@4ohms)and are generally more powerfull and have more clarity/quality than a factory system.They will have a high pass filter(HPF) that allows you to eliminates low frequency tones through the door speakers allowing them to play louder and not blow due to too much bass(low frequency). All cd players have a built-in amp and that is where you see the deck specs saying things like 45wx4, or 52wx4 or whatever. BTW, these are generally all max power ratings, in reality it is more like 20w or 25w per channel rms/continous power. Regardless, run off deck power unless you wanna blow a wad o cash on more car audio goodies. At my work we offer many amps of all kinds, brands, and power ratings. You shouldnt really have to spend more than $200-400 for the amp itself depending on quality and power. Then you will need a 4g power wire ran from battery to distribution block where it turns from 4 to 8guage and from there goes to the 4ch amp and monoblock or 2ch sub amp, as well as a smaller(18g)wire coming off your aftermarket cd player(blue w/white strip) to tell the amp when to turn on. You will need same thing (4g wire) for the ground but just less length because it doesnt need to run the length of the vehicle. Now youve got your amp powered on, now for the audio signal. You can buy rca's from anywhere to $10.00 to $100.00 or more. Depending on who you talk to, you will get varied responses. Some say it makes a world of differenc having super high quality(expensive) rca's, then ya got guys like me who just cant hear enough difference to justify spending hundreds on rca's. Form your own opinion after comparing apples to apples. Also, your preout voltage on the deck will come into play, as some more expensive decks(cd player) have a higher voltage preout resulting in a stronger/more clear audio signal. All that being said, possiblilities are endless and your spending can be to. I would say if you were to buy everything and install yourself, you would be looking at about $350-$600 just to add a 4ch amp. $250=kicker DX400.4, $150 for complete wiring from Scosche(cheap sh*t), $40=distribution blocks(also Scosche). P.S. Dont cheap out. Pretty much dont buy unless its name brand(ie.-kicker, alpine, kenwood, polk, memphis, jl audio) and for god sakes, STAY AWAY from Dual. Also, if you buy good amps and speaker, then buy crap wiring, its not gonna perform the same. Id recommend cheaper power, ground and remote wiring, paired with a medium range audio cables and good deck, and higher quality amp and speakers. Also, 0-250true rms watts/power=10guage wiring. 250-500watts=8g, and 500watts or better generally requires 4guage power and ground. Under powering spkrs, especially subs, will make them fail quicker as they rely on the power to move them in and out which is what helps cool the voice coil. You can put a 1000w amp on a 150w sub if you turn everything way down and be fine, but you cant put a 150w amp on a 1000w sub.
