Im planning on buying 2 15,4 hccas i want to know what i need to have it running good and not killing my battery plus will it even fit in an 02 impala i just need to know everything really what amp what box what wires everything any help is appreciated thank youuuuu
Well you should know if it will fit or not. Measure the trunk area and see how big it is, if you don't have about 32 inches across then they may not fit. Do you have a budget for the amp and wiring that you would like to stay around? For the box, your best bet is a custom box if you have the tools to make one.
if im not mistaken..those hccas take 2000 rms each?? so you'd be running at least 4 rms, thats not including the mids/high to keep up with two 15s of that nature. you would need to upgrade your starting batt and add a big batt in the back, do the big 3, get a good size (200+) HO alternator, and at least one run of 0 gauge. amp pushing 4k rms is going to cost you a good grip too. i would say no less than 1500 what you want.
These subs will not only take up about 32 inches wide but they will also be very deep. If I remember they are about 12 or 13 inches deep which should require about 4 to 4.5 cubes maybe more. It will take up most of your trunk. think about getting your spare tire out, grocery shopping. I learned this lesson the hard way. But if you have the room and dont mind giving it up, take a look at the Crossfire VRA 4000D amp, 4000 watts at 1 ohm @ 12.5 volts, fan cooled. Should push those subs with no problem. Upgrade the wire from the alt to the fuse block, fuse block to the battery, upgrade the negative battery to chassis, upgrade the engine to chassis, all these should be 4 awg wire. If you do those things and your lights dim then ugrade your alternator to at least 200 amps.
you dont have to give the subs their full rms power you know. it would be nice, but if your electrical cant take it then maybe 2k will do just fine. thats still going to be pushing it tho. the BIG 3 is deff in order. i know a kid with a 3000 watt amp in a mini on stock electrical and it plays at low volumes fine, but crank it up and his car wants to die due to super low voltage.
