I have a 2005 Impala LS 3.8L engine with a stock alternator and a 100amp under-hood fuse. I don't know how many amps this alternator puts out. I will probably be getting a bigger fuse but I need to know what size too. I plan on getting 0 gauge power wire and a Hifonics ZRX2000.1D amp. The 15 L7's are 1,000watts RMS a piece so I will constantly be running 2,000watts at 1ohm. So if you could tell me what kind of alternator I need that will fit my car and how big of a fuse, I would greatly appreciate it. Any other advice is nice too! Thanks!
Actually they really are 2000 a piece depending on how you set the gain with a lot of watts to it. 100 amp fuse is awfully small for that system, you need to get up to 250 or 300 amps if you plan to run 1 ohm an another thing what ohm are the subs?? cause if they are 2 ohm subs then you're gonna need a amp for each sub.
if you are running 0 gauge with 100 amp fuse you are fine however save your money on the alternator and purchase a capacitor instead. if you really are getting 1000rms to each sub then you will need at least a 2 farad to keep the lights from dimming when the bass drops and only costs 100 to 200 bucks new off the Internet if you search it. on the other hand a good 300amp+ alternator will be significantly more. I would buy a capacitor and some good component speakers if I were you. I am running a full soundstream system with 1000watt soundstream amp and 2 Picasso dvc soundstream 10,s bridged to one ohm and my lights were only dimming slightly when the bass dropped in my 93 Isuzu pup minitruck and so I got a 1 farad lightning cap to put an end to that because the stock alternator is my only option as manufacturers don't offer many aftermarket parts for Isuzu like they do for Toyota, Nissan and Mazda imports. keep thumpin bro
