1000 watt rms

Another note: Most people think the bigger the better, but realistically its wasting your money. Theoretically, if say you only have 40 amps left over, once again the math tells you 14.4volts x 40amps = 576 watts. 576 watts is the absolute maximum you can get out of any amplifier regardless of the brand. Lot's of guys go buy 1000's of watts and don't realize they're only getting 1/3 of what they paid for due to the weak electrical system they're implementing it in. If it were me, I'd either fork over the money for the upgrades, or downgrade the amp to 500/1.

the car comes with a 130 amp alternator. if you do 14.4 amps x 70 amps that=1008 watts. try to keep in mind that i am not a huge fanatic about subs although i really like them. unlike you guys i wont be able to tell all these little voltages drops and so on. i will rarely pound all out mostly 3/4 and if i do full volume i wont even do it for a song. dont want to wreak the car

HID lights are more efficient than halogen:laugh:

you'll be fine. I dont see why your all worried over installing an amp. worse that can happen is it dims you lights, UH OH, just turn it down or upgrade. simple as that. I am runnung a sundown sax100.4, sundown sae1000d and audiocontrol dqx(maybe .5amp draw) i dont dim or get voltage drop at idle. I am only pulling about 400watts from the 1000d and IDk how much for the sax. i have a 90amp alternator. i as actually expecting a nice voltage drop, but i didnt get it. You will probably be happy to find that your lights wont dim, can hid's dim?

so your saying everyone always runs there electrical to the max to only get that many watts? you have lots of math invlolved there, why did't you calculate wire size, heat(resistance), wire length, any resistance in connectors then calculate. apply it to real life please.

oh and yes, downgrade your 1000/1 to another jl becuase they are the best.

you want me to downgrade because 1000/1 are the best

Well it's simple ohms law. But I would ask, what sense would it make to go buy the best 50" 1080p Plasma if you were hooking up a VCR to it? The results are the same, and the system is only as strong as the weakest component. It's like a high output turbo charger with a stock fuel system. What's the point? In most cases, people waste tons of money buying amps that the charging system cannot sustain, trust me, I've been reluctantly installing these systems for over 8 years. But my checks are paid by folks ignorance, so I guess I can't complain. My advise is to drop down to a smaller amp- because the results will be the same regardless.

First trick is to re-ground the battery with the same gauge wire you ran to the amp. Usually dimming lights is a difference of potential problem, say you run 4awg back and are still using the factory 8awg return to the battery. Easily overlooked in the circuit. Also, if you do the math 1000wRMS/14.4 volts = 69.4amps. Depending on the car, most cars use a 70% load with lights on/heater on. Say if you had a stock 100amp alt. you only have 40amps left to play with. Not enough for sure, and theoretically it only gets worse when your voltage drops below 14.4 (volts to amps trade off). Unfortunately the 1000/1 is a monster and energy hog and to do it correctly the whole charging system needs an upgrade, starting with the alt, the the battery, and maybe a capacitor to stabilize the voltage. Good luck!

So, just to get this straight, you're recommending a h/o alt, a battery upgrade and a capacitor.....for a JL 1000/1?

Hmmmm...

By the way - if your alternator is still stock OEM, it's a 65amp. I looked it up.

really? where did you find that info? i have the 2010 camaro ss ls3. some one said it was 130 amp constant and 150 max i believe

i was looking at the 1000/1v2 manual to see where i need to set the gain. it says to adjust it using a voltmeter. i need to set it at 54.7 volts since my sub is 3 ohms. turning the gain up more wil just cause it to clip correct? why dont they only want the volume at 3/4 when you do this? when you turn it up that extra 1/4 wont it start to clip?
