Both of those specs are RMS and the F540 is 700W max...not sure about max power on the M501, but it's plenty for my JL W3v2D4. It's not an insane amount of power, considering it's all in a 2003 Neon SXT, but it fits the bill. 😛

I've had my system tested and at about volume 24/35max I hit 130dB. (maxed the meter). Why do you need to go louder? 😛 Do you feel like going deaf? 😉

Exactly what speakers are you driving? I run all Boston interiors and have a single 12" JL sub. Are you trying for competition?

EDIT: I should add that my lights don't dim much until I go over volume 20. I don't listen to it loud because I appreciate great sound and also my ears, too. This is why I chose a cap instead of a more expensive alternator.

I'm not trying to go deaf, or enter competitions. I'm running Polk Momo Comp's for my front, Infinity 5x7 rear. And 2 Atomic 12" subs. I doubt I could hit anywhere close to 130, but I know at 3/4 volume my head hurts. I don't want to go the cap route, it will get rid of my dimming, but it just masks the problem. My Alternator will still be straining and it will die just as fast. I'm trying to prevent that from happening 🙂

If your not hitting 130db, your amp is nowhere near 1400W RMS. I would say, if anything at all, your amp is 1400W peak (1400W for 1ms @ 1Khz). I had 2 12" Pheonix Gold subs juiced by a Pheonix Gold XS 2300 (300W amp) and was close to 140db.

How much did the stereo cost?😕

you are prob broke,now.

LOL HAHAHAHAHAHAHAHAA

my stereo is so loud it almost stalls my car.

Keep doing this you will burn out the computer that controls the car.

A computer is $200-500.

Take the stereo and put it away,untill you can add a Larger alt.

Yeah when I was 18 I had a loud stereo in my car.
I spent 1/2 of a one week paycheck on the whole system.

My current car,I am going to add a stereo to,I bought the speakers already,
4 speakers cost about $100,and I plan to spend between $100-$150 for the head unit.

I am sure your system is louder than mine,but,I bet my car is cooler.

If that's the case and that the cap is only masking an issue, perhaps I should look at a new alternator as well? 🙁

it's only a strain when the music is loud, it gets worse with more bass. I listen to Hip-Hop, and if I turn my deck up enough when it's dark outside, people can follow the beat by watching my lights flicker with each bass hit.

I'm not a car audio, or electical expert, but nobody with real car audio knowledge I've spoke to has ever suggested caps as a good, or even decent solution. They're more of a band-aid. And if anything will make things worse, because if you don't see the effects of the strain (lights dimming etc) you'll probably not worry or think about it, and keep playing the music loud.

Good, then I have nothing to worry about. 😛 Are you one of the young fellows that vibrates all the cars next to you at a stop light? It was hilarious...one time a buddy of mine and I pulled up to a light. The car in front of us had a LOUD stereo, and I mean LOUD. Anyways, it was vibrating the bumper of the car behind us. 😛 It was a junker and I'm sure didn't take much in the first plate, but it was funny. The floor plates in my friend's car were vibrating, too.

If you are one of these people, give me your address so I can can come kick you in the junk! 😀

Is this a joke? 1/2 a week's paycheck isn't much for a complete car system unless you make 100-200,000 dollars a year.

My system is around 1400RMS, I don't turn the volume up that much though, I'm sure I could hit 130 if I did. if I turned the gain up on my amps and cranked my deck to 3/4 volume I might even be able to hit 150 🙂
