I finally did it! 1500w rms!

The guy that I worked with on my system was completely against capacitors calling them a bandaid. I see the logic behind them, but I do just fine without one and I'm pulling a total of around 1800 watts through my 5 channel amp. What made the biggest difference for me was replacing my grounds with 0 gauge wire and my positive lines got 2 gauge. Also added a second battery which is made for audio.

So Tom, John, X ect... when u added ur second battery did u isolate it from ur other battery? how did u wire it up? I actually bought 2 Optima yellow tops a while back and was going to mount one in the trunk but changed my mind because of some things i heard.
I was told that adding a second battery would also tax my alt, so i must isolate it. whats fact? and what is Fiction?

How bad is your dimming?

My second battery is on an actuator that is triggered by ignition. When the car is off, the second battery is seperated from the system to prevent it from fighting with the main battery (I have heard stories both ways about whether batteries will fight or not). Another nice thing about this is that if I run one battery dead, I put in a manual switch for the actuator to kick on the second battery and I can then start the car.

That'* crazy voltage drop. I'd definitely either not bump it that hard anymore or wire it back to 4ohms until you can get your voltage stabilized cause with your voltage dropping that low you're asking for problems far beyond frying an amp or sub. I'm gonna be honest with you, if your voltage is dropping that bad I can't imagine a 140a alt is gonna do much for you. Do you know any specs on the alt besides that? I'd be interested to know what it does at idle...I'd guess somewhere around 40-50a, you probably won't get full current out of it until about 2k rpm. How much is this alt gonna cost you? Hopefully very, very cheap as in less than $100 cause anything more than that you might as well save up for a nice 250a Mechman h/o alt or an XS Power D1400 and VCM. The battery is a 14v model and the VCM allows you to adjust the charging voltage of your battery. Mechman has a video up on YouTube that shows installation of the above setup in an older GM Truck with the stock 105a alt that'* pushing an RD Audio 1500 watt amp and two 12'*. At idle, system voltage was 16.4, at full tilt it only dropped to 16.3!
Are you really running 4ga. power wire? You really should upgrade to at least 2ga, 0ga would be best though.

i just adjusted my gain and its not as bad... hasnt gone into the red yet but i havent really cranked it yet. I am using 4 ga wire however its not ur everyday 4 ga wire. Its Knu Koncepts. Steve meade runs this wire (im sure he uses 0 gauge tho) its very high flow. Super fine strands.
The alt is a stock 140a alt.. was looking at Power Bastards alt. but they are pricy.

Oh yeah, Meade doesn't run KnoKonceptz wire, FYI, he runs Fosgate wire.
Any h/o alt is gonna be pricey. Might be a good idea to go ahead and pick up that 140a alt and then just get the 14v battery and VCM and you should be golden!
