    Just like the title says, I plan to install a Alpine headunit power pack. I also have a 12 inch kicker sub. I have not purchased an amp for it yet. ... Crutch field says higher power systems can damage sensetive electronics. What are they referring to exactly? My sub can take 500 rms. My power pack is 45 rms * 4 . Should I just get a lower power amp for sub? Will it just fry my 12 volt battery if I go big? Or will it damage the inverter which costs more?

    600 watts RMS is about 840 peak. With efficiency losses, that is pushing the 12v system pretty hard. There is a 100 amp fuse in there (I think it is 100).

    I'm currently running 8,000 watts on 4 subwoofers with 3 12v batteries, my goal is too reach around a total of 10,000... so if I can run that no problem u most definitely shouldnt have to worry 20150625_234214_zpshm9glnk2.jpg 20150625_233614_zpsfbhofjmt.jpg received_4850272111063_zpswtxncuc7.jpeg

    The 3 batteries are paralleled with the car 12v battery? As a load, 8kw is around 850 amps taking into account the losses. Can you give us some details on the wiring?

    Yes the batteries are wired in parallel. with a volt meter to monitor the voltage
    • the stock battery was replaced with a agm Xs Power D5100 60AH max amps - 3100,
    • 2nd battery is agm Xs Power D2400 70AH M.A.- 3500.
    • the last is a brand new lithium Limitless 22AH . (2 months old)
    I've been running my system for about a year and a half with just the 2 Xs Power battery. wires are all OFC 0 gauge 2 runs from the from the inverter to the batteies 4 Crescendo Bc2000D each amp is 2k rms. and from time to time i put my car on a home charger depending on how hard ive been playing but the car stock charging system still able to charge the batteries fine.
    I'm just waiting on learning how to make a custom door panels so i can upgrade the mids and highs...

    people ask me why i tell them why not.
    this is not my first hybrid system. I've had a 2002 prius with only 4k at that time. which was literally ripping the car apart..

    I have found that serious hobbies make us just a little crazy. An impressive set-up.

    Was told as long as you do not pull more then 150 amps, which is what the inverter is rated at, you should be ok. I been running a JL Audio HD900/5 for going on seven years now, and never had any issues.

    The little 12v battery will not last long trying to run a system. Just run your system with the car in "ready" mode, then the inverter takes care of everything.

    I need guidance please.

    Finally finished my 1st car audio install and loved hear wife complain that I was rattling dishes inside our house. That little amp and 2 Subs surpassed all of my expectations and beyond. I drove around for about 30 minutes with base slamming wow grinning from ear-to-ear and then subs quit.

    I pulled into O'Reilly Auto Parts parking lot that was 1/4 mile nearby put my hand on the amp expecting it to be overheated and it was not even warm. The blue Power indicator light was off.

    I then checked the 60w power fuse from amp kit mounted near battery and it was perfectly fine.
    I then checked interior and exterior fuses. Did not find any fuses blown there either but there are a lot of fuses and I did not pull every single fuse.

    Got back in the car pressed start button and got key lock code transmission warning seed dealership flashing Triangle exclamation with check engine light.
    O'Reilly's salesman came out and performed a battery diagnostic. 325 cold cranking amps on OEM battery tested good but read "needed to be charged up."

    By the way O'Reilly's refused to use their jump pack to help me out because they consider jumping off hybrid vehicles to be a liability.

    After maybe 45 minutes to an hour of not being able to start Prius finally starts back up. P lock code goes away but while driving home messages say bring vehicle to dealership still maintain check engine light exclamation in yellow triangle.

    Car is running fine now but amp light does not turn on and I do not want to damage my vehicle.

    A few guys have suggested that I install a separate secondary battery to help power the 600 watts being pulled from Amp.

    I'm reading so much conflicting advice that I'm close to throwing in the towel and putting in a pro shop but hate to give up being so close to a complete install done on my own.

    Any advice or links are very much appreciated.

    I haven't had any trouble with my setup. My subs are rated for 400 rms. I have a 500 rms amp. I upgraded my front with some Alpine 6.5 components. And an Alpine power pack.

    I did the JL 900-5 amp also powering a JL 10w6 and Focals in all the doors with an Auddision controlling a lot of it. Very happy with it for what it is.
