    i have 2000 f150 i used to have kenwood 900watt and then 1800. my speakers were alphasonik 1000watts. had just one speaker had it hooked up right power and ohms not nearly even cranking it they would blow they were in an obcon box which are bad for speakers alone but very loud. got the 1800 kac-9152d still blew speakers quietly? now have massive p1000.1 2000watt hooked up to alpine 1500watt swr-1022d blew upish didnt spell didnt grind voice ciol just stopped is al this happening because i dont have an extra batt or power cell. i had a kenwood deck now pioneer with optima batt and high out put altenator . is it just an un consistant power or just crap speakers bla bla bla.

    Welcome to CAT!!!

    Well alphasonik isn't a good brand to begin with. it sounds to me that the reason you keep on blowing your subs is because you are clipping the signal. Meaning your pushing your subs too hard.

    What gauge wires are you using for your system? do you set your gains with a DMM? you said that you hooked everything up right, what are the exact models of your subs that you blew? SVC or DVC? how many ohms?

    In my system, I'm using a stock alternator and a stock battery and I have no issues except for a little dimming but once I do the big 3 that should stop it from happening. I'm at about 1700 to 1800 watts rms so I don't think that is your problem.

    i have a few questions.

    1. what is the gain set at?
    2. are you using any bass boost?
    3. are you using an eq?if so do you have the bass cranked on it?

    like CC said. i too am running a stock alt and 1 batt in the stock location.(optima red top) and i have a total rms of 1100 watts. big 3 and no dimming tho. so you dont seem to have a power issue.

    just double check the speakers impedance just to make sure.

    If you keep blowing speakers it is user error...seems like you need to learn how to correctly set up the amp and deck

    good thought, you may be going lower than what the box is designed for and at that point with that much wattage its all bad

    also make sure you're starting out with the gain at the amp on 0 then slowly work your way up, dont go above half for now and see what happens.
