Power problem?

[calderb123]

So Up until a week ago i was running 2 jl 10w0 with a 600 watt kenwood amp.

Then one of them blew and i got a good deal on 2 10" mtx jackhammers and once i installed them and broke them in I turned the gain on my amp to almost all the way up. As soon as i did this when music was playing my volt meter would flutter from around 14.8 to 13.5. So i got a second battery today and thought the problem would be fixed. The volt meter is now reading steady around 14.5 but every once and while the subs still cut out. I got to thinking maybe it was my amp overheating? or even worse maybe a bad alternator. Any help or input from you guys would be greatly appreciated.

Thanks!

I'm thinking you need more powerful subs. if your amp is 600w rms, and the jackhammers are like 100, you're over powering them. Get some w1s. Also, adjust your gain. That's the first thing.

theyre around 200 watts rms each. and the amp is 600 watts peak power. my 10w0 were 125 watts rms and never cut out. so thats why im curious

I would start with adjusting your gain properly

how do i do that?

Don't turn it all the way up, it's not a volume knob.

how do i do that?

I could right off when you said turned gain all the way up.....this is where it's worth to have a dealer properly set gains, before you blow up your new gear....

whats the impedance of the subs?
