    I know its a dumb question but if i hooked my 8 gauge + to a marine deep cycle battery in the rear of my truck an grounded battery and ran leads off the that battery to my amp would i gain from that?

    A lot of others can give you much more advice than me and i'm sure some will chime in, but in general i believe that in car stereo we tend to stay away from deep cycle batteries.

    Also others can explain better than me as to why, sorry I can't help more.

    i used a deep cycle marine battery for a while right next to the amp, never had a problem with doing it, never had any troubles. it helped my voltage. i also mixed batteries and never had a problem either. HOWEVER im not telling you to mix batteries just giving you my exp with doing it and using a Deep cycle marine battery,

    as far as deep cycle batteries go, AGM batteries are deep cycle batteries... .... for example my current Deka Unigy AGM's are deep cycle batteries....

    Aha, that is right. I know others can explain the deep cycle thing more.

    Surprised nobody said to upgrade the wiring first... you said you're running 8 gauge? What kind of amp/s are you running off that? and why the need for a 2nd battery?

    Also, you could use both deep cycles like that, but be careful the battery has enough cranking amps/cca to start your car.

    True, Big 3 is the 1st thing to do, and possible ho alt. that will solve it for good.

    If I were you, I'd save myself a future headache and just get a ho alt... maybe they make a different alt for a similar model car as yours with higher output? With 1k rms, you shouldn't really need an extra battery, depending on your alt, and wires.
