    never... CCA is crap, will always be crap. Aluminum has the conductance of 60% of copper. We are asking to send current right? which would you rather have? 100% or 60%?

    and here goes the CCA vs OFC debate again

    there's nothing wrong with CCA, it just needs to thicker in gauge than your typical OFC cable.



    All day I'm clippin'
    voltage be dippin'
    I don't give a damn,
    cause my trunk always hittin'!

    creating a proper sound wave. Step one, turn it up until clipping. Step two, done.

    Except for the fact that my T2500 needs a 0 Gauge input and I've already split the circuit to a seperate 2 channel amp as well? Looks like I may have to invest in some OFC and maybe a small battery in the back to allow for power/ground runs.

    Jesus, you do know that Rockford amplifiers are CURRENT HOGS! Also it was probably already mentioned BUT is your ground connection onto the actual frame?

    No it's on the chassis.

    weather or not it actually does is an entirely diffrent story.
    did you change the pulley on the alternator by chance ?

    I don't remember what the 310A peak was at, but the alternator is from Mike Singer and he's very reputable in the HO alt game so I trust his work. The alt was the highest end alt he could make for my vehicle. And the alt came with a smaller pulley on it already. I was thinking about changing the size of the belt but I havent had any issues with slipping or voltage falling sporadically, so I didn't bother.

    Re: Massive voltage drop even with 310A alternator!!

    just for shoots and giggles - can you take your alternator to autozone or whrever and have them bench test it for you ?
    maby something wiggled loose in shipping or who knows
    it be good to have proof it works like its suposed to - so you can rule that out as one potential cause of this issue your having.

    fyi - i always ground my amp to frame of my viechle - but then also do a negative run to the battery from the amp ground. why ? because the same reason big 3 works

    Would that mean I'd end up having to drill a big hole through my trunk to the outside?

    no
    just drill a 1/4" hole right thru your trunk.
    take your 1/4" drill bit to your local hardware store and find a bolt thats just small enough around to fit thru the size hole you made.
    in your trunk - go negative thru to the amp - and on the underside of the car catch the bolt with the battery - run going up front.
    then use a lock nut and tighten that crap up good.

    Fix your power and ground runs.. problem solved

    Make sure all of your terminals are properly done and all grounds are in adequate spots. CCA or OFC doesn't matter as long as the wire can handle the proper amount of current and the wire is covered to prevent oxidation. 2 runs of CCA has less resistance than a single run of OFC, and is generally cheaper
