dodge ram help.. mad voltage drop

[artgraham]

I have an 05 ram 1500 with a 160 amp stock alternator. I am running 2 cadence a7 hc amps each at 1 ohm. powering 1 dc audio level 3 10" sub per amp. Both amps are fed buy a single run of monster cable OFC 4 gauge. With all that said...where is all the voltage drop and light / dash dimming coming from and how do I fix it?

Thanks

Not familiar with those amps, how much power are you drawing? Did you do the big 3?

Each of the amps have been clamped at 1450+ at 14 volts at 1 ohm. I have using seat bolts for ground points. The drop is as lo as 10 volts to the point the amps protect. Both at the dame time

So your at 2900rms at 14volts and your running 4ga???? Upgrade, upgrade and did I mention upgrade....a run of 0ga to each. You need a HO alt and an xtra battery at least. Your KILLING your alt and battery right now.

He will kill the amps first when they drop below 11v

I did the same thing as Varinabassing. Everything had to go to the frame and massive wire. The electrical in a Ram is very finicky. I have literally taken EVERY bolt out of my truck at least once, so if you have any particular or specific questions about your truck, PM me. I would be very happy to help you Bro!

I will start with a second run of wire and new ground points. Will any frame bolt work?
