do i need to upgrade wiring with 800 watt rms?

[johnno010684]

hey i have a pioneer 4 way running car speakers 600 watt, and a 100 watt running a kicker sub. i have two power cables coming from battery and bth are 8ga do i need to upgrade the big three? and also will my sub 125rms handle a bigger amp 190watt?

What are the model numbers of your amplifiers? I can't really understand your first post.
Also, what are the model numbers of the components you are running from your amplifiers?

I would go 4 gauge minimum. As said post up some model numbers as the numbers your giving seem to be maximum ratings.

Sorry was kind of in a rush before lunch. I'll post up model numbers of both amps in next hour

id do the big three even if you dont need to, the higher voltage the better

lol forget about that ^ didnt read u were only wanted to run >200rms

[johnno010684]

Ok so the 4 ch pioneer amp is gm-6400f, the kicker amp running the sub is dx 100.2. The alpine amp which I am wondering if I can run the sub is mrp-t130. Oh and the sub is a 12" kicker 375 watts peak 125 Rms 4 ohm

sub is kicker ves12

i havent got the boxes for the 6x9's or the splits in front anymore but im pretty sure the fronts were 80w from memory and 6x9's are 160w

[Nic92]

i think 8 gauge would be enough unless you got it 20+ ft long

ur only pushing out about 370rms so the wiring u already have will b suffient as nic said. and the alpine amp will run that sub fine and it never hurts 2 do the big 3 even on a small system like this.

The big 3 is wasted on a system like this. The stock wire for the alternator charge wire is ~6awg over a ~60cm run. 85 amp alternator. It will be able to keep up fine with this system. As a rule of thumb, keep your engine earths the same size or larger than your main power cable run, 8awg power cable run, the stock earths are already larger than 8awg. There is no real point, unless you plan on upgrading later, you could do it now. I don't imagine you'd see any real difference.
