Peter Idsinga:
I Havethe subs wired in 4 ohm, and am pushing about 125w RMS, into them when I ohmed them out, they are putting out just enough bass, yet not enough to ever blow them. They are not barely @ 1/3 gain. I could crank it but why they are just 2 comp SVC 10's.
The amp's are all individually wired and the grounds are all straight to the Battery, the power's are 0ga, to the fuse block the 4ga into each amp.
I have the power to the unit from the power strip it is getting a constant 12v, I added an additional 8ga wire from Batter to the strip, and the deck is grounded to the strip as well there is a jumper ground 12g from the main amp to the ground strip on the factory block.
Battery wise I have 2 brand new group29's in there the boat only had 1 group 24 to start.
I am confused I thought this was your system (took this from your first post):
6x9's = Kicker KS6930 3 ways x's 2 sets
Subs = Kicker comp CVX10 1500 watt ea x's 2
6.5 coax = Kicker KS600 2 way 1 set
6.5 component = Kicker KS650.2 x's 2 set's
4 channel amps = Rockford Fosgate Power 500X x's 2
Mono block = Kicker ZX1000.1
I was assuming you have the kicker ZX1000.1 (huge amp as in dimensions) powering the subs. Those CVX10s . . . if I remember correctly are 600 WATTS RMS each. They would thump very nice and clean in a sealed box with that amp.
I am not sure what you mean by strip.
Here is what I would do, I would get a 1/0 to 4 gauge out dist block. 1/0 can handle up to 325 AMPs of draw . . which brings up a point did you use a fuse block within 18" inches of the battery? Put the dist block within the 3 foot reccomendation for the step down wiring to each amp. This will save a ton of money on that 1/0 wiring. Then you can easily power all the equipment from 1 battery.
Then do the same for the ground. If you are splitting the power between batteries, I would bet that is where you are picking up SOME noise. If you have all your amps on the same power source and same ground, plus ground your head unit back to the same location, this will help with isolation.
Also, I did not catch your battery setup. Are you running parallel or a battery switch? With that much power, I am assuming you have them in parallel so you can have a longer amp/hour life for your stereo. I added a 200 AH battery for my system, plus I have a regualr marine battery to start the boat. Then when I want to charge my battery, I simply switch the perko and pull skiers for a while and charge up my monster battery. Of course I put the chargers one when I leave it in dry dock for the night/week.
Anyhow, summary. Power and Ground everything to the same battery. I am talking about your amps and head unit. Primary wire is dirt cheap, I would run it all the way to the battery. By not isolating the ground that his another place for noise to come in.
Another potential is you are overdriving your alternator and it is damaged and introducing a lot of noise into your power system. This is rare but does happen.
Hope some of this helps.
