cgrez33 Posted April 12, 2011 Report Share Posted April 12, 2011 I'll keep it simple. I have 50' of KNU CCA wire, which I ordered believing it was the OCA wire. What is the maximum power handling rating for CCA? If I'm running more than 3k watts, should I return it and get something better?

nickers Posted April 13, 2011 Report Share Posted April 13, 2011 i just ordered 2 50' spools of KCA and they just came today. they are rated to 250 amps. so it really depends on home many runs you put to your rear bank.

baaudio Posted April 13, 2011 Report Share Posted April 13, 2011 generally speaking, 1/0 awg ofc wire is rated for 300 amps, 1/0 awg cca wire is rated for 250. for your 3000 rms i would recommend doing two runs to the rear if possible. only 1 run may choke the system some Quote Team NWSPL baaudio Build Log 2001 GMC Sierra walkthrough 4 Mechman Elite 370s, 10 AGM batteries, 3 Crossfire XS v2 18s, Crossfire 8k Link to comment Share on other sites More sharing options...
Kevin Posted April 13, 2011 Report Share Posted April 13, 2011 What size is the wire and what class is your amplifier? Quote Link to comment Share on other sites More sharing options...

Like the big 3, Ofc is what I'm using than cca. Quote How do the Japanese feel about bass?You know that since 03/11/11 Progene? I just saw that stuff on CNN.

carlosg_313 Posted April 13, 2011 Report Share Posted April 13, 2011 (edited) What size is the wire and what class is your amplifier? It's really nothing about class, its more of how much rms is the amp rated for. Edited April 13, 2011 by carlosg_313 Quote How do the Japanese feel about bass?You know that since 03/11/11 Progene?

Kevin Posted April 13, 2011 Report Share Posted April 13, 2011 (edited) What size is the wire and what class is your amplifier? It's really nothing about class, its more of how much rms is the amp rated for. A Class D amplifier is more efficient compared to a Class A/B amplifier therefore you can get more power out using a Class D amplifier. With a Class D amplifier one run of 1/0 gauge wire may suffice but with a Class A/B amplifier you will definitely need two runs of 1/0 gauge.

cgrez33 Posted April 13, 2011 Author Report Share Posted April 13, 2011 I decided, I'm going to stay with the CCA, and just do multiple runs. In the future may upgrade to some 2/0 welding cable, see how that goes. Thanks for your help! -Chris.
