Im looking at purchasing RCA cables and amp wiring kit for my next system, last time i went with the kicker 0g kit and its doing the job but it was over 100$, should i go with another kicker kit or will a cheaper kit be fine? Like cadence for example? their 3000w kits are only 60$. What about RCAs? You guys that are all about SQ and whatnot, do you use any special rcas besides like gold plated ones?
