On those amps just make sure whoever does it knows what they are doing. Make sure they don't run a long chassis ground. Keep it under 12 inches. Also run your power and audio signal on opposite sides. Should be done always with any amp, but d class Memphis amps are really phinnicky(or however it is spelled)lol. Also use at least a 4 gauge power other people will say 10 or 8 will work and it will, however it is always better not to half a** your installs. Hope I was of some help.
