[QUOTE="vario, post: 4971578, member: 583966"] both amps claim 500 watts @ 2 ohm x1 (its a mono block). Subs are DVC Infinity 10's with 4 ohm per coil wired to 2 ohm, not that it matters as I have them disconnected when testing voltage of course. Best voltage I can get with no bass boost and no distortion is actually around 16 volts @ 2 ohm which seems really pathetic. Head unit settings: Flat EQ. SLA (source line amp) +4. Sub: LPF 100 hz sla +6. Bass Boost : 0 Fade 0 HPF: 50 hz Grounds and power wire are good, IMO. Power wire is 4 gauge. It goes into a fuse block that splits into three 8 gauge wire, each about a foot long, 1 to each amp and each amp is grounded on 8 gauge to a central block that grounds to the chassis, also about a foot long per ground wire. I can take a picture later if that helps its a pretty simple wiring setup. Its a civic with a stock alternator. Think that could do it? Or are cadence junk? I have my doubts about cadence quality. I bought both amps for $50 each. How do I test the input voltage? Measure off the battery? [/QUOTE]
