hey guys just installed amp into my mates car, its a KENWOOD KAC8104D its rated at 1000w max with 500wrmsX1 @ 2 ohms altho it is a monoblock it does have 2 speaker outputs ive got 2 subs connected to each output. i was wondering how much rms i would be getting to each speaker?

It depends on how you have wired it, and the impedance of the subs. Since you have four subs, there are several ways of wiring, resulting in various loads - even moreso if they are dual coil. It's not something you want to stuff up - if the amp is driving an impedance of less than it's rated for, you will be in for trouble.

Each sub is connectd straight to one speaker output and it's a single voice coil but the amp has 2 speaker outputs? How would I run the 2 subs off 2 ohms? Do I use one speaker output and connect 2 subs parralel to it? To makE 2 ohms? Subs are also 4 ohms I do have understanding about car audio but this amps rating only says 1000x1 max I doesn't say the output for x2? But it has 2 speaker outputs? worked it out

The amp's two speaker outputs are paralleled internally. So, with one 4ohm sub on each output, your amp is driving a 2ohm load and should be able to put out 500wrms (250wrms into each sub). Try to forget about 'max' power ratings, they are mostly pointless and irrelevant.

Yeah i found out tday how it worked. I hadn't really worked on many mono blocks. Thanks for the help mate
