confused by this amp
hello,
here are the specs of my Infinity 611a amp:
• 456W RMS x 1 channel at 4 ohms
• 657W RMS x 1 channel at 2 ohms
• Dynamic power: 761W at 2 ohms
It is connect to a cheap 12 inch sub.
This amp suppose to be a single channel amp, but it has connections for 2 subs.
Does that mean if i hook up 2 subs at 2ohm, i will get 657w per sub? or 657w will the share by those 2 subs?
I feel that my single 12 inch sub is not taking full advantage of this amp.
thanks for reading.

your amp is single channel. it just has 2 sets of terminal for easier speaker hook up.
dynamic power is usually approx. at 14.4v. if you can keep your charging system at that voltage you will get the 761w.
your options for hook up are.
1) hook up one speaker (single 4 ohm or dual 4 ohm wired in parallel for 2 ohm load) to the right side connection
2) hook up two speakers (4 ohms each) to both connections. that will give you 2 ohm load.
3) hook up 2 8 ohm speakers in parallel to each connection for a 2 ohm load.
hooking up a 2 ohm sub on each connection will be a 1 ohm load and will not work.
no matter what your amp is 2 ohm minimum. go below and your amp will shut off due to overheating.
657 watts is gonna be SHARED by all speakers.

go with option one as i stated above your amp is 2 ohm minimum and a single channel even tho you have two connection points (not a two channel amp)
the first option is having each speaker with the voice coils wired in series then both speakers wired together in parallel for a singe 2 ohm load.
the second option is having each speaker with the voice coils wired in parallel already. when you put both those speakers to your single channel amp with 2 terminals, its basically like wiring them both to a single terminal so you will have both speakers wired in parallel after both speakers already wired in parallel on the voice coils so the load will be a 1 ohm load and your amp will not work right.
it will play louder for a lil bit will shut off because it will overheat. i know cuz my kenwood amp did the same thing when i wired it for 2 ohm and it was rated for a 4 ohm load min.
