ohm load do i have a clue?

I thought I had it until this.

Why would two 8 ohm subs be 190x2 @ 2 ohms?

And why would it be 95W@ 4ohm per sub when the amp says 125W@ 4 ohm x2?

Decent head unit Kenwood MP 345u. Decent amp Pioneer GM-5100t. Decent subs RF P1's or RF P2's. I also have a sealed box with the right specs for these subs, and a vented box with the right specs for these subs.

I am trying very hard to do this right, and to maximise everything in the system to it's full potential.

Nevermind. I was just reading it wrong. I understand. I was just taking the 125W@ 4 (as stated on the amp)and cutting it in half to get 75.

because when i answered that, your question was regarding hooking up two 8 ohm subs SEPERATELY in stereo mode (one to each channel) when you do one sub to one channel the load on the amp will be whatever the ohms of the sub areJL HD 1200.1 $700

Last question I guess.

Will this minimal amount of power (<500W) require the use of a capacitor?

i do not believe in caps personally. because it is just adding another load on your alternator. now, when the amp draws power from the cap, the cap must charge back up which is the job of the alternator. now your alt. is charging both the battery and cap. but anyway, if you have a good electrical system really, you shouldn't need a cap. you may get a cap though if your lights start dimming and such, but like i said it's just another load on your alternator, which in the longrun will damage your alt. but if you do get one make sure it has a quick discharge rateJL HD 1200.1 $700

Thanks sq, really, you have been a ton of help.

Since you seem to be very good at this, I have a challenge if you think you are up to it. I have a mid '90's Lanzar OptiDrivePlus 50 that has been in use non stop since I got it second hand in '97. I can find next to nothing about this amp (other than Ampguts saying it is 25Wx2@ 2 / 50Wx1@ 4. This just can't be anywhere near true. I know that old school Lanzars are under-rated, but the old, small, Lanzar pushes 1 or 2 12's better than this Pioneer 760W and better than my old school RF Puch 250.2 It has pushed everything that I have ever thrown at it with absolutely 0 issues. Any way to find out what it is actually capable of? How stable it is?

Sorry, 25Wx2@ 4 / 50Wx1@ 4Just your average 12 second station wagon.

this isn't the model number of the amp is it? Lanzar OptiDrivePlus 50 i don't think it is. like jl's amps are jl 1000.1/v2 etc. look at the model number somewhere on the amp (might even be inside the amp) and look it up online. otherwise you can perform a bench test (to find true rms wattage) and I unfortunately do not know how to do thatJL HD 1200.1 $700
