is it OK?
i have 2 12" subs (8oms) and an amp that makes them bottom out. i was wondering if i could run those two subs plus 2 6X9" (4oms) in parallel. Will more oms hurt my amp? I know i will lose watts with more oms.

kinda confused by your post. are each of the subs 8 ohms, or are they each 4 ohms wired in series resulting in an 8 ohm load?
if they are each 8 ohms, then right now you're running them in parallel for a single 4ohm load on your amp.
if you add on another set of 4ohm 6x9's all in parallel, your amp is gonna be seeing a 1.33ohm load...and unless you have an epic or extremely high quality amp, it's gonna end up clipping or shutting off a lot...which you don't want. Plus it will a lot of current and put high strain on your electrical system.
Do you only have a 2 channel amp? Your approach doesn't make much sense anyways from the logical perspective unless you're planning on using passive crossovers on each speaker line. Because you don't want your 6x9's having only subwoofer frequencies passed to them and you dont want your subs having mid frequencies passed to them either. Just get a seperate amp to run your front/rear stage and one dedicated to your subs...or a high powered 5 or 6 channel amp.

yes my subs are 8 oms apiece and the 6X9" are 4oms apiece. so if i run both Subs and 6X9" at the same time it will have 1.33 oms? whats the formula for that?
also i have a 2 channel amp. so what if i wire the two in parallel and the two 6X9's in series. will it still cut off? o and the 6X9's are sub drives

honestly, don't even bother
but there are ohm calculators online..and yes its a 1.33 ohm load, which I doubt your amp will support unless it's an upper class amp
even if the 6x9's are psuedo sub drivers, they're not gonna be hitting 45hz and below cleanly and higher volumes. you can get good 4 channel amps for like 100 bucks nowadays, do it the right way. you dont want to run your subs and other drivers on the same channels...its just not gonna sound right sharing gains /frequencies with smaller drivers.
