thanks to all that have helped in the past. but now it is about time to buy everything, and have some shop put it in...

i want to stick with alpine... i have headunit, type-s components, type-s full rangers... so amp and sub(s) will be alpine as well...

for the amp, im thinking the MRD-301:
175 watts RMS x 1 at 4 ohms
350 watts RMS x 1 at 2 ohms (it is 2ohm stable)

now, i can run 175w to one type-s 12" which is rated at 300rms, or 350w to it...

since it is 2ohm stable should i use the power that i have? or will it shorten the life of the amp?

if i go with 350w, i could let two subs share it (175w each). would that prolong the life of the sub(s)?

so basically, heres the options...

175w @ 4 or 350w @ 2?

if 175w, ill run it to one 2ohm dvc 12"...

if 350w, should i run it to one 4ohm dvc 12"? or two 2ohm dvc 12"s?

i know what i want, i just don't know what would be the best way to set it up...

thanks again everyone...

think of it this way...

Say your amp does 1-4 ohms @ full power like mine (1200rms) . So you would want to wire your subs to 4ohms so that it wont put as much stress on your alternator and battery. Lowering the impediance on the subs will not hurt the subs unless you lower it to an unstable ohm load. Your subs can handle what ever your AMP will support. My suggestion if you dont have caps or a good battery find a amp that can be put out full power at 4 ohms. For sub wiring options you can either have 2 DVC @ 2 ohms or 2 DVC @ 4ohms Neither of them are harmfull to the amp. But i would suggest running at 4 ohms unless you plan on buying a cap and a new battery.

i am getting that same amp but with type R subs {big mabye unless i check out the daytons or until shivas are back}

that amp is 320@14.4 volts. the box says 350. neways if you have 2 12s and are not runing it at 2ohms your not giving thoses subs any kind of power at 4ohms. i mean its 300 rms and your giving it about half. what i wll be doing is gettting too of those amps and runing it at 2ohms on each sub. that amp is 2ohm stable so you dont have to worry about it "not lasting long."

if you run it at 350 rms to one sub then all you have to do is lower the gains.

edit i mean one mono amp on one sub. btw you might as well get the typeRs i mean the type s are kinda entry level products.

Yeah you don't have to worry too much about wearing out the subs running the setup 2 Da Max just put up. Most of your actual wear and tear comes from pushing your subs to the point it's distorted.

I've been running my 4ohm RF punch z's for almost 3 years now at 2 ohms. And they still sound great. That's because I don't push them to the point they're distorted.

Also, 2 Da Max's setup would be a lot better. If you try running 300 watt RMS subs at 175 watts, you'll burn out your amp before too long. Because you'll be cranking it up just to get the subs to move. Go with 2 mono amps, that have a power rating that matches or beats the recommended RMS for the subs.

so it's more stress on battery, amp, and subs running at lower ohms? obviously more the more distortion is pushed...

therefore, whatever i get, just run at 4ohms?
