Alpine mrp-m1000 1ohm stable?

is the alpine mrp-m1000 amp 1ohms stable?....i guy i'm building a box for just went out and bought this amp, and two 10"type r's....that are dual 4's....so i can either wire them at 1 or 4ohms.....and i'm thinking after imp. rise the amp should see a 1ohm load around 2 ohms...(which the amp is rated at 1000wrms)....so would i be ok to wire his subs at 1ohms....or should i just wire them to 4 ohms, and let them see only around 600wrms

nope, it is 2 ohm stable

what would happen if i did wired the subs to 1 ohm....would the amp see it diferently after impedance rise?

It isnt meant to handle a 1 ohm load. It could overheat, or possibly blow the amp.

They are picky with anything below 2 ohms. Tend to go into protect fairly quick when at 1 ohm.

I sold mine to a guy running it at 1.5 ohms successfully, not sure about 1. I never ran mine below 2

well i think i'll try wiring it at 1 ohms....and i'll run the wires out the back of the box so that if it goes in to protect i'll make it where i can re wire them to 4ohms....and they'll just be underpowered....unless i hear of anybody blowing their amp from running it at 1ohms

Yeah, your not gonna be happy when it does either....I mean, There clearly is a reason why alpine list it not to be run at 1 ohm...

^^^...yeah i guess ur right....i'll just see how he likes it being ran at 4ohms.....i noticed how the amp has no ssf....should i have to worry about the sub bottoming out below tuning

Whats the box tuned to, and is it ported or sealed? Just don't go playing some crazy shit like a 40-0 hz sweep at full power, cause once it hits like 23hz, bottoming will happen. Other than that, i wouldnt worry about bottoming out, its easy to hear as well...

its going under the back seat of his chevy 2500 extended cab.....i built it around 2.3cubes after all displacements tuned at around 34hz.....my specs aren't 100% accurate, due to the hump in the middle of the floor (i just calculated the volume disp. the best i could)....with the subs behind firing forward (at the passenger seat)...and port firing at driver's side (back door)...

Youll be fine.. =)

alright i appreciate it man....i just want the customer to be happy...lol

LOL, i thought this was for you. But yeah, keep that shit at 4 ohm, and don't wire at 1 ohm, or customer will be happy at first, then very very angry...., haha.

It has a subsonic filter - it's fixed at 15hz, 24db/octave
