rms question

[bristabrock 0]

ok im buyin a 2003 audiobahn immortal 18 from my friend for really cheap, i know they are by far the best but i need something for my crappy truck for a little while, but i was wondering how much i should put on it, i know he had a 4000 watt legacy (crap) but it hit pretty hard, does anyone know how much they actually put out, and if anyone knows how much can i actually put on it, i read they are 2250 rms and 4000 peak, but i want to push it to its max

Without a model number, we can't do anything for you. I sincerely doubt it was anywhere near 2000w~ though.

lol, even with a model number it will be a guess. Your ears will tell you when you have gone too far.

I would guess maybe 1000 watts on that legacy. I figure 4000 is a max rating, so knock it in half for the RMS rating- 2000. then knock that in half because it's legacy and that number is likely rated not only overly high in the first place, but with 18 volts at 65% distortion for 1/10th of a second.

aight thanks for the info on the amp, that really helps

Those Immortals are not designed to be used for music for one so it will sound terrible.

The original immortals are a different story.

The power ratings Audiobahn gives is musical peak power.

This means, do not put more than a 2200w amp on it unclipped.

That Legacy is maybe 500 RMS. Got gut pics?

[bristabrock 0]

no sorry i cant find any pics of the guts but it is a Legacy LA2259 and also, i read an article stating that the "old" or "original" immortals are the ones from 2003 or so with a double layer kevlar cone, which is what i have, but what do you mean 2200 watts "unclipped", also does anyone know what ohm the coils are, i know its dual coil, just not sure what ohm, and i also read that the original version of the immortal was deigned with some help from some of the guys from dd audio can anyone confirm that?

[johnecon2001 82]

You can use a DMM to find the ohm load on each coil of the A-bahn

and lol, I just found the "specs" on that amp.

2 x 300w @ 4 ohms

2 x 450w @ 2 ohms

Stable from 2-4ohms stereo and 4-8ohms mono

hahaha, wow, and that thing was pretty loud in his truck, but that could be why its barely broken in, but also, where can i find a DMM to use?

This one will work fine
