alpine mrd m501

Hello all, I'm new to this forum but I would like to ask some advice from any and all who know this amplifier. I recently isnstalled one in my 2001 accord coupe paired up to a jl 12w3v2 (it wasn't my first choice but whatever) and I was wondering if anyone could tell me how to tune it because right now it sounds awful. Any advice would be greatly appreciated. Thanks.

Check it out.

Talk to Alpine Guy.

Its near impossible to instruct you on how to set that amp up over the computer, you would have to uderstand the functions and adjust them by ear.  Do you have an alpine dealer near by?

Look at my post on the " Alpin break in " post.

I have a minimal understanding of the functions on the amp but when I was playing with the gains and such on it I really couldn't notice an audible difference maybe there was some sort of delay. I miss knobs so very much.

what's wrong with the sound now??

Post more details please!

I actually just got on of these. I am getting it professionally installed. I guess they will listen to it and change what they need to change to make it sound good? Is that usually included with installation of a whole new system? thanks

I curently have two mrd m1001s and a mrv 540. WIth the factory settings my comps and subs sounded crappy, your going to have to tune your amps settings for your speakers.  If the mrd 501 is any like the other v12 alpine amps it's going to be great ..after you make the neccesary setting adjustments.

I figured out that a lot of the problem was with the head unit I didn't have the EQ set right but it still doesn't sound near as good as it should (or as loud). I was just wondering if any of you guys had some settings that you have used or know of to maximize this setup's potential.

Oh btw the tuning should be included in the instalation but some places charge seperately for that, the one near here charges $50.00 an hour for tuning that's kinda why I'd rather do it on my own that and if I ever have to re-tune it I don't wanna pay to have it done twice ya know.

Most of the problems I had with the sound was that it sounded muddy and very distorted. I fixed a lot of this by turning off the media xpander, messing with the deck's eq and low pass filter. But I still don't think that this is the best that this setup can sound. I used to have a 12' xplod that I remember being louder and I hated that sub. I hate paying for these sorts of things especially since I'm currently saving up for a set of type x components so any help would be greatly appreciated. Thanks.

hi there

i recently bought two Alpine type R 12" subs and to power them I got the alpine MRD-M501. Everything is all wired up, but the problem is that when i turn the music up to about 14-17 (usually i listen to drum n bass), after about 10 - 15 seconds, much to my annoyance the amp completely turns off. I am just wondering if anyone knows what is causing this - would it be that im trying to push too much power into the amp and it just cant handle it?
should i fine tune the amp so it doesnt ask for so much power? I have tried to dampen down the bass somewhat but it is still occuring.

i had a few issues with the grounding at first, but i have since grounded both my amps (i have another V-power amp running four type S splits) at the same point and this seems to have fixed the situation. Any help on this matter would be greatly appreciated!!!!!!

I think I have figured out one of the problems I'm having as far as power is concerned I pulled the sub out of the box today and realized that when the installer put it into my room mates car he had wired it up in series. I was wondering if it would be dangerous to wire it up parallel. I know that's a lot of power to be pushing to one speaker but the measly 275 watts that it's getting now doesn't seem to be doing a whole lot. What do you guys think?
