Planet audio m2 15''s??

I recently bought two of these fifteens in the svc version off a friend for dirt. I have one in a sealed slant box, and its surprisingly loud for 300 watts (vx400d at 4 ohm). However, it gets real quiet on lower songs, and starts to distort. I set my subsonic and it was a lot better, but it just sounds "muddy". I was wanting to know if it was worth the trouble of building a slot ported box for both of them. Im thinkin it sounded like that becuase of lack of power and shitty box.

maybe your box is too small.

did you match up to the manufacturer's specs? polyfill?

thats the thing, i cant find any specs. All the paperwork had nothing about it, and the site doesnt have ****!! I bought a sealed box for two of them today, im about to see if it sounds better.

1.7 cubic feet per sub is what it wants sealed.

I just put a PA M2 10" in the wife's car in the specified 1.0 cubic foot box aeroport tuned to 40hz and it slams. So the 15's should do really well once they're in a proper enclosure.

i got both of them in a slant sealed box, it sounded funny when i first turned it up. They were making weird noises. I took them out, free aired them on test tones and what not for 3 hours. Put them back in, and they sound perfect, no noises, and hit low and hard. It makes your vision blur on only 600 watts. Roof flex in a hardbody 4 door! never had that before. I was driving down the road, and i played "down on your knees" and i heard like a "warp warp" noise and i reached up and my roof was ****** in.

what is the internal cubic airspace of the box though.. you want it to get as close to spec as possible to get the most out of those subs.

i have 2 zetar 12" svc and love them they are running them off the same amp and have a 3300sf building ratteling

I think these subs are underrated. They are rated for 300 rms each and my amp is rated at 603 watts at 13.0 volts. I have to turn the amp up to half to get good sound out of them, but they arent distorted or anything, and i have a 4v output deck.
