[QUOTE="El Ropo, post: 1594457, member: 561863"] He's got two perfectly kick arse subs, If I were him, I'd keep the subs, and just build a proper sized sealed box. As far as what to set the gains to, I'd say anywhere between 900 and 1000 watts @ 2 ohms is perfectly safe. sq rt of (900x2)=42.43 volts AC, sq rt of (1000x2)=44.72 volts AC. Make sure you use a 0db test tone, not -3 db or -6db ones that are floating around. Also, do not use tones created by NCH tone gererator, they are -12db, way too quiet, and you end up setting your gains way too high. You do have a trunk car, and after reading the owner's manual for that deck, I still can't be sure it it has time alignment when in stereo mode. For sure, it does in 5.1 mode (nice). There might be a phase adjustment in your setup somewhere too, but the manual wasn't too clear on all of that. If all else fails, you can just try turning the sub box around. Oh, and as far as putting 2 x 4s in the box to fill up space, I calculate how many inches of 2 x 4s I need, then cut in pieces to fit on the bottom of the box. Then I use Industrial strength Liquid nails to glue the chunks of wood to inside of box. Just doing some quick calculations, your box is 1 cubic foot too large, that means you need to fill up about 1728 CUBIC INCHES of space. That's a friggin lot of 2 x 4s, like 27 ft. worth, good luck lol [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] [/QUOTE]
