[QUOTE="ItsAJeepThing, post: 7325647, member: 626850"] My friend and I have been working on an spl build to take to a competition coming up. We have an Audiopipe 30001D with a 15" FI BTL. Its in a 93' mazda mx-3. The box is 5 cubes tuned at 45hz. The car peaks at 50hz. The box has 45 degree bracing's in each corner. We have 1/0 running from the battery to a distro block, then 4 gauge to an optima red top then 4 gauge to amp. We are replacing the speaker wire with either 10 or 8 gauge. We also have been told to paint the inside of the box and silicone it. The amp was run at 2 ohms and we are considering doing a half ohm burp. The length from distro block to battery is about 3 feet then another 3 feet to the amp so theres about 6 feet of four gauge. The box will be wrapped in duck tape also. We hooked it up to a termlab today and got a 146.5 in the kick panel with driver door open and sunroof open. when everything was sealed we did around a 143.8. Questions: Will the audiopipe handle a .5ohm burp? Wiring the sub to .5ohm isnt a problem but how would we plug the wires into the audiopipe? Is there anything else we can do to gain db's? [/QUOTE]
