ItsAJeepThing Posted May 12, 2011 Report Share Posted May 12, 2011 (edited) 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 duct 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?

ItsAJeepThing Posted May 12, 2011 Author Report Share Posted May 12, 2011 Yes the setup is just for burps. Quote Link to comment Share on other sites More sharing options...
That1Kid Posted May 12, 2011 Report Share Posted May 12, 2011 There is a thread here somewhere with lots of spl tips. 45s in all corners isn't a good idea according the the thread iirc Quote -98' Ford Expedition (Rest in Peace) -AVH-P3300BT -Crescendo BC5500 -4 18" DC m2 Level 3.

ItsAJeepThing Posted May 12, 2011 Author Report Share Posted May 12, 2011 We had it clamped the same day, the ohms rose to about 5 and it did only about ~1600 watts. So with impedence rise, if we did wire down to .5 ohm the amp really wouldnt ever see it. Is it still a bad idea? Quote Link to comment Share on other sites More sharing options...

Is it still a bad idea? no actually. it seems to make the most sense to try it Quote -Matt2005 Dodge Magnum RTJVC KD-AVX1 2 PPI S580.2 Obsidian Audio ST1 Horn Tweeters PRV 8MB450s Audio Legion 3500.1D 2 RE MT 18s 360 ah LiFePO4 BatterySHCA 2/0 155.2 @ 29 hzKicker CVR 15's buildDD 3512e buildMini T-Line Build(6) 8s BuildNightshade 15s Wall BuildMagnum AB XFL 12s BuildNewest Magnum Build Link to comment Share on other sites More sharing options...
MatthewMartin Posted May 12, 2011 Report Share Posted May 12, 2011 (edited) This is the OPs buddy. The port is pretty large the way it is. I don't remember the port area off the top of my head but I know its more than enough for an SPL setup. I had another thought. If we run the ap3000d, we must compete in the stock 601-1800 class. We have an Ap1500 that we could use instead dropping us down to the stock 0-600 class. From here we could run the 1500 at .5 ohm to stay competitive. Thoughts?
