  1. take the glass out and bring it to a metal shop to make a plug. then get it welded in and paint over it. you're just going to destroy it.
  2. anywhere you want, just keep them away from any power wires. if any electromagnetic field is near those crossovers, you'll have noise in your system.
  3. most companies, not all, just slap parts together with hopes and prayers. if you call or email companies that actually design their own products, they will provide you with the t/s parameters. some will be off a bit. part of the reason why some of those t/s parameters will be off is b/c very, very few actually build all their subs in house. that's another part that plays the role of why companies don't release the t/s parameters.
  4. fuses go within 18" of every power source (battery/alternator). if you only do it at the battery, then the other side is still live.
  5. keep in mind that the DD1 is measuring audio signal. just because you are hearing distortion doesn't necessarily mean you have a distorted audio signal. your speakers may be creating the distortion. also keep in mind that setting your gains with the DD1 is getting the most power out of your amp without distortion. example, if you set your gain to 34 without the red light but it comes on at 35. if you boost a frequency, it's like turning the volume up to 35 on that one frequency.
  6. getting enough even heat to the center of the strands is very difficult. the outer strands get too hot and deform the jacket. the only way I see soldering 8 gauge or larger easily is to use the terminals that are like cups where you can fill the cup of the terminal with solder and heat it up then dip the wire into it. a proper crimp is every bit as good as a good soldered joint.
  7. love to get your thoughts on this since you think the router jig is so expensive https://www.wccaraudio.com/smd-single-fuse-block.html
  8. honestly the price you paid is pretty close to what should be charged for what you would have got. however there are things I question about the build as well as the "windy" and "hair trick" promise. the cuts seem to not be from a jigsaw for the sub woofer cut out. the internal bracing doesn't have rounded edges. where the joints are, there is no seal from either wood glue, silicone, or caulk. as for the windy part, they should be able to show you a box design with port velocity. for the hair trick part, that's a promise too far considering it's a single 15. while it's more common to see a hair trick on 5k, it's not so common to do a hair trick on a single 15. also a hair trick is what in this promise?, i'm thinking making a chic look like Medusa not the tips of a girls hair raise up a little.
  9. the Audiocontrol LC7i is just a signal summing line output converter. it has no sound processing power outside of Accubass which is solely for bass roll off from an OEM deck. I'd move from the LC7i to an LCQ-1 or DQ-61 or DM608. based on what you have I'd shrink that box down to 1 cubic foot net volume and tune to 30hz.
  10. that's not a thing. it's not a leaver like a diving board. it's like a barbell, it's moves up and down. if it's 8ft long or 5ft long it's travel is still up x distance and down at x distance. if this had any factual basis then everyone would have small subs.
  11. 6 12s Anthem https://youtu.be/LHvD210aQ8A 4 15s Song (2:30) https://youtu.be/9iCd6UHR-3I honestly though, the 4 15s has more cone area. if power is equal I'd lean toward cone area.
  12. volume lowers that db every octave. so 100hz hpf 12db. at 100hz it's 0db, at 50hz it's -12db, at 25hz it's -24db.
  13. let's find out what type of noise you have. when the noise is present does it change freq or pitch when you use other things (like lock/unlock, window up or down) in the car or push the gas pedal?
  14. i got Lasik done over 10 years ago. 15/20 was the correction. I couldn't see anything clearly after an arms distance before the surgery. I'm only 5'8" so that's not that far from my head. I still see 15/20. I get my eyes checked every year and it's been the same since. my wife got her's to 20/20 and her eyesight was slightly better than mine. she got her's done the year after me. I got mine done in 2007, her's in 2008. Dr. Brint did our procedures. yes he was more expensive than anyone else but he's the guy that created the procedure. I've never heard of an eye transplant, so I wasn't going to take any chances on having this done wrong or having it done again.
