  1. Because of the hype from my co-workers, people on the Internet, listening to one of my co-workers SA8 (which sounded amazing I might add), and Brian from Sundown, I was hoping a deeper and louder bass than my previous subs. Especially considering the price I paid for them.

    Truth to be told, I'm feeling a little discouraged at the moment for choosing these SD2s. I'm really hoping that I'm just being a drama queen and don't have these tuned right but, honestly I'm losing faith.

    I bet you it will sound much better if you change your box...how are your fab skills...I would do ported...

  2. Update:

    I swapped amps from the corolla with my truck.

    Going from a GM-D8601 that pushed 800RMSx1 @ 1ohm stable to:

    GM-D9601 that is pushing 1200RMSx1 @ 1ohm stable.

    That made a little improvement but I still do not fee like the subs are producing what they could be. Any suggestions? Anyone?

    Could my process of tuning be incorrect?

    I am using the 40hz Shine test tone. It is being played from my phone via Bluetooth streaming. Before playing the test tone, set my H/U to volume 25 (full is 40 and setting to 30 just seems too loud for the speakers) I ensured that the crossover on the H/U is off, and the amp's LPF is turned all the way down to 40hz. From there, I set the gain accordingly. When adjusting the amps LPF 80hz to 100hz seems to make the subs respond the best. At the H/U side, I try to match as best as possible. It seems that 80hz with -18db sounds the best for these subs but their "loudness" lacks.

    Is there a better way to go about this?

    What kind of sound do you expect it to produce?

  3. Imagine for a second that you went to the local drag strip. You watched cars for years going in the 9s, 10s, 11s, and 12s. Then, someone says . . . "You know these cars are going faster here than at any other track . . . hmmm." They roll the track and determine that it really isn't 1,320 feet from the lights to the finish line . . . it's only 1,270 feet. That makes EVERY single time ever recorded at that track worthless. In addition, it really isn't possible to say with any certainty that one car is still a tenth faster than another because the car that was a tenth slower may have actually been able to make some (or all) of that up in the last 50 feet.

    We, as car audio enthusiasts, should question methods that are questionable. Especially whey they defy the laws of physics.

    in regards to this analogy, when it comes to the "drag strip", yes it would be true that then every car that ever raced there would be null, but only BECAUSE there are other tracks in which the distance from start to finish was actually different/all the same there. But when it comes to the car audio world, every car that has ever had to be clamped for USACI or dbdrag in order to compete, had to use something in order to clamp all these amps. And a lot of these classes require they are clamped at the time of the run. Every time i have ever been to a competition, they used a clamp test with a multimeter and a clamp, i have never seen an AD-1 at an officially sponsored event. so if every record ever set, on every track ever, was wrong, then technically they were all still judged on the same scale, so although the clamp test is incorrect in determining true RMS power output, i don't think its right to say all past accomplishment set by these competitors should be nullified or something to that degree, because all were... incorrectly... judged the same at least.

    I just realized that this post had been revived a few times, and maybe there have been advances i have missed, but hopefully it still gets seen
