By the way I wasn't saying your were vomiting information I was mearly stating a general rule, as for proof on the xovers its not for me to prove myself right is up to you to prove me wrong, but I'm sure you've got better things do to, know I was just trying to help the guy out without mass confusion. But thanks for the input

im not "vomiting" information. show me proof of a crossover that cuts out LOW FREQUENCIES so the midbass driver does not get damaged from overexcursion. his headunit wont let out low frequencies if he puts the HPF on. your information is super misleading, btw. how does this make sense? why would you want the crossover frequency to be all the way up on the amp? depending on the amp, it will cut off a good usable chunk of the response band and make your speakers sound like shit because there will be no midrange. I suggested he run the amp on full pass btw

Humm that's odd cause he understood an amp only amplifys the input signal if his head unit is set to send a signal from 80-20k it doesn't matter how low the lp filter is set on the amp will never produce a note lower than 80hz or higher than 20khz

He's using crossovers provided with the components which cut out any freqs the drivers are not ment for I know mine do reguardless of input signal and its better to start people in the right direction than to vomit information so the get confused or discouraged plus his HU set up won't let any lower freqs out so bottoming out is not a factor but distortion on the other hand is all in the HU volume max and amp gain settings, wasn't tryin to overload the guy but I'm sure he will be alright as long as he uses his crossovers and keeps the gains at a respectable level *I stand corrected my crossovers freq rang is 55hz to 20khz so they do cut out the low bass but not all the bass

Wish I could say the same my time will come

If you can afford it sundown all the way that or RF bdcp series I'm not gonna knock Hifonics old bx series are about the best bang for the buck and are cea certified I know I own a bx1605d and a bx1500d but both I had the update the caps and input transistors due to below par factory installed one but what can I say a true 1600wrms amp for $100 its hard to beat. But sundown on the other hand... saz1500 is a 1900wrms amp would love to get a couple of those that are blown cheap

Wondering what's a good port volume for 2 sa15s box is currently 6ft^3 30.5hz

If your running components or 6x9 on cross overs you can just turn you ferqs settings all the way up let the crossovers do their job as for gains if your HU RCAs puts out 4,5,6v then you gains should be fairly low due to I high input signal but Alpine makes some good stuff so you should be ok as for xover location I mounted mine in the door with the speakers just forward of the window track with the thick double sided foam tape just be sure you clean both the crossover and mounting location with isp alcohol first for a good bond and mount the where the heat from the summers sun doesn't make gravity/vibration work against you trust me last thing you want to do is tear panels off again cause your electronics are bumbling around

Active or passive crossover that go between your speaker wires and speakers

Are running any "in line" xovers? If your powering components with xovers like my bostons the you can run it fp or fullpass cause the xovers will kill any freqs the driver isn't designed for

Is the amp powering subs? Mids? Tweets?

Iwhat are you running?

You can also use a tweeter on a xover to check for clipping due to harmonics but just to be safe have your stuff scoped or set with a dd-1 when they are shipped that is

All the way up... I.E. turned the the highest frequency settings but lower than the xover out of the HU will only play the freqs the amps xover is set to... make sense?

If you set the xover on the HU the ones on the amp can be all the way up and its only going to play the frequency the HU sends

Well after writing a hearty reply and some forum failure. I will just say after he breaks even expense wise and gets the rave reviews this product needs then the bank won't matter it will pour in on a regular

lol at some of the replies in here. After upfront expenses and RnD 30k isn't really 30k but he's getting his product out there and more exposure = more customers and that my friend is where the bank is going to come from, after he sells about 500 of these thing he's gonna be one happy dude, and are these things made in USA? Or just assembled here? Let's see, in the one pic, there are about 200 units at 150ish each = around 30k...NICE!!! Make that money.
