Sundown or PSI is what his status says under the "Recent Status Updates" column.

Just voted , that would make 20

More details please.

Well there you have it lol

I'm pretty sure Aaron made mention of awaiting a DCON prototype to arrive a few weeks back in someone's build log. Hmmm

Try moving it around and see. As far as the rear deck goes, cutting out two 8 inch holes in the rear deck and modifying the rear deck cover did increase my output across the board but there was still a dip in frequency response above 40hz +. I don't think modding the rear deck would solve your frequency response problem completely as much as it would give you a little more output. If you decide to mod the rear deck just ask yourself if going through the extra trouble of butchering your car is worth what you might gain.

Moving the box around wouldn't hurt. Maybe it'll improve performance, maybe it won't. You won't know for sure until you try.

The fact that you had the kickers tuned to 40hz, the natural design of the cvr's, and the sub/port orientation is probably what gave you that amount of output at 40hz+. You swapped a setup that was loud above 40hz for one that offered better low end and a better overall sound. Its hard to get the best of both worlds out of a real trunk setup due to the amount of sound that is being trapped inside of the trunk. So its either tune low, tune higher, or find some middle ground between low end and upper end extension. Have you modded the trunk any to allow more sound into the cabin? Also I was able to get a 4.4 cube net enclosure in that trunk with 50 square inches of port for my XCON. Sub up port to the side. Experienced the same situation you're in but, I'd rather have my low end extension than a hefty 40hz+ .

What port and sub orientation did you have with the kicker 12's? Was it the same sub up and port back as your current setup? I've noticed in all of trunk setups I've ran that with the cone facing up there is some funky cancelation of certain frequencies in the 40+ range when compared to having the sub firing at the back of the car.

Mmmmk lol.

What made you change amps?

Will you be posting the suggested enclosure specs for the 12 with the bandpass options? Also do you have an idea of the amount of power the bandpass option will take in a vented enclosure?

The frequency response will be different when using the same tuning and different volumes. You could use wood to make up for the difference in airspace. That's the draw back with using removable ports that take up internal volume vs fully external ports.

What I liked about this enclosure was that it played the upper bass lines better compared to being ported in the trunk and no annoying trunk rattles. Never got to test it's full output against the ported enclosure though but for a permanent system in this car I will probably be running this same enclosure style with 2 12's.

Here's an example of what some of the others are recommending as far as a bandpass enclosure ported through the ski-hole/rear armrest.. Build I did last year in my 2002 530i... It was for experimental purposes and not permanent so don't mind the ugliness..

I understand that. Playing devil's advocate I simply said that some people believe clamp test are meaningful. Now as far as should they believe that I never said they should or shouldn't. Was just posting what was said else where about the similarities between AP and this amp. My apologies for any confusion that may have been interpreted. Clamp test are bad mmkay.

Clamp test means nothing.... It depends on who you ask...I'm well aware of the reasons you made that statement though.

Quote posted on another forum... TaylorFade: " I did, in fact, test one of these at Scrapin'. I only had a 1 ohm nominal available. Wired to my caps, car off at 1 ohm... it did 1,450w rising to almost 3 ohms. I don't recall the actual voltage and amperage and my caps were resting ~ 13.3v after the burps. I thought maybe it looked like a couple apsm's in the same case, but the AP's get dirty as shit under load. This amp didn't. It's stayed clean as a whistle. I obviously can't comment on it's durability, what it'd do wired down or how it sounds, but it's doing power. " And another from Shizzz Shizzzon: " just because it makes whatever power clean for the money doesnt make it good. I'm not a hardware engineer but know that better amps will have far more advanced filtering to keep speakers cooler, better internals for abuse, etc.. Heat and power are my 2 main concerns.. Mounted properly and proper monitoring should ensure a long life of any amp. "

Probably comes from the same chinese build house as Audiopipe amps. Very similar board layout with a few different components. Looks like an AP/APCL board with AP mini style heat sink & controls.

From the pictures it looks like the new amps are about half the length of the previous models. From long & slim to short & fat lol.

Beautiful Amps! Respect to IA for out stepping the competition. Definitely interested to learn more about the technology used in these amps.

Cool news. Definitely in for more details.

Sorry you feel that way man. I can't say I know what all the "BS" is that you have dealt with or recognized that level of disrespect , I was just speaking from the threads I've read in your section. Maybe our definition of "BS" is different but as a company owner I have not seen anything said about Flatline that would brother me as much as it seems to be you but we are all different. By all means I am a man of respect personally but when it comes to reading words through a computer screen I usually read with less emotion and more tolerance because of the fact. No disrespect meant here just purely personal opinion .

I don't believe what has been said thus far between members on the forum and Flatline has been intense enough to close shop here already. Many members have welcomed your business and seemed to have faith in your product as mentioned in other threads. Just because some may feel there is a better way to validate the performance of your product it shouldn't excite too much defensive emotion. Especially when the issue isn't with you or your product but something small as the accuracy of a clamp test. The guys here are not the first and only people to dismiss the validity of clamp tests when measuring amplifier output. The beautiful thing about owning your own business is It's your business and at the end of the day you can choose to do as you please. I'm sure most potential customers would be more than happy with seeing clamp test results but for the ones that are more technically informed there might be more to be desired. As a consumer and potential customer I (as well as others im sure) tend to have a higher respect for companies that are honest and professional when defending their product/business vs one that retreats/explodes at the first hint of opposition. Good luck from here on out & hopefully you decide to stick around despite the rough start.

If Audiopipe is what you decide on I'd recommend the AP/APCL series over the apsm. In reference to them being over/underrated, whether the 1500 does 1100 or 1500 watts the difference isn't drastic enough to notice. Plenty of power for a pair of SA's.
