Oh ok I wonder if Tony D has heard of this?

1.8 volts might not be enough to make the amp stages saturate. It's like having an 8v output head unit but only turning it up a little bit. Apparently the amp needs a higher input level than most. Get a preamp eq or better head unit to jack the signal up.

We are beating a dead horse. This has got to be the longest vs thread ever. Anyone else with a legit vs question gets smacked. Just sayn.

Cool! I just looked at the specs. It says the woofer is crossed over at 2khz and the tweeter at 4khz. Is this gap noticeable in the mid range as it looks like it would be missing? Everyone seems to think these sound good so it must not be an issue. This would be perfect for me to take to work if it were a little more rugged.

It's fun to buy another amp and install it. Maybe get another identical amp and strap them together?

I am lost. I was trying to figure this out yesterday. Where do I sign up for supporting member?

I want these for my doors!

What frequency are you tuning to?

It depends on how peaky the box is too I guess. A big ported box will have a lot of peak and a smaller ported box will tend to be flatter.

Tuned to35hz it will play 35 real good and everyhing else will sund about half as loud. If you were to listen to a song that has bass around 50hz, you would be saying " where did the bass go?". Sure it wil still play 50 but it wont bang like 35.

If you want it to bang the high bass as well as the low bass then that would be hard to do with a port. The SQ can be lost real quick with a port that can peak as much as 5db. It sounds like what you want is a sealed box for a nice flat response and gradual roll off. It wont be as loud as ported so it will need alot of power. Everything is a trade off. I am in the same boat with my HDS315s port tuned to 34hz. It just dosent bang the high bass like my old sealed box but it really smashes the lows. I am planning to add four 10s for some upper bass kick and have been told repeatedly that this is wrong but i have done it in the past with good success.

For the same amount of power, cone area is king.

That's awesome! Big wire that's still flexible.This is the first 8/0 I have ever seen. Usually when it gets this big, it is measured in MCM. Maybe you could do a demo putting some lugs on it? Thanks man!

That's the biggest little sub I ever saw! lol

If its tig welded then spatter won't be too bad. Mig / stick will throw more sparks and will definitely need a second person watching for fire.

Get well soon and speedy recovery!

The door speakers need the whole volume of the door to work properly. By using the baffles you effectively prevent the speaker from playing any low notes including some of the lower mid range / upper bass. Remove them or cut the back out and you will notice a big difference.

Sometimes when I post from my surface tablet and hit the POST button, I see something at the top of the screen and it looks like nothing happened. I have mistakenly hit POST again only to find out that it worked the first time and now is a double post. Like the page does not refresh when I hit the button. Hitting the LIKE button is the same way.

3 amps might have more head room than a single amp due to the total available power supply sections in the amps would probably be more than a single big amp. You might get more responses by posting this in the general amp section.

I wonder if there are any other amps that run this board?

Some guys bang them until they can smell them. I have smelled my HDC315s a few times. I have learned how to keep them in the "safe zone" so maybe they won't die any time soon. Can't wait to see your build! I would love to do a wall. Maybe some day.

Are the T/S parameters the same?

You rock Steve! We love your videos! What is the name of the song in that vid?

Nice work!! My 4/0 upgrade will include a set of these!
