[Answers to Roof Cracks]

Gonna weld it and let Line-X bed line it as long as its allowed in Meca mod 5.

[MECA Rules ?]

Are there any rules dealing with bed liner on the roof of a vehicle?

Class is mod 5.

[Answers to Roof Cracks]

Well my roof finally gave up on me. I have three cracks ranging from 1" to 6". Only reason I bothered to look is because my score at a recent show was a full dB lower than normal and I demoed with the door open a few times. During my park and pound run my roof was looking really weak.

What have you guys used to fix the cracks in the roof? Roof sealant didn't hold up to well last time. Probably gonna see if one of my grandads friends can get the welder ahold of it.

[New box design, How's it look? ***changes made***]

i'm just saying that you can't always trust what you hear haha but yeah, bigger box, tune higher.

I trust myself and especially trust what Alpine and Ray say. There's more than a handful who have tested the 45's. I wouldn't use them.

[how much power can an xl coil handle?]

Mine got to smelling off a AQ 2200d each after 2 or 3 songs. Never failed but always got warm/smelly after a few songs. I'd say 3000 would be the limit I'd want to throw to them.

[what causes pico fuse failure???]

Hooking up your rcas to your amp before the ground wire. Always unhook rcas first and hook them back up last.

[Help me Sketch This Design (2 Havoc 12's)]

And to piggy back off n8, the more room you have between the end of the port and back wall the better. Both for spl and quality of sound, in my experience.

[Help me Sketch This Design (2 Havoc 12's)]

Depth of box is 28

Depth of port is 30

The port would have to bend. Typo?

I'm on on mobile and the calc is small so I may have misread.

[Sheathing to house 4 runs of 18 gauge]

I'd get some wire loom. Home depot, Lowes, etc will have it.

Can you provide an exact pic of what your talking about?

Wire loom?

[4 15" Fi SSD build** CUSTOM* **TeamHirshAudio**]

I have two all threads front to back and 1 dowel side to port. Who chose 1" dowels? Was it a money thing/customer thing? On those long side to side pieces I would have used all thread, and I'd never use smaller than 1.5" dowels, unless the distance is extremely short.

[4 15" Fi SSD build** CUSTOM* **TeamHirshAudio**]

I have 3 braces in my entire box. That's for 4 N2'S and two 3500.1's and is holding up fine at 155 dB. I'd rather add layers of wood than start throwing in too many braces. You shouldn't need but 2, maybe 3 braces in that box(2 across, 1 top to bottom) if the box is designed/built right.

Looks like the customer wanted a lot of bracing anyways. Not sure why.

[Hot weather]

Better than 150 in an attic. I'm with Hugh, tough it out. Put a floor fan in their if it's that bad.

[alpine MRP-M1000]

Those amps get very hot when clipped.

[How to secure a wall to a car]

Use the available bolts to bolt the floor/base down and use angled brackets in a few areas. Use plenty of screws to secure the box to the floor, and maybe secure the base of your box to the false floor with bolts and screws. Id also try and get a brace or something to secure the box to the rear deck for added support.

[Big Enough for 2 18's?]

I say go for it. Looks good.

[Will my amp stay cool enough behind wall?]

It'll get warm and even get hot on the extreme heat of the summer, but shouldn't get too hot as to damage the amp or go into protect.

During all other seasons I doubt it'll get real warm depending on where you live and the weather.

[box btl n2 15]

If you got the time, money and want to, I'd build the box around 4.25 cubes. Try it out, play with some different ports, decrease the size, play with port orientation, etc and see what you like the best. That's what I did with my n2 while I waited on the others to come in.

But if your like others and want to build the box and not touch it again try 3.5 cubes, 55-60 sq in of port and a tuning of 32 hz.

[box btl n2 15]

That's all in your box. Mine do well from 30-48 hz. Starts to roll off pretty good above 55 with it tuned at 34 hz.

I'd tune it to 32-35 hz.

[box btl n2 15]

Does that amp do rated and at what voltage? What's your electrical like?

If your getting 3000 wrms out of the amp I'd go with 3.5-4 cubes with 55-75 sq in of port.

[Little problem here]

I would have lost it, if I lost out on 10 hrs pay. Some people just don't give a shit about others and he definitely is one of those people.

Kudos for having the patience to put up with him for this long.
