Upgrading to a powerful system (1500+ watts)

I think I'm just gunna go with 2 Fi SSD12's...

5 cubes @ 33 Hz

I read somewhere Fi recommends 12-16 sq. inches of port per cube... so 60-80 sq. inches of port area. I designed a single chamber box with a slot port on the left side 12.5" tall, 5.5" wide, and 25" long (68.75 sq. inches of port). It may need to be longer though. The box had a double thick baffle and all the rest of the walls were just 1 layer. It came to 5.366 cubes after sub and port displacement... but I figure I might have to make that port longer... plus brace it with like 4x4's.

 

68.75 sq. inches of port sound good?

Azn can you check the length of a port that's 12.5" tall, 5.5" wide... and the box is 5 cubes tuned to 33 Hz.

 

Well I listed my 2 subs and 2 amps on facebook for $450 with the box. I also said I'd build a custom box and/or install them for a low additional cost. Hopefully someone at my school will jump on it.

 

Well I only had the listing up for like 2 hours and I've already got someone wanting the subs and amps saying $450 was a great deal... score. Now I'll just get the kid to have me install it for another $50-100.

 

Alright now I got another kid who just wants the subs. I'm liking this facebook marketplace thing...

 

What do you guys think I should list my 2 amps and 2 subs for? Circuit City charges $300 per amp and $150 per sub... but I think they used to have a 2 sub for $150 deal. I'm only listing them at my high school. The amps and subs are in excellent condition... no scratches or dents. I raised the listing from $450 to $550... just curious what happens.

 

Okay so the kid who wanted to buy it for $450 was like what the hell when I raised the price to $550 lol. He asked if I could sell it to him for $450 because that's what he saw first. I said sorry $550 is as low as I can go... and he said alright it's still a good deal anyway. He said as soon as he has the money he'll let me know. The box is an additional $50.


The amp I want is $450, the 2 subs together are $378... so $828... then I need 1/0 gauge, a second battery, relays for the battery, and to build a box. I was thinking Knukonceptz Kolossus Kable (5145 strands) and one of the SPL guys recommended an Odyssey 1500 or 1700 battery.

 

Do you know how they compare in price to say a yellowtop?

 

Well I still haven't decided if I want to sell my equipment yet. I have 3 people interested. The price right now is $550 for the 2 subs, 2 amps, and I might charge a little bit more for the box.

I can't decide what to do...

If I got 2 Fi SSD12's, a Sundown Audio SAZ-1500D, an Optima Yellowtop battery, 1/0 gauge Knukonceptz Kolossus Kable, battery relays, and the supplies for the box, I'm looking at like $1,200-$1,300.

Do you guys have any other system ideas that would be louder than my 2 CVR12's but more cost effective?
