I dont think you can strap the 1500 or the 2500. http://www.rockfordfosgate.com/products/product_details.aspx?itemid=117366

But no adjustable ssf .

If you strap 2 amps together they act as one. A master and a slave all the adjustments would be made by the master. This eliminates having to set up two amps.

It there a way to determine your exact box tuning ?

im NOT talking about the OP. nevermind. Your talking on how to set it properly.

With the amp he is using if you tun the ssf on it goes to 28hz no adjustment.

What ohms are you going to be running the speakers?

Devcon epoxy has worked good for me.

Then a ssf set at 28 hz is to low. It should only be a few hertz below 33.

Whats your box tuned to?

so subwoofer build error and amp build error is out of the question? companies make mistakes FI basically blames large korean amps sending microwaved signals but OP has a quality sundown..... if all but 1 had a coating then there's still no way for them to touch each other and short out OP even noticed something funny about the sub before the fire It also said there were problems with the sundown saz-3000d.

What was the ohm load the subs were wired for?

Lets hear from some people that have had good servce from Fi. I did but its was back in 2010.

That was nice!

Do you have front and rear speakers?

Good luck with your build.

I would still consider the SSA gcon 15 750wrms x 4. I ran 1 and hit 140db. With 4 on 3500k eventually I would think 150db + . They say they are sq but they can get loud. The x would be a good choice also.

I still think your best option is four 15" subs at the power you will get.

How much do you want to spend and power them with how many watts rms?

Then buy the psi subs if you what fancy looking!

Look at the previous post. You are correct chanel 1&2 do left and right front speakers chanels 3&4 do the left and right rear speakers.

Your head unit manual should have those. http://www.hifisoundconnection.com/Shop/Control/fp/SFV/30046/view_page/Amplifier_Types_2-Channel_4-Channel_Mono_Multi-Channel
