What amp to use

What amp should I use for my JL audio stealth box? Rockford fosgate punch P400x2? Or PG tantrum 400.4? Also what gauge wire kit should I use? Also I have the JBL audio factory in the truck if that matters. Any help you'll be awesome. THANKS!

 

I used the jl slash 600v3, I have a pic somewhere here under my user name

 

What do those cost? The guy at the shop said to use the JX 250/1. But I don't wanna buy a third amp if one of the two I have would work.

 

Neither of your amps will work unless you rewire the box so it has 2 channels instead of the single channel they come with. If you do that you could use your PG which is considerably better than the jl250/1. Ideally you need a single channel or mono amp to deliver 600w as each sub is 300w, you can go 75%-150% of this value. You should be looking for a 2 ohm amp to deliver from 450w-900w, that being said the jl250/1 is too small, however the jl500/1 would be a better match

 

Yeah I was looking at that amp. I saw someone with the stealth box with the 500/1 amp. Also should I have 4 or 8 gauge wire and what's the difference with gauges? I would like to know more about these things.
