I have 3 amps to choose from and 3 sets of speakers to choose from, so i need someone with knowledge to give me advice (I'm not really sure about the standards used to pick audio stuff).

The amps:
Cadence z100 ultradrive
Blade g5 grenade (no idea on the power output, but it's a big amp)
Lightning audio B2.250.1
Speakers:
1X Kicker 12" (can get the model number if needed)
my kicker speaker looks like this one:

2X Sony Explode XS-L1236
1X 15" Interfire IFS-15D4

I have 1 speaker box for my 99 mustang that holds 2 12's, fires up, sealed, and has 1.32 cuft per speaker. I'd be willing to build a different box if needed.

Anyone have a suggestion? I know there is way better stuff out there, but this is what's sitting in my house so its what I got. I'd like to know the best setup (for me) and the second best setup (for my gf, haha).

 

I cant give you advise as most of that stuff Ive never heard of. I think the best thing you have there is the Kicker12 the amps I think are very low end and will probably blow out prematurely. My brother learned this the hard way. He had a graveyard of amps in the garage.
