Wow, someone comes on here seeking knowledge, and most of you mock him and his equipment. Sad part is, none of you will admit you started with a Lanzar amp and thought it was the coolest thing in the world.
dlow265, as far as your equipment goes, it's very low end. It's difficult to say if it would truly hit hard because low end equipment like that exaggerates it's numbers. If the subs you have can even handle 300 watts a piece, then yes it might rumble your car a bit. It may not have that clean punch, but it will make a rumble like noise. Running your Sony amps at full tilt, meaning the gain all the way up, will put a lot of tax on an already low budget amp. It could potentially lead to it's death.
If you already bought the equipment, I'd say just test it out. Try running the subs with only half gain. Like I saw someone recommend, get more familiar with the forums to learn more, then you might get the itch to upgrade and will be better informed.
If you need any advice, feel free to PM me.
