Sorry haemphyst, I was speaking about the power wire as if he didn't have it already. Yes you can never have too much, but if he hasn't already bought it, he should just get 4 gauge and save the extra money for better equipment.
As for the 300 amp fuse, I know it will save the car, but I always aim for the amplifiers fuses, and nothing more. I didn't mean for it to say that it wouldn't protect anything at all (the amplifiers were the main thing on my mind when I wrote that).

The way you are hooking up the subs are fine. To my knowledge the RFP4212 is dual 2ohm subs. So your basically running 2ohm stereo which is more than sufficient.

Yes I would run 4 guage back to the amp.

I've done alot of systems on a budget. If you like the tweeters keep them. Its your car and your taste of music. If you like the crisp highs then its your discretion to keep or remove the tweeters.

As far as the Alpines, I would either add a small amp w/crossover or just use a bass blocker. You should be able to find them at your local stereo shop.

I would amplify those alpines, something like this http://www.cardomain.com/item/LITLA13002 or http://www.cardomain.com/item/JENPS475.  Something like that.  If your not going to put anything but deck power to them, your not doing them justice.

Noooo.....   These are your subs http://www.cardomain.com/sku/ROCRFP4212.  Dual 4 ohm voice coils.

IMO "bassblockers" are a waste of money if you are using the deck power, you have little to gain. http://www.cardomain.com/shoplist~b~Lightning+Audio~t~Passive+Crossover+Components So like 12-15 $  A waste of money for little to no audible change.  If you havd 3.5's or 4x6's 4's i may change my mind.   Just get a amplifier if you want better sound.

Okay so their dual 4ohm. Wire the subs in series to create an 8ohm load on each sub, then parallel the two subs together for a single 4ohm load. That way you get a 4ohm mono load

And I disagree and agree with the whole bass blocker complex. If you have the money get an amp w/ builtin crossover for the Alpines. However, if you are on a srict budget the bass blockers will work. Most bass blockers crossover at 150hz only allowing notes 150hz and above to be heard from the Alpines. Basically midbass and treble.

Agreed. An amp with an electronic crossover would be best. Bass blockers are the cheap solution. Just know that SOME SORT of crossover should be put on those speakers if you like to push those drivers.
