best way to wire amp/sub

[Formula Z]

ok i have 1 rockford fosgate 1000 watt P3 12" DVC 4ohm sub. i have a 2 channel pioneer 760 watt amp and the specs are: Peak Music Power - 760-Watts 4 Ohm 125 Watts x 2 Output Power 4 Ohm Bridged 380 Watts x 1 Output Power 2 Ohm 190 Watts x 2 Output Power 1 Watt into 4 Ohms 75 dBA Signal to Noise right now i have the amp bridged and the sub wired in parrallel i believe.this thing pulls a ton of power, i can even see my gauge dip when it hits. my power cable is not big enough i know and am replacing that this week. id like a capacitor but dont have the cash right now. i listen to everything and want it to sound good no matter what im playing and how loud its playing. to much to ask??? oh yeah the sub is mounted in a sealed box with a foot of air space which i think is correct for this sub. thanks

im confused so what is the bottom line question?

You did not mention what gauge power wire you are using I would run seperate power from the battry 10 gauge for the 750 amp and 8 gauge for the 1000 amp. also you definately need a cap on each line. Then the final thing you need to up your altenator to at least a 140 watt. stock on a v8 is 105 watt if I remember correctly. If you can't give the amp the power it need it don't matter how powerful the amp is it won't deliver.

should run 4 gauge wire for 1000 watts... I would recommend a cap, I bought mine off of www.sonicelectronix.com for $50! But what is your bottom line question, what way to wire your subs for best quality? Is your amp 1ohm stable or 2 ohm?

I can't remember cause I read so long ago, but reading over on Ls1tech in the car stereo forum, they have shown that there is no need for a capacitor. They do something called the "Big 3" mod. I believe it involves upgrading all power wires, but I'm not positive. Go look in that section. If I get some free time later I will research it some again.

Cap

a cap is ALWAYS a good idea unless you want to run a seperate battery for the system. It will reduce the wear and tear on your alt. It is a good idea to up your alt to if you can. Most of the cheaper caps dont work real well as compared to like a Rockford Digital 10. But that is correct a good amp is worthless if it dont have the proper power going to it.

I agree, cap's really are a good investment act like a band aid for your system and will protect your car. Here is a good site for wiring diagrams just plug in what you got and what you want and it will show you how to wire it.

thanks guys. main ? was is my wiring correct? i do need bigger power wire, so mike i may have to hook up with you and pick that up if possible and thanks. my power wire is only 8gauge i believe, but i was only pushing a DEI 300 watt amp before with no problems. the amp is only 2 ohm stable. thanks for the links and advice. a new bigger alternator and battery is one of the next things the car will be getting, along with a new power antenna.

just wanted to say thanks to mike k (mikek18) for hooking me up with a new power wire. havent gotten it installed yet (huge wire compared to what i had so running it from the front to the rear is a little more work) but it should be done this week along with getting my cutouts welded up.

thanks mike, i owe you

I Just ran 4awg for my system, It was pretty easy ran it along the passanger side with the factory wiring, I took a heat knife and shaved away a little of the foam in the rear pillar so it would fit properly. make a clean looking install when ziptied to the factory wiring.

no problem man.
