PA a3000db help**

okay, i went ot my local shop to get some distro blocks and all. i got an inline fuse holder with 300a fuse because they didnt have anything else, and i got a distro block then i got a 100a fuse until they can get some bigger ones, i got some terminals, and some 4 ga wire(6-7 feet) for right around 50$, now all i need is some 1/0 wire and im set

prob(kinda) i got the amp installed, but im still using my 4ga right now until i get the 1/0, so i have my old fuse holder with an 80 amp maxi fuse, i take out my viper and finish that up run 4ga to amp finish wires and such, so i get my dmm and set the gain (since i want 1800 watts @1ohm 1800x1 then square root right, so i get 42.4 or something i think) then i check it, but i think 1 thing, does that 4 ga let enough power go through so that im not turning the gain up too high to get the right number? would it be clipping? ( i usuall dont turn it up past 26 even when showing people, so i set it there, i will set it at 30 tomorrow prolly

now another question, i dont think an amp has much to do with the way your setup sound, but now i have more higher bass and less lower bass, i dont really under stand this, and it also dosent sound as a couple answers

1: i moved the box foward like 2 inches

2: i undid the ground on the batt so i lost everything on my cd player, but i think i got it all back except for the high frequencies on the eq

3:the knobs on the amp arnt set right(i dont think so, the ssf is right in the middle between 40 and 15 hz so around 27.5 or so and box is tuned to 32hz

4: anything else??

can anyone answer these for me,

it was really dark and i couldnt see much, so i dont know if everything is set right

but i will get up tomorrow and check it out some, because its a little louder but i need some help and some light to finish everything, and how much will the 1/0 help, im confused a little because it dosent seem much louder, i dont think its getting enough power or something, any help

wit that amp youll probably need 4 awg ground, 8 awg seems to small. if it seems quieter maybe your getting voltage drops? use a dmm and check the DC volts on the power and ground wire. you should be getting around 12.0v (wit car off) to around 13.8-14.4v (wit car on).

Also re check ur xovers. On ur amp or head unit.

Also try moving your box to where it used to be and see if its still quiet. Sometimes moving ur box can effect the sound.

Your ground should always be the same gauge as your power wire.

You more than likely wont hear a major difference in the sound between the 1300 or so the viper put out, and the 1800 from the PA. Its too bad Jmac retired, he had a very scientific explanation of it all.........
