[600 watt rms extra on stock alternator and stock battery.]

yep hes right^ theres no need for 0 gauge, 4 gauge is what i would do instead plus you can save a couple bucks and buy you a nice set of components for the front

[powerbass xa3000d @ .7ohms?]

but im going to use 2 15's but what coils do j need

[powerbass xa3000d @ .7ohms?]

alright thanks and if i do wire it at .7 what coil configurations does the 2 15's have to be?

[powerbass xa3000d @ .7ohms?]

right now im running it at 1.34 ohms with 3 12's and going to 15's but can the amp handle .7ohms?

just in the future by a little xs power batt just in case if you want your voltage to stay at 14v+

[what alts/ bateries would i need to support 4,000 rms]

im just going to get a 350a singer alt and a d3400 up front and a d3100 in the back

[what alts/ bateries would i need to support 4,000 rms]

thanks CJ i might do that

[what alts/ bateries would i need to support 4,000 rms]

oh alright and what if i get 2 xs power 14v batts? and charge at around 16 would it drop the same?

[what alts/ bateries would i need to support 4,000 rms]

right now i only have the big 3 and 2 yellotop optima and stock alt and my voltage sucks, drops to 11.9. yea im looking into the mechman 270 and 2 d3100s and how well this keep my volrage at?

[what alts/ bateries would i need to support 4,000 rms]

and thats it, so a 220-270 amp alt and a d3100 up front and my voltage will be good?

[what alts/ bateries would i need to support 4,000 rms]

i have a powerbass xa3000d and a rockford t600-4 in my 2003 chevy suburban. my question is how many batteries and alts do i need? and how many amps does the alt have to be?

[Focal Access 165a1 comp set in Houston]

where are you located?

[Box for JL 13W7]

ithink 3 cubic ft for 1000 w is perfect and portwise about 12-13 per cube tuned to 31hz

[Box for JL 13W7]

i think 4.5 cubic ft is too big for that much power i would do 2-3 cubic ft box tuned to 30-35hz and more port area instead of 9 per cube do like 12

[subs are a little smelly]

been there those subs never stopped smelling till they died and they want weird boxes to get loud they can barley take 1000 watt so be careful

so should i change the subs to some sundown sa-12's ? or any suggestions on some subs that handle anywhere from 1,000 to 1,500 watts rms?

[subs are a little smelly]

are the subs brand new? some subs smell for a while when they are new.

the subs are not brand new there about a year old.

[subs are a little smelly]

well i have a upgraded alt from a chevy 3500 in a suburban with 2 optima yellowtop with 2 0 gauge runs to the back with the big 3 lowest ive dropped is 12.7-12.9

[subs are a little smelly]

probably the lowest ive played is 28hz . i have a sony deck and a clarion eq if anybodys wants to know

[subs are a little smelly]

i have 3 pioneer premier pro 12's which are 1,000 watts rms and powering them is a powerbass xa3000d @1.34ohms. the gain on the amp is at 1/4 up and the bass boost is all the way down and after a song or 2 the subs start to smell but not too bad. is it that my box is too big? its about 5 cubes before sub dis. tuned to around 30-32 hz or should i just change the subs?
