honda crx spl recommendations

hi thanks for reading.

i plan on building my 1988 honda crx for competing in db drags. from reading on here i think ill go with 2 12" kicker L7's. i also want to use 2 hifonics brutus amps, probably the 1200 watt rms ones. i have competed before in 2000 and 2001 where my best was a 151db with two audiobahn 1505's subs and one audiobahn 2300hc amp. this was on the old termlab(anyone know what that number would be now). anyway heres the questions. what size of box should i biuld i think my crx peak frequency is about 45hz (if anyone can second this). should i build them in a common chamber? ported lower or higher?   sholud i upgrade the electrical which is now all stock. if i put more than one battery does that put me out of the street categories. i used two use 3 batteries back then, but that was when they only had street, super street and extreme categories(i was in super street 1-2 no wall). thanks for your time. nino. 

thanks jeff. ive got some more questions.

does it matter which way i face everything. i was thinking speakers up and ports to the rear. what do think. also would i be in danger of damaging my subs runnning them at around 1200 rms for comp time. do you have any other amp recommendations. should i play tones only or sweeps. im hoping to hit around 148 on a termlab does that sound within reach. where can i get some aero ports. thanks for all help.

thanks. i started placing orders already.

jeff if you say that "with the power you have I recommend the l5's" should i go with more power such as the hifonics brutus 1600rms. does anyone have any other recommendations over the hifonics. what do you think about sound deadening. would it help any in my situation. how abouy any battery advice.

Digital Designs DDZ1 is one mother of an amp, same with the big MTX amps, something strappable might be a good idea as well. Give those suckers some power.

i live in las vegas new mexico. i plan on competing in pueblo co on may 6th(maybe) and in raton nm june 6(sure thing) and in alb nm, not sureof the date on that one. there isnt very much in this area without traveling far.  i already ordered the l7's but i still have not ordered the amps. are the mtx and dd in the same price range as the hifonics. im looking to get my amps online at the usual places.
