Well I suggest that if you are going into competition, street A, you bettery get a stronger amp than 3kw. A 3k watt amp in a dbdrag competition will only get you sent home!!! I tell you that!!! I recommend you look for a Z1a, stetsom 7kd, atomic 5k or 7k, or an American base 5kw or 7kw. Anything less than that for Dbdrag street A is uncivilized!//content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif And a wast of TIME!!!!!!!//content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif//content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif//content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif12V system and battery HX300, PC 3000 or NSB 90 for street A aplication ...
