i just bought more speakers i got 2 alphasonik 600j 12's the owner of Car Audio Invasions here in Picayune Ms says I am hitting 165db and the thing is i need a new alternator cus its not strong enough so i hit 165db with a power suply of 10.5V to the sub amp
he says i should upgrade my alt and then inter in to the usac in Baton Rouge La in a couple months.

He is thinking about hosting a comp here but the next closes one to me he said is his truck 157Db

I have an planet audio 1400d (1250w @2ohm) class d mono block amp
the 2 alphasonik 12's rated at 700w rms
a ported box total 4.33 cubic ft air space
a kenwood head unit with frunt rear and sub pre amp outputs.
an american pro 1.2 frad didital cap

american pro 600w 2 chanel amp for highs(no rear door speakers yet)
2 alphasonik tweets
2 pionerre 6.5 3way in frunt doors no dash speakers yet
(plan on going with all alphasonik speakers just wating for them to come in)

(use to have all Memphis aucio but i blue the 2 m3 12's i had)

plan on adding a 3way cross over and a 9 band eq with sub controll

anyone this this is an ok system?

 

first off, I don't think there is a chance in hell that you are hitting 165 db, no offense, but I was running an APX 18 in a 10.5 cu ft(before displacement) ABC box tuned to 37 with 3300 watts through it and I was only hitting 155. and that was with 0 gaugee and a 200 ap alternator.

 

Yea dont wanna sound like a jerkoff but I doubt it too. 2 L7's barely hit 165 and alphasoniks are THAT great.

 

well it just cracked my windshield

 

lol I've done that too. Its honestly not that tough to do that

PICS! I <3 stereo pics

165? one of those see it to believe it, my last system was a lot more than that and I only hit 155.3 in the back of neon

 

lol, im sorry man, but if you dont even know what your taking about, you DEFINATLY arent hitting 165Dbs. even on the AC, i highly HIGHLY doubt your hitting even close to that. it takes alot of work and knowledge to get that high. sounds like someones just pulling your string for a sale.

 

lol i would doubt a 165 at the port! and 700 watt sub......................... no sorry man [&:] Go slap that guy at the shop in the face.
