Allrighty I got to a 155.2 with 2 amps strapped at 1.4 I just ordered another level 5 18 and this time she will have 6 spiders and I will strap them .7 on 2 amps at first to see what kind of gain I see then it will be time to run4 amps on it this should be interesting.oh and before anybody says that is to low of an ohm load i will let you all in on a secret those powerbass 5000s were burped at .175 however in my opinion i do not like to go lower than .25 but they took the .175 like a champ.
