I just purchased two 12w3v2 dual 6 ohms with a jl 300-2 amp now i have heard the way the suckers sound and they hit but my system really sucks i get distorting about 1/2 way throught the volume and the dealer that installed them allready re-configured them once they had them in serial giving 12 ohms wich was even worse but here is the deal they are now wired in parallel at 1.5 ohms. Should i go with the 4 ohms and does any body know they best configuration.
