What up caraudio.com? Right now I have one Dual 2 ohm12 in. Comp Vr in a small ported box inside a Ford Explorer. I have this running off a Power Acoustik LT980/2 bridged. This sounds pretty decent but I want more, my question is would 2 Comp VRs in a ported box give me better results or should I upgrade to one 15 in a ported box? Whatever I get will be running off the same amp I am already using. Oh yeah the amp is rated at 560 watts @ 4 ohms bridged and 220Wx2 at 4 ohms. Appreciate the help.
