Guys looking to get some help on my future upgrade. I currently have 4 12 lanzar opti. I have a 2002 impala. Alternator 240 amps kinetik battery 1400. For the amp I just recently ordered a DC 5k and waiting on the arrival still. So I'm debating I want 2 18. Will be in trunk and box will be the whole trunk. So it's either 2 18 DC level xl or 2 dd3518. If any other brand let me know as well with price. I want my budget to be around 1100 for both. I will mostly likely by one then the other. I want to run them at 1 ohm so wat vc should I get?
