So I currently have one Kicker 15 inch 250 rms 4 ohm sub in my car powered by a Jensen JPA460 amplifier. I want to add a second subwoofer to my system a 12 inch 150 watt rms 4 ohm kicker. (i know kicker isnt the best but its what i can afford, im 16 years old). I'm planing on building a custom enclosure to hold both the subs (in separate chambers) that will look like this It will have a total of about 10.24 cu. ft. (5.12 on each side). My amp has tuning options for the xover lpf and hpf and i would limit each sub to prevent frequency crossover. Later on, when I have more money, i will be replacing my pioneer 3 way speakers with a component system, 2 6.5 in midbass, 2 8 in midbass, 2 2 in tweeters and 2 4 in tweeters. Soooo what do you guys think? should i or shouldnt i do this?
