Thread: 15" sub

I have 2 s12l7 kickers in my car (them being square they have the same surface area as a round 15 inch sub) They rattle my car apart. Anyway id say a box volume of at least 2.5 cubic feet PER SUB enclosed. My l7's are in a very small bandpass box (1.32 cubic feet) and it sux. If you are looking for sound quality and just not all out db go with a enclosed if your looking for all out db go with ported or bandpass box tuned for your subs. I think the enclosed boxes are a richer sound. I also hate the sound of all the air rushing out of ported/bandpass boxes. Thats my view tho some might disagree with me. As for amps you get what you pay for if u buy a cheap amp it will be a pile of $h!t. I got a cheap amp for my subs and it was rated at 1700rms@2ohm mono class D amp. So I figured it was pushing about 90% of its rated rms watts which is 1530 rms. My subs are 750rms each and I know they are not hitting anywhere near as hard as they can. The more money u have the better sounding system you will have.
