i have recently upgraded all the door speakers and now have my highs and mids covered with MB quarts Components it the front doors and 6.5 kappas in the rear doors. Now i am moving on to the sub woofer. the stock sub is an 8 inch and theres not much for options to put in the stock location. (too shallow) so i have decided to put a sub in the back cargo area. i am going with 10 inch too keep the size down. im trying to create a hifi sound system more than a block shaker. i am only going to put in one 10 ich woofer to compliment the components. my question is which sub set up should i go with. a 10 w3 with a jl 250/1 amp or a 10w7 with a jl 500/1 amp? obviously everyone will say the w7 because its more powerfull and alot more expensive! Is it worth it? also what should i do for enclosures on either sub? sealed? ported? i have a 10 in bazooka tube that i was going to use if possible. will the w7 sound ok in it? would i be better off with a sealed box? i would like to keep my cargo area as empty as possible thats why i like the bazooka tube. shine some light on the subject for me.
