ok i have just decided that the racecar can wait for another year while i get the truck thats gonna pull it ready and get a system in it and the new bike i want is gettting to be out of the question and all the money i get is goin into the truck which isnt alot because i dont really have a job right now but ya just give me suggestions on this and ill go from there

 

r these good subs?

i have like no room back there cause i wanna keep the back for storage. it is not an extended cab. and i dont think i want an amp for the sub i have. but idk if they r really any good i have two of them, but i only have one in a truck box behind the passenger seat.i would really like to come up wit a design for under the seats, i will take measurements tomorrow under them. should i take some pics of all this so we can get an idea. and i would like to spend about 150- maybe 200 if i go any higher i will have to wait even longer

 

where do i get the 6.5s

 

do u know what the model was and how much it was cause i kinda thought memphis was kinda exspensive

 

which one of those would be good and i think i will start with two for now

should i build the enclosures about .75 each tuned to about 35hz
each with a 2in port about 7.5in long
