What size speakers for sub box?

I am looking to put subs in my truck and don’t know what I’m looking for what size speakers should I use and a reasonable price.

 

It depends how much of a heavy hitter you are .
I have one 10 on the passenger side and it sounds really good .
Mr marv makes good stuff to put your own sub . JL Audio makes some nice stuff also
I have a 4 door
Extended cab if you don’t mind using one side on the floor a nice regular box sealed with a good sub works fine
But again if you want serious bass then sky is the limit

 

I’m just looking for something to put behind my seat in the back maybe like 2 10” or 12” idk what would be better if you can fit 12’s?

 

If you go with JL audio they actually make a self powered 8 that will fit in the cubby.Or you can get a stealth box from them. If you do the stealth box you need an amp. The first one you don’t .The other way is to get a pre made or custom box and then put your own sub and amp . Anther option is to look into oem audio . They have a speaker system for our trucks that is plug and play

 

I've got an 8" underseat Powered Sub that kicks pretty good a$$. Spliced from my rear speakers, behind the HU.

Pretty impressed how much bass I got from so little space.

 

Which one did you get?

 

I have a single 12" behind the seat of my DCSB. If I had to do it all over I would have went with a single 10".

 

10 ‘s are nice because they produce tighter bass than a 12 sometimes. My last truck extended cab, I had two 10’s with a Alpine amp set up at 2 ohms about 600 watts and it was pretty impressive. Polk separates up front and 6 in coax in rear . Probably one of the cleanest systems I’ve owned in a long time . Not super loud but really clean and tight.
