Avalanche help

[toolshed]

Anyone put a spl system in the bed of an avalanche? What tips and suggestions could you give? I'm thinking 15s in a 4th order

First thing is to make sure you bed panels don't leak. i had leaks so i bought a new cover, the rest is up to what you want to achieve.

i did a 149.7 in my avalanche on 2 18's. check out mine and moredbs builds. i learned a lot from him and I'm sure you could get some things from me. my bed leaks a lil thats why i fiberglassed inside and out my box and bed lined it to protect it.
