Recommended Posts

Posted

Hey guys, once again im stuck on making a dicision on my truck during the build. i did some detailed measurments and turns out i have 6.5cuft to work with after displacments. now i was going to run the FiBTL15'' but seeing how i have 6.5cuft, would it be a good idea to run the 18????

which one would give me better bass and loudness. i dont care about SQ mostly SPL.....

would it be better to run the 15'' at 5cuft, or to run the 18'' at 6.5cuft.

thanks guys for the advice

If your open to other brands a custom Nightshade 18'' would work perfect in 4.5 cubes. If your stuck on FI I would definitely get 15'' as you probably won't have enough room for an 18 after port displacement.

i havent had much experiance with nightshade. ill have a solid 6cuft when everything is said and done with everything. I can go ahead and say this, "i only do 1 18 or 1 15'' behind my seat because i dont put a woofer behind my Girlfriend (soon be be wife) seat. so another woofer it out of question.
