I am aware that the stock speakers in the 1ls are 4.5" speakers, but has anyone modified their boxes to sit 6.5" speakers all around (front and rear)?

I know 6.5" speakers can push much more air so that's why I was wondering if anyone has done this upgrade.

Discuss!

heres a tutorial for a 5.25 speaker, Id imagine the process would be the same just harder to do for a bigger speaker...

just cut a bigger hole or make a new baffle.

Most likely easier to make a new baffle for the speakers if you plan on running 6.5" speakers. I modified mine to 5.25" with a dremel tool, took awhile and was a slow process, but the speakers fit but you will have to reinforce the one edge b/c it WILL crack once you screw them in.

It's alot easier just to make a baffle out of MDF. Modifying those stock speaker boxes aren't worth the time.

Yes it is a very easy job to open up stock speaker mounts I have done 1st gen LS and 2nd gen LS.Plus the rears too.

Lexkost, is there any way you can send me high res pictures of the 1ls ones you did front and rear?

Lexkost

I don't remember where they are , the 1st gen belong to persian451 you could try a search , I don't keep many pics on my computer and dump them after I use them , sorry...But if you are a SoCal guy I could help you out at my garage ( shop ) .

Unfortunately I'm on the other coastline, lol.

I'll try a search.

For the 1LS ones, did you simply just dremel the enclosure into a bigger hole without tampering with the backside?

How did you mount the speaker into the hole after that, just screw it in?

Yeah I just put 6.5 JL Evolution components in my 1ls. The key is spacing. After cutting the hole I bored out a .5" spacer, and mounted the speaker to the factory housing. The key is to not screw the back part of the housing back on. All in all it took me about 3 hours, then again I'm an installer lol. But good luck and take your time!!
