rear speakers in a double cab

so after i got my tacoma i changed the head unit. then i wanted to change the front speakers, put pioneer tsd1602r 6.5's in. Now the rear speakers sound like garbage when i turn up the volume. I called crutchfield to inquire about speakers for the rear and according to their info they are saying there may not be enough clearance for 6.5's back there. Will a 6.5 fit back there or do i have to modify the door? also, will it be necessary to have an amp to power the new speakers? thanks

 

anyone? also, will 6x9's fit in the front?

 

I have 6x9's up front and 61/2's in the rears. Just need the adapters and you set. Fostgate - front and Infinities in back.

 

where do i get the adapters?

 

Any stereo shop can make them from MDF or you can buy from Mr Marv or Taco Tunes online.

PM Italyn Stylion he made mine for me and did a great job!

 

A member here: hookedonelectronics makes some adapters and they look great with a reasonable price....check out the buy/trade/sell section. GL!

 

Nice!

 

I got my adapters from Mr. Marv. I told him what speakers I bought and he made them for my specific application.

I have 6x9's in the front, and Mr. Marv knew right away that I needed extra deep adapters and he hooked me up with exactly what I needed.
