Q
Hi, I have a 1991 single cab and I am 6'5" so can't afford to sacrifice leg room. Will these fit behind the seat and I can still put the seat setting all the way back? Or will I need to scoot the seat forward a little?

A
We are happy to check your 1991 single cab pickup and have product advisors who can be reached by calling 1-800-324-9695 who are able to get the specifics of your specific single cab pickup to check the information we have on it and available space for speaker boxes.

Greetings Atxel. Thank you for your question, but first we must have the year of your F150 to check if we measured behind the seats.

Looking for speakers for 1986 CJ7. Would this work?

Greetings Annette. Nice rig. These can work if you have a place for them. They are not water resistant, so you want to keep them dry. On another note, you would want to put an amplifier on these as well.

Yes. But I go not recommend them. Very poor sound quality even with a great receiver

They seem to work fine at low-volume without an amp. I will probably look at adding an amp in the future.Enter an answer to this question.

Q
I have a 2004 Taurus. Door component speakers figured out. I need a based suggestion for the the rear deck. You have the sevier mids that are 8 inched are those like a woofer plays mids and low lows. Will they hit. Do I need to get a full blown woofer instead?

I put these speakers in the cab of a work truck. The sound very good but the stereo does not have enough power make a lot of bass. I would recommend bass speakers. These seem to be good for mid bass.
