Wierd Speaker Issue

Have a Cherokee with a poineer head unit with stock speakers. I decided i wanted to upgrade the front door speakers to a pair or Crystal Mobilesound 6.5s that i had from my previous vehicle. They were powered by an expternal amp in my previous setup. They were in perfect working condition when i removed them from my last car 2 years ago. They sat in the closet for that time.  I decided to power them with my head unit in this application. I removed the stocker and plugged in the crystal which came with an external crossover which i also used. the highs sound fine but theres no bass. The cone moves but doenst produce bass. It doesnt rattle like a blown speaker, it just doesnt produce bass. It does distort if i turn it up semi loud. I thought they were phased wrong, but that changed nothing. I tried eliminating the crossover, that did nothing.  I changed all the crossover points on the headunit, that did nothing.

The bass response of your new speakers may just not be as good as the bass response of your stock speakers.My ex once told me I have a perfect face for radio.

no its a cherokee se which is base model at its finest. No power anything so im pretty sure theres no amp

You mentioned a crossover in the deck. Did you bypass it completely? It should not be engaged at all, as you are using 1: the internal deck amplifier, and 2: supplied external passive crossovers.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

i tried bypassing it and enabling it. I think i have realized that thhe speakers must be blow. There really is no other option as far as i know
