After some research, here is my idea:

- Head unit: Alpine iDA-x100M-320
- Amp: Alpine MRP-F300 (to be installed in the trunk)
- Keep front speakers and Tweeters. I will just use the head unit crossover and adjust the amp gain to save them.
- Sub Kicker CVT652 (6.5") to be installed in the original sub space.

My questions:

- Will the subs be a direct fit? If so, do I need the original sub housing?
- As in previous thread, who in the Detroit metro area I could trust to do the job?

Thanks
