Why? I only have space for an amp 13"x9.5". I looked into the rockford p1000x5d but thought the alpine was better, and the jl hd is waaaay too expensive...I would change the amp if I were you.
I dont like the look of the pioneer or how I would you have to work so much to get anywhere opposed to the alpine which is just the push of a button. Plus the used alpine is around $200 where the pioneer is like $370 The sub I went with ID because of what I read plus the fact I already have ID comps...I know a little weird but thats me lolnothing wrong with that amp. it sounds fine u would be hard pressed to find a problem with it other than price. as far as the headuint i would look at the deh-80prs for a good active capable deck with a good eq. the sub is fine though i would rather an sundown sa based purely on the fact that it can sound just a good as the id and still have the ability to get loud. jacob himself has posted info to back this up
I know someone selling one just waiting on a price. I am not limited to that alpine I was originally looking new at a hd138bt but if I can save money to around $200ish then who knows...You have lined up a used CDA-9887 ?Or are looking for one?
