Advice: will I have enough high frequency quality / volume?

[Adam LaFountain]

I am planning out a system for my ‘04 Ram 1500 with the Infinity 7-speaker system. I havnt bought anything yet but I already have a 10in sub from my last car. My current plan is a head unit and a separate DSP/amp unit.

Stock system:
2x 3.5” dashboard speakers
2x 6x9” front door speakers
2x 5.25” rear door speakers
1x 2.5” center dashboard speaker

New system:
2x new 3.5” dashboard speakers
2x new 5.25” front door speakers
2x new 6.5” rear door speakers
10” rear seat subwoofer
?? 2.5” center dash at all ??

I know 5.25s fit in the front and 6.5s fit in the rear. I did this to try and get more high frequencies in the front because I know I’ll have more than enough bass from the sub and 6.5s.

Will the two 3.5s in the dash be enough to carry the tweeter’s job? The smallest diameter stock is the single 2.5 in the center, this seems odd to me there’s no smaller speaker for a tweeter.

I thought about getting rid of it and letting the other 6 speakers do the work because I’m lost in what to do about the center speaker. How should I wire a center speaker if my DSP/amp only does left and right? I looked at the factory wiring diagram and there was a wire for the “center” speaker, how would this work since almost every audio file is only left/right?

Thanks in advance for any help!

Some people forgo the 3.5s and just put tweeters in there. Now, if the 5.25"s have a tweeter in them, it may be too bright in the front to where the other frequencies will be drowned out. So 3.5s may not be too bad.

I would forgo the center channel. If it still nags you it not being there, CDT sells a center channel speaker that uses L&R to create that effect.

Thanks for the advice. Any tips on how to replace the 3.5s with tweeters? I know the wiring is the same but mounting a tweeter there seems like it might be too small to fit in the cutout.

You could use an ABS sheet. Cut the 3.5" circles to the size of the mounting holes, then cut the holes for the tweeters to mount flush.

If your mounting it behind the stock grille then you can do the same thing or make an adapter out of 1/4" MDF
If its behind the grille then you won't be able to see it of you paint it black
Not that there is anything wrong with using ABS.
I just hate cutting it for some reason plus its not that easy to get around here and I have no patience for ordering online when I'm mid project

Thanks again, my plan was to not use any 2-way speakers expect the 6.5”s in the rear doors. So if the 5.25”s in the front doors did not have tweeters, do you think 1.5” dashboard tweeters wiuld be enough? My only concern is lack of a driver in between those sizes leaving out that frequency range. I could also consider putting the 6.5” two ways in front and the 5.25”s in the rear. Do you think the full range would proper representation then?

I used something like this for the tweeters. Should be able to bend around, fit into the holes for tweeter and the 3.5 mount.

I don't have any pictures of mine, but here's an example.
