i have a 2007 mustang with the shaker 500 system in it. I'm replacing the stock speakers with JL Audio 5x7's and JL Audio 8" subs in each door.
I want to (if possible) keep the stock head unit. But at the same time, I'm willing to replace it if it is worth the extra money. I like the double din setup just dont want to pay that much more if it's not needed.
Here's what I'm looking for answers to:
I have access to either a 300 watt, 4 channel amp and a 450 watt, 4 channel amp. Which one would be better in my case?
Also, recommendations as far as what I would need if I kept the stock head unit, or recommendations on replacing it.
Replace the head unit with a nice double din. I like Alpine, personally.
More power is better. Go 450 vs 300.
Which 8s are you getting? Which 5x7s?
I have a set of ZR800s that I still haven't installed in my ride, because it's going to require fiberglass work. I am jealous of the Mustangs with the spot for the 8 in the door.
Use sound deadening like crazy on your doors. When it seems like plenty, add more. It's not so much about rattles, but about eliminating flex in the panels, which robs energy that could have been more sound.
If it were mine, I'd install the ZR800 for dedicated midbass, and then add a real substage with a pair of 12s, or something similar. I don't see you getting true subs in the doors to sound good enough, but then again, I guess that depends on your opinion of "good enough".
