my 299 system

Here goes folks!

Kickpanels: 3.5” Wolfengang 80w 86db (pr) $25
Center dash: 4x6 Pioneer 20w 91 db $20
Trunk: 10” Pioneer sub, 120w 90 db $50

Head Unit: VR3 4x21w, 4 RCA outs $85
Amp: Rampage 4x75 RMS with 50-250Hz low pass $85

High pass filters for 3.5”: 200 Hz 6db $6
Resistors for 4x6”: Pair 25w 27 ohm $6
Power wire: 20’ 10 gauge $5
Speaker wire 18 ga $5

Sub box 9x15x15x½” MDF $12
1965 four door ford uses a 40 amp alternator

I have spent a lot of time cruising the 12 volt. Learned here how to make kickpanel pods, what filters and resistors are for and much more. While no one will accuse me of overspending, I do want to get the maximum out of my $300 investment.
The install will finish up this weekend. Right now I worry the most about the center dash speaker – how can I (if I can) get it to gracefully fill between the subwoofer and the kickpanel speakers? But maybe there are other weak links too?

Thanks for all your help, guys!
