My opinion is you spent above and beyond necessity. You could have had quite a bit of performance parts for that money or even a trip or two depending.
Not everything is about performance…engine wise that is. I know that you’ll love the sound of that. What door/deck speakers are you using? I still need to get an amp for my door/deck speakers, plus install the door speakers…they don’t fit right.
I have Alpine Type R speakers int he doors and rear dash. they are pretty nice still. Maybe next year I will upgrade those but for now they should do just fine.
