Let's try this as I don't really have a proper person to ask. Application is 1980 Firbird with very limited trunk space after the T-tops are stowed. Mids and highs are pretty good with aftermarket stuff though I plan to add an smaller amp to drive those soon instead of the Kenwood head unit. My main problem is box volume for what I hope to do. I'm hoping that your advice will help me get serious lows since I'm not trying to win a competition. I just sold my car with some big car audio stuff. I miss the bass so much I gotta have something...... and my truck's under seat box is pretty pathetic.
Number of subs preferred: 1
Size preferred (if configuration allows): 18!!! or 15
Budget: $500
Power to be used (which amp(s), include which resistance): Vintage 350W 2ohm since it drives down to 4Hz (no kidding) and yes, the motor is only "moving" at that point. I could use my 1500W 1ohm amp too but it's limited to playing about 28Hz regardless of what the spec says.
Space available (take measurements, do not guess): 1.5cuft (37 x 15 x 8") tapered at wheel wells minus MDF thickness. If the motor depth doesn't fit I can offset it to extend into the seat frame a bit. I'm pretty creative.
Goals: Play stupid lows
Listening habits: old school bass music, some of the newer digital bass music.
Preferred brands/subs/whatever: I like Skar pretty well so far
Thank you
