I have 2 car audio subwoofers from my old boot install that I will be using.
They are Alpine Type-R's. Model 1221D.
Both are dual 2ohm subwoofers, so one sub per channel on the amp with each sub showing a 4ohm load.
Not ideal, but they work pretty nicely in WinISD in the 7-8 cu^ft enclosure tuned @ 20hz.
Specs:
Qts: 0.382
Qms: 8.680
Vas: 58L
Qes: 0.400
Fs: 27Hz
SPL: 86.59dB
Xmax: 13.3mm
Xdamage: 27.5mm
Sd: 0.0467 m^2
Thanks for showing interest.
Any advice would be greatly appreciated, as this is a first build for me.
