I used to be really into car audio in late 90's, early 2000's but fell out of it. Back then I'd use nothing but Phoenix Gold amps, but it looks like they kind of went down the toilet after then.
I still have a big 15" subwoofer laying around and figured I'd pop it in my car. It's dual voice coil but I'll have to go measure it to figure what impedance each coil is. 500 watt RMS rating (but I used to have 900+ going to it no problem).
I'm looking for an amp to power it. What good brands now have solid entry level lines? Something comparable to how the old Phoenix Gold XS series were. I'm open to Class D.
