My 1991 crx has an Alpine 9807 headunit with the SIRALP1 sirius tuner. Next inline is an Alpine 4 Channel amp bridged on my components for the fronts. Then for bass i have an old Zapco Studio 500 running my RE XXX 15" sub. Old amp, but still runs with the best of them. Powering the whole system is a 200 amp Iraggi Alternator.

My crx from outside my messy garage.

My xxx next to a boston pro, and MA audio subs

Zapco under a coverpanel I made while I was bored one day.
