Details:

I purchased a new vehicle few months ago and the integrated sound system wan't that bad I'm not young anymore. I also replaced the RCA input jacks a few years ago as they had been worn out, newer one is much higher quality. No missing terminal screws or anything like that. 4 x 200W RMS 2-Ohms.

Condition is used. 2 x 400W RMS Bridged 4-Ohms. I am this amps original owner and have used it in my daily driver for years, no issues. I used them with 4 ohm speakers.

The housing is a little beat up as shown in the images, but totally functional, mounting points were poorly designed my opinion. Multi-channel 4/3/2/1 channel configurations: 4 x 100W RMS 4-Ohms.
