Ya, its old, and its STEAM POWERED!!!!!!! LOL! Its an OLD Alpine 3505 amp! this baby is all original. the heat sink has a few minor blemishes. it does work, and work well it does. I run this little puppy on an old Orion XTR12DVC in a dual reflex bandpass enclosure and got 121 dB out of it!!!! (measured by my golden ear! ) It has the DIN plug so its ready to hook up to your patch cables. ( you will need female barrel conectors) the amp will include no wiring for the power supply, it is capable of running off of the ciggarette lighter circuit!!!!! this thing can run 4 speakers and a sub!!!! with no modification to your electrical system. Very simple and very RARE! It has been run in 4 cars, each has been a potential competion winner. I suggest that you bid on this amp ASAP! I wil sart the bidding at 20 bucks. the bidding will end when I feel i have made enough money off of it.... Dont miss out !!!!!!!!!!!!!! this is a prime example of old school alpine amps!!!!!! It would make your system shine..................... thank you
