Item(s) for Sale:

First up are the Alpines. Model numbers MRV-F405 and MRV-T505. These were built in Japan circa 1998 and are quite nice. I would keep and use them but I recently came across a great deal for a 12w6v2 and need more compatible amps.


Output Power at 12V:
4 x 40W @ 4 ohms (0.08% THD)
4 x 50W @ 2 ohms (0.3% THD)
2 x 100W @ 4 ohms (0.3% THD)
Output Power at 14.4V:
4 x 60W @ 4 ohms (0.08% THD)
4 x 80W @ 2 ohms (0.3% THD)
2 x 160W @ 4 ohms (0.3% THD)


Output Power at 12V:
2 x 50W @ 4 ohms (0.08% THD)
2 x 100W @ 2 ohms (0.3% THD)
1 x 200W @ 4 ohms (0.3% THD)
Output Power at 14.4V:
2 x 75W @ 4 ohms (0.08% THD)
2 x 150W @ 2 ohms (0.3% THD)
1 x 300W @ 4 ohms (0.3% THD)

From what I'm told these numbers are pretty underrated..

The beat up amp is a Rockford Fosgate p4004. It's quite a bit beat up as you can see in the pics and is missing a few speaker screws. I was also told it was missing a "receiver" piece in the speaker terminals. All I can say is that it worked when my buddy and I pulled it out of his car 3 years ago..and it's been sitting in his storage space since (not quite sure how it got so beat up and is now missing stuff) I'm selling it as is for cheap.

* 4 ohms: 50 watts x 4 chan.
* 2 ohms: 100 watts x 4 chan.
* Bridged, 4 ohms: 200 watts x 2 chan.

Item(s) Description/Condition:

The alpines look a little better in the pics than they do when you are holding them in your hand..but it's not that much different. I would say 7/10 on the cosmetic scale just because there are small chips and smudges all around. Great looking for almost 15 years old now.. They work great though!

The rockford looks crappy, 4/10. Selling as-is


I'd like $70 shipped on the T505 and $75 shipped on the F405.

I'd like $35 shipped on the Rockford
