Sold Alpine MRP-F450 (4 Channel)

[GearGuy2001 10+ year member]

Up for sale is a near mint Alpine MRP F450, I have had it since I bought it brand new in January of 2007 (I may still have the receipt) but I thought it had a bad MOSFET so I purchased a new 4 channel amp (I was looking for a reason to upgrade). When I pulled it apart today everything looked good as you can see in the pictures.

Also I have tons of references (check my sig) but if you need me to post pics with my name I can do that

I don't think I have the covers for the sides but Ill check, I may only have one but Ill post what I find later.

*New Lower* Price is $130 + Shipping OBO

Trades: 2k-3k amp and Id add cash

Maybe other things that catch my interest

Specs:

4x70w @ 4 ohms

4x100w @ 2 ohms

2x200w @ 4ohms Bridged

so have you tested it?

Well here is what was happening, I have had it in my car and just took it out today when I had 6x8s in the rear channel 4 would sometimes go to XMAX now channel 3+4 are bridged and drive my passenger woofer which just recently blew, I havent bothered to reconnect everything with a new amp coming so soon but the board looks fine to me.

If you have any ideas on whats wrong, if anything or a way for me to test it I'm more then willing to do that.

Sorry that may come off like I was trying to hide that but I didnt think much about putting it in my first post.

Looking at the sides my gain was set a tad high on the 3-4 channel possibly causing clipping and the xover was set low compared to my drivers side. I adjusted it to match 1-2 channel hooked it back up and it sounds great.

I think my price was a little high so $130+Shipping might be more enticing
