WTB: USED Efficient, cheap 4 or 2 channel ASAP

[alec14 10+ year member]

I'm looking to buy a decent, used 4 or 2 channel amp. I need it to be at least 50x4 @4 if it's a 4 channel, or 100x2 @2 on a 2 channel. Really not looking to spend over $50 shipped, but it depends on quality. Offer up, looking to buy ASAP!!

any trades you're looking for?

 

[babsuhl81 10+ year member]

Not really. All I need is some terminals and to build a box

 

[babsuhl81 10+ year member]

If you have some 0 ga terminals and a 0 to dual 4 ga distro plus some cash

I do have some 0 gauge terminals, some nice copper ones actually. And I have a 4-way JL Audio 0 gauge distro block. How much cash were you thinking?

Sorry for the delay in photos my phone is having issues syncing with my PC.

But here is what Jacob of Sundown audio had to say about the same amp that I traded in to him during the sundown audio trade in deal a few years back. This was a back up amp I had stored away, tested and works great too btw.

I am going to take some shots with my digital cam and pull them off that way.

None that I can remember, I used it as a front stage amp back in 08 with a pair of 6.5 and tweeters with passives. And I loaned it to a friend of mine and he ran a pair of JL Audio 10's at 4ohm with it and he never said anything about a turn on/off thump.

Take your time I am in no hurry, just throwning this out there as a cheap solution to help out a forum memeber.
