JL AUDIO 12W7H.O Problem - Advice Needed

[jolly_26 10+ year member]

The ground is equally as important as the pos. connection, and quite often causes problems in peoples first setups, or if done by an installer who doesn't really know what he's doing. As pro-rabbit said, I doubt it's a voltage issue.

Did that shop sell you a brand new arc amp, because that sucker looks used since the control plate looks scrached up.

Might be a bad amplifier, and I cannot believe a shop would let a system go out the door with the amplifier turning on and off like that you are not even pushing it at a 3ohm load.

Sometimes I cannot help myself! When I was new at this back in 91 I wish I had someone around that did not sugar coat things. If I was the op I would go back and question the authenticity of that amplifier being new or used.

I have ran my 12w7 off 500rms and it did just fine. Op find your sales slip go back to the shop and ask them to give you a new amplifier and make them take it out of the box and walk with them and watch them take your old one out and put the new one in.

I would also request them to show you where all wiring is ran and grounded and such. Take pics if your not sure if it's ok.

Their store is closed right now, but i will be back there 100% right away in the morning.. im starting to get the feeling that i was pretty much taken advantage of.. Does $500 seem reasonable for that amp+install despite the fact of it not being able to work properly?

For a BNIB version nope..decent deal for retail.

You could have bought a JL 1000/1 from craigslist and installed it yourself for less more then likely though.

The Arc is a good amplifier but I think they sold you a used/messed up one.

other than seeing the exterior of the amp and wear and tear on it, i suppose there is no real way of telling if it was actually new or not?

Also, the whole claim that the box is "faulty" and that the looseness of the box is whats causing the amp to shut off is quite a nonsense excuse is it not?

 

[pro-rabbit 5,000+ posts]

Indeed it is. While the box is not the best, there is nothing that would suggest it would cause the amp to go into protect. That is 100% BS.
