FS: JL 1000/1 v1 Amplifier & JL 12W7 in JL H.O. Box
I am selling my JL 1000/1 v1 amplifier. In good shape, works flawlessly, never opened or modified. Guaranteed to work great. Still hooked up so you can hear it. $400 obo
I will make a deal if you buy both.
I have my JL 12W7 up for sale, I'm moving onto bigger things so I don't need this anymore. It was never overpowered, underpowered, and never clipped. It only ever saw clean power. The cone was damaged awhile ago but was repaired (see pictures) however this does not affect the playability or sound whatsoever. Some of the carpeting on the edges are worn from the box being taken in and out of vehicles. Sounds great and the response is great in the JL designed box.
I am located in Mid-MI but I can meet within reason with details worked out.
Price is $500 obo, please keep mindless comments out of here and low balling will not be acknowledged.
