The big power your boat's system needs

If you've ever tried to power your boat's speakers with a marine radio, then you know that you need some serious power to get good sound out on the open water. Sporting a stylishly sleek profile, JBL's Marine A1504 amplifier will deliver 150 watts RMS to each of four separate high-performance speakers or component sets so your music will play loudly and clearly everywhere throughout your boat, fore and aft.

High-power applications

For maximum fun, you can bridge the amp to 2-channel mode and power a pair of high-performance speakers or subwoofers with 450 watts RMS each. You can also use this amp to power two speakers and a subwoofer in 3-channel mode, with 150 watts going to each of your full-range speakers and up to 450 watts going to the sub.

Works with almost any system

High- and low-pass filters help the amp to clarify and maximize the performance of your speakers and subs. Speaker-level inputs allow this amplifier to work in almost any system, even if you're keeping your boat's original radio. JBL includes the right adapters to make these high-level connections. They also build the amp with coated circuit boards and stainless steel connectors to ensure that this amp will rock on the water for many seasons to come.

Great price for a great product
Color: Coal Black
Excellent quality and great price to boot. Easy to assemble and folds up easily to be stored. We are using it as a privacy screen when we have company that needs to sleep on the couch and also to block off a hallway leading to a guest suite. It looks great and is as described in the ad

No.
Color: Coal Black, Color: Coal Black
This was horribly made and a nightmare to put together. You have to basically bend the bars to get the coverings attached. The sizes don't match. The stickers that label the parts are impossible to remove and if you do get them off theres a lot of residue left behind. On top of that once it was put together I noticed theres a big dirty foot print on it which is definitely not mine.

You have to add weight to it
Color: Coal Black
It does its job and it was easy to put together but it's a little on the flimsy side and it will easily be knocked down. So you're going to have to figure out a way to make the legs heavier? I used cinder blocks, single cinder blocks and it works just fine. Just know that it will knock over super easy

I have 2!
Color: Coal Black
My office is in my loft. But there are things along the wall I don’t want to look at. These work great. Hides what I don’t want to see & is a classy look in the room. Sturdy, easy to assemble, well made.
