Question: Can this AMP connect with a subwoofer? I have been trying to find a way and I cant seem to do so
Document: I ordered this amp for my 1990 Nissan Sentra. The first thing that happened to mine was that the plastic ring around the volume nob broke off,no big deal. Then i had to find a way to connect the power supply to my + - 12 volt car electrical system. No problem because I work with cars a lot. I used an old car charger and made some minor  modifications (cut off the sigg.
I'd initially adjusted the bass, treble and volume then left it alone. (Some reviews state the knobs, etc seem flimsy / cheap, I certainly agree but ... IT'S  A $16 AMP! )The real satisfaction is the sound is just FINE for this low-budget "critter".Honestly, I can't get over it! I'm listening to classic guitar right now & loving it.
Since the computer doesn't seem to be doing any frequency filtering on the output (which it thinks is a subwoofer) it works perfectly.If I go above 50% on the amp, I do get some hum out of it, but not much, and I just keep the power down just below that to keep the sound clean. With the computer's output volume up, I can more than adequately rock the house.
The case is sturdy metal, which appeals to the old school side of me (I hate plastic). It does have these wings that allow you to bolt it down to something--it might be for a car? Others have said theirs came without a power cord, but mine was fine.More and more I find that expensive, complex systems seem to come down to a stupid part, and that part is like a rock in your shoe.
Can't imagine a better bargain! ps. parts express low cost but not cheapest shipping.UPDATED: I have constructed the speaker boxes for the 6x9 JBL coaxials (91db efficient rated) 4 ohm and this amp can drive them for most listening situations. If you are trying to run a dance party, you may need something bigger for LOUD music. I have outgrown ear-damage volume and find it works great for my levels.
Got mine yesterday. No power supply. I'm using it to power a 15" sub. I know that sounds ridiculous but it works! I needed something quiet, and this little amp gets the job done, using a power supply that I salvaged from an outdated scanner.I recommend trying it for anything (even unreasonable applications) but be prepared to find your own 12v 2A power supply.Update -I had heard the expression "bridged output" before and figured out how to do it with this amp.
I managed to make it useable by bending it back to more-or-less straight by hand.I will revisit this review if I hook up larger speakers or if I connect a subwoofer, or if it should blow up.
This thing sits on my computer desk comfortably and drives two Pioneer sp-bs22-lr perfectly fine. If you just need to drive a couple of speakers of under 80W, get this instead of bothering about a big expensive receiver.I could not connect a sub to this but there are ways around it. I bought 3 cables for under 5 dollars and I now have a powered subwoofer added to the setup.
So i finally got this product and was just dying to connect it to my PC in the ultimate hope of Deafening myself. Test the product only to find that the left side speaker ports does not work. Is it that product testing isn't done anymore? I have ordered several items from amazon and of late been receiving defective products.
I had the very basic problem of wanting to listen to streaming music on my home office desktop PC, and owning a pair of high quality bookshelf monitor speakers, I just wanted to connect them together. My first attempt was to find a S/PDIF amp, since my PC has a S/PDIF out. Well short of a huge home theater A/V system, this interface seems to be dead, as an amp input anyway. I found this and decided to give it a try.
Answer: Hello, I connected my Dual 12" 4 ohm SVC to the amp just fine. You run the two wires from the woofer to either the right or the left pos. and neg. terminals. Tip: make sure your woofer is rated for less than 4 ohms or the amp may over heat.It ran this woofer pretty loud without distorting!Good luck!
