Jensen SPX-17 Problem. Need help

[chandlaa]

Hi, today I bought a Jensen SPX-17 subwoofer, a Pioneer VSX-D1011 amp, and some Wharfedales. I have my sub plugged into the Subwoofer pre-amp outpus on the amp with an RCA connection, my Wharfedales plugged into the speaker input and have my amp plugged into my laptop with a RCA-3.5mm jack converter. When I play music on my laptop, with my sub on full, the Wharfedale towers sound fine, but the Jensen only gets the really rumbly bits in songs, but it has no punch to it. For example, in techno songs, during the main beat, when a normal sub is thumping away at the floor, the Jensen is making a really quiet muffled sound. If anyone knows why this is happening, it would be very much apretiated
Cheers

hmm there could be numerous amounts of problems i see the post is almost a year old now but i you havent fixed it yet then try this check your rca subwoofer cable it may be stuffed or any cable your using. Or try using a different amp and a new plug and if that doesnt work take it back to the shop because theres probably a problem with your sub amp if the theres one built in

Thanks for the reply, but I'm no longer having trouble. To get it working, I bought a proper sub cable, changed it to 'plus' mode on the amp, and i'm now using an optical input from my laptop to amp instead of analog. Thanks anyway for your response
