Hi all, just a quick question really as I don't know much about sound systems. I've got 2 x 10" subs in a sealed box, which are currently being powered by this amp: http://www.theloudest.co.uk/?sectionid=2&page=view_product&product_id=76 The 2 subs are these: http://www.xplodsony.com/xplod/subwoofers/XS-L104P5B They seem to work 'ok' but I noticed that when I disconnect one of the subs, the quality of bass I get out of the remaining sub is better [it sounds more bassy / less distorted / more powerful]. I read a bit on Class D amplifiers and it sounds like I need a Class D instead of what I've got already as I only need to power the 2 subs from an amp]. Can someone advise me as to what type of amp I should buy please? Thanks!
