ive had mtx, kenwood, sony, pioneer, lightning audio, and infinity. the 10" infinity reference lasted and sounded the best. you can see by the price ranges from the speakers i listed is a low budget. all but the infinitys blew within 2 days. i have a power acoustic 1600 watt amp for 3 years and had the infinitys for 2. the mtx are second on my list but yeah theres better out there. my amp is bad though 2 ohm 1600wt mono.....
