Alpine has always had a good reputation for me and these are no exception. I have a pair of these SWS -D4 and I have them running in parallel with a Boss Audio Riot amp. 3400 watts total. The sound is way more than i expected. I am very impressed at how they came. Wrapped up and everythihg. They sound awesome with no distortion at all. THEY THUMP. Couldn't ask for anything better. Thank you

Alpine SWS-10D4 rocks. I boxed it in a sealed enclosure that took the place of the console on my RAM 1500. Perfect. Plenty of base to bump most of my music without sacrificing usable space under the seats in my truck.
