Finally finished installing a Alpine amp, and speakers. And i am pleased with the results it nice to cruz down the inter state at 80mph and here the radio nice and clear with out all that distortsion. Speakers are Alpine SPS-400 140watts peak - 45 wattsRMS and the amp is a Alpine KTP-445 45W RMSX4 It took some doing but finally have it in and working. Its only 2.5"WX1.75"HX7"L so it fit nicely in the front farring. It comes as a plug in to the Alpine stero so i had to cut off the plugs and Hard wire it. And that was the worst part of it.No wire diagram for the amp. A 2hr job that took 4days.
