I have 2 PDX alpine 400.1 , and I would recommend them for several reasons. One, they put out 100 watts RMS regardless of the impedance (no math), and they are bridgeable 200x2 + they are very small and can be mounted anywhere. Go to bestbuy ASAP they are in the midst of discontinuing them (clearance) talk to a manager. I bought 2 for 325.00 + tax. I was happy as S**it, considering MSRP is 499.00 each. You should beable to get one for no more than 250 300, worth every dime!
