I need an amp to power two sets of Alpine SPR68 6x8 coaxial door speakers. They have a 100W max rms. Trying to keep it around $300. Will be used with a stock Ford head unit for now, but will eventually be upgraded to an Alpine CDE-123 CD receiver.
I would make a suggestion to you of the SoundStream LiL Wonder LW4.620 4/2ch amplifier, for under $150 new, a refurb prob under $120,Small, and plenty of power, and will be plenty for your speakers,Just a suggestion to you.
I like the PPI Phantom P900.4 for most people looking for a 4 channel amp, but it doesn't have high level inputs. This means you'll need to buy a 4 channel LOC, which cuts into your money for the Alpine head unit upgrade.
