I just installed my new system and I am a bit disappointed. I'm trying to figure out where I went wrong, or whether I was just expecting too much of the HU's internal amp.
Here is the setup: Alpine CDA-7894 HU powering Alpine SPR-174A 6.5" coaxials. I did not think I would need an external amp with the 27W per channel RMS the HU puts out (60W per channel peak). I am not looking for sonic booms here, just a decently powered and matched system.
I replaced the stock HU first with the Alpine 7894 and that made a huge difference from my stock setup. But replacing the stock 5"x7" Ford speakers with the Alpine SPR-174A coaxials really didn't seem to give me a noticeable improvement. I expected a drastic difference with the upgraded speakers (they are rated at 40W RMS and they use an external 12db crossover).
Is my 27W per channel RMS Alpine HU just underpowering my 40W RMS Alpine speakers? I really expected more out of this setup. Any thoughts would be greatly appreciated. Tx!
