I have recently purchased a Kenwood KDC-W6031 Head unit and a set of Alpine SPS 690a 6x9 speakers. I am looking for an amplifier to improve the quality of sound and give a boost in volume. I was wondering if you would be able to help recommend me one.
Thank you very much.

If you just want to run the 6x9's.You want to look at the RMS watts for your 6x9's and the ohms of each. Match the amp to that. Most likely they are 4 ohms each. Some speakers just have the max watts. RMS will be half of the max.
