Alpine SPS M601 Type S Coaxial Speakers Review

I installed these on my Yamaha AR240 boat to replace stock speakers. I am shocked by both the sound quality and volume. I was ready to embark on a complete overhaul of my system, but now it was out of the question. There is no need to. I couldn't be happier with my purchase.

I bought this to replace the exact same model because the hole fits this speaker exactly. That's less than 6 1/2" since the real 6 1/2" speakers I ordered and returned don't fit in the small hole.

22ft bowrider with old Alpine MRV-F505 v-12 Expert 4-channel amplifier and new Alpine MRV-M500 mono subwoofer. Sony Marine MEXM70BT Head Unit. 2 SPS-M601 in the bow and 2 SPS-M601 in the middle of the boat, plus 2 SPR-M700 in the stern of the boat and a 10" SWR-M100 Alpine SUB in the ski compartment. Alone the m700s produce a very rich and full sound. Once I adjusted the gain of the amp so the 601 could handle the same volume levels as the 701 the 601 was a real asset.Adding speakers to the bow
