just got two of these. this 10in gets a perfect 10. i installed them each in their own small sealed box and have them waggin under both dropdown bolster seats in my boat. i also picked up a pdx m12 alpine mono amp. 1200rms at 4 2 or1 ohms. iam wired to 4ohms for simplicity and reliability. these subs are great, the sound quality had me stumped on how i wanted to tune my system. I was able to set the xover higher to allow a more full range bass output with plenty of volume and no highrange pop and now the music is super full and realistic. this was set to enjoy music where an actual bass guitar was used in the recording, and not synth bass. on the other hand, i then tuned for sub bass and was amazed at the ultra low bass pumping rap and [email protected]
pumping out theses small 10s. its doesnt matter the music you like. and even if you dont like alpine. i would give these a try. and go sealed in your boats if you like the way bass sounds.
