Yes, the sealed enclosure gives tighter, cleaner bass than ported, but I know I'm not feeding the sub enough power. I got the 421 amp mainly due to budget constraints, and I wanted to go sealed because of SQ. I think I am going to try putting it in a ported box just to see which I prefer.

I will definitely save the sealed enclosure, I spent a lot of time building it and it is perfect. It's carpeted, glued and screwed 3/4" MDF with silicon sealed insides and a high end gold plated banana plug speaker wire cup in the rear. I'm proud of it, especially since it is my first enclosure. I'm sure I couldn't buy the same quality in a store. At some point in the future I will get a more powerful amp for the sub and try the sealed enclosure again. I also will get a new head unit at some point with higher voltage pre-outs.

I'll keep everyone posted on my progress. I know I have a sub capable of some serious bass, I just need to keep tweaking things until I find the right combination of box, amp and head unit settings. The whole thing is a learning experience for me anyway. I just hope it doesn't get to be an expensive learning experience.

Hey guys,

sorry for the shameless sales promotion here, but I have decided that I want to get a bigger amp to power this thing. I need something that will do at least 350 watts rms at 4 ohms. I am going to sell the MTX 421. The amp is awesome, just not enough power for my particular sub. For anyone with a 2 ohm sub, this thing will pack over 420 watts RMS. If anyone is interested in buying it, it is 3 days old, perfect absolute brand new condition and it was purchased from an MTX authorized dealer (sounddomain). I got it for $171.90 shipped. If anyone is interested, let me know, I'll take any reasonable offer to unload it. jrussell38@kc.rr.com.
