Dayton sub amp
Planning to power my new sub, a mkIII 15", with the Dayton HPSA 1000-R. Its the rack mount unit not the plate amp. Is this to much power for the single sub in a 3 or 4 cube sealed enclosure. Any thoughts on this. I need all the advice I can gather also.

I'm sort of surprised no one has replied. I know that ep2500's are the most common amp for diy subs, but running it bridged to a single 4ohm mkIII sounds like a recipe for burnt voice coil. The 1000 watt Dayton "rack mount" looks like it may better meet my needs. I don't want a plate amp because of the extra RCA's and 110v cables I would have to route thru the walls. Using the rack mount Dayton reduces the cable routing to a single run of 10/2 SO cord. Has anyone ever seen or used this amp. I have never even seen a DIY sub in a home environment. Not many fans of HT in West Virginia, especially my part. Thanks in advance.

For one, you didn't include links so the people have to go searching.

Here's the amp

Here's the driver

My comments are that under most circumstances it is better to have an amp that delivers twice the rated power of the driver to avoid losing headroom. It's up to you to use common sense with the gain control.

If you go to the ratings screen for the titanic 15'kit,@ parts express people seem very happy with what is, a very similar set-up to what your doing. I have a 15" titanic in a 340l ported cab and it easily bottoms with my 350W plate amp. X-mech happens within a few MM's of x-max so be carefull. Ive destroyed a couple of those drivers. Hope this helps.

IMo, An Sub amp > 500 W RMS is a minimum req.

Thanks to all who responded. Cal, I don't know how to post links. I will find out how before I post another question. So if the gains are set to minimum, the vc wont melt? bjorno, thanks for posting the charts. I don't really understand all of them but I will research them to gain a bit better understanding. Eventually, I will add a BFD as my knowledge increases and am better able to utilize all its features. If I can get 90 or 95 db at 30 hz with just an ep2500 and the mkIII, that will be a good starting point for me. As I mentioned earlier this is my first home sub build, so sealed is easiest for me build and tune. If I eventually can get down to 20hz at about 100db in room I would be well pleased. Any further comments or suggestions will be considered and are appreciated.
