H.O Audio

Image dynamic subs are great for sq either the IDQ or ID Max both would sound great with nice output

Audioque amps do actual power and the ratings are at 1% distortion or lower. Most amp companies like fosgate and hifonics usually rate their amps over 1% which could mean at 3%,5% who knows. I have played with the Audio3500 amp first hand and it is a great amp that does a little more than rated.

Both companies have great customer service and also sell a great product. I have done testing with the Audioque 3500 amp and the Sundown 3000 and the Audioque was .4 db louder. Both companies do underrate the amps so It is just really a matter of style and power difference probably in this case.

I don;t know about the RD Alpha sub but I just got some of the Audioque subs for a demo vehicle build and it those things slam. I am running a audioque 3500 per sub at about half gain.

You should have enough power to run that with no problem but I would not use the cap if I were you. Every test I tried using a cap it hurt more than it helped.

Why not just stick with the Audioque amps as well, they put out full rated power and the price is great too.
