Greetings audio enthusiasts, and thank you for all your help thus far

I've finally run into a bit of cash and its time to add some sub bass to my system:
Step 1: Pioneer DEH 5250
Step 2: Dynamat Bulkpack Xtreme
Step 3: Crescendo Opus 8.6
Step 4: Genesis Profile2 Ultra
Step 5: Sub/s & amplification

I'm going for SQ for the set-up but I would really appreciate a sub bass set-up that can go very loud as well. I have a few spare sheets of dynamat to use in the boot for keeping vibrations to a minimum, and I only need a short length of 8g from my centre console to wherever I place the amp
-I have a budget of $800 tops for sub+amp
-I don't mind building an enclosure, but a removeable prefabricated box would be ideal
-new or secondhand is fine (i live in brisbane)

I had a quick look through some reviews on ME and found this one, but I would like a bit more information on it (their UK website seems to be down)

The sole purpose of the amp is just to power the sub, so I should go for a monoblock rather than a bridged 2 channel?
Of $800, would you spend more on the amp and less on the sub, or around the same on each?

Thoughts, suggestions?


Cheers

I would definitely look at 2nd hand gear with that budget. I would also:

- look for one large sub (15", 18") that works well in a ported enclosure. Subs I would look for include JBL W15Gti, Exodus Tempest, and I'm sure others can put in their 2c. I would use a ported enclosure simply because you want loud for cheap, and ported is a great way of doing this. A well executed ported enclosure should still have plenty of sound qualities in it. I would also look for one sub rather than 2 simply because you don't have heaps of cash to throw around.
- build your own enclosure. They're pretty simple, and much cheaper.
- look for a 2nd hand monoblock amp on this forum. You should match the amp to your sub, not the other way round. I'd be looking for about 500w-1000w for that price ($400-450)

Go down this path:
- work out approximately how much space you can sacrifice to your sub box in litres
- find 5 subs that will work well in that space
- get one thats cheap
- then build the enclosure to the sub's specifications
- then purchase an amp that will give the most watts for the sub's coil configuration.
