In a SQ system, is it better to run a monoblock to power your sub with a low impedence load, say 2 ohm. Or do you only do that for volume in a SPL system?

Good question - Many people will argue that Class D monoblocks are more suited to SPL and that a Proper SQ system should consist of a powerfull class A/B amp.

The only benefit i see from that is higher dampening factor, but if you get a monoblock with reasonable dampening factor to start with then it's not a problem.

I competed last year running an Earthquake monoblock with modest dampening factor on paper (still using it) and seemed to do quite well despite what some people might say.

Final Answer
The choice is yours, i have always used Class D monoblocks and had success, i have not been able to distinguish the difference between mine and those running class a/b, but some may have better hearing than me.....

Great thanks, I think i'll stick with my plan for the monoblocks.

Love the write-ups, they are very helpful for understanding it all!

the sub is sony, the amp audioline.

It sounds pretty good, dont need to spend that kinda money.

Your right you dont need to spend that sort of money -- but -- to get a Budget SQ or SPL system i think you do. You may have taken it out of context.
I said a basic system upgrade starts with a headunit change (costing maybe $300) then the next step would be some front splits, then a good quality 4 channel amp then a sub + box + wiring.

Your $360sub, box and amp combo doesn't include
- Headunit
- Wiring
- Splits

As mentioned
Splits would add $300+
Heaunit $300+
Wiring $80 +
Good quality 4 Channel amp (not 2 channel) $250+ difference

So thats $930 + your $360 = $1290

I was also allowing for a custom box to be built, installed and carpeted not a prefax one

If you note i actually said

While there is no fixed price ......

I never said you have to spend $1,500 i simply gave that figure as a guide

I've taken on board your comments and amended original post to say $1,000 - $1,500 ubdget.


At the end of the day if you wish to go absolute budgtet then you can get a system for

Co-Axils = $100
Headunit = $200
Cheap 4 channel amp = $150
Cheap Sub = $80
Wiring = $35
Total = $565

But in my opinion that is not a Budget SQ or SPL system, thats just a - budget system full stop....

Aaron, what in your opinion is the best suited front speaker to replace the standard premium sound ones in an EF front door application? :?

I assume you mean coaxials int he doors?

I do not normally give opinions on speaker type as there are so many i have not heard but from what i have heard.

I liked (and have actually owned all of the below speakers)
- JBL - (high power handlingh)
- MB Quartz (nice and clear and bright (metal dome tweeter can be a little bright at very high volumes)
- Pioneer (nice & smooth & readily available to audition)
- Jaycar (the ones with the titanimum swivel tweeter. It makes it easy to angle the tweeter for improved soundstage)


If you have a little more money then these 2 are very smooth and natural sounding but expect to pay $300 - $350 for them in co-axials
- Boston Accoustics
- Focal

You will get major benefits from sound deadening the doors throughly too.

Yeah naa that kind of budget is pretty spot on Aaron, when i think about it. My setup:

Alpine HU 787IE $399
Sub- Alpine Type S 12' (Including custom made box) $400
Axis Audio 2 channel amp $150
Wiring $100
Rear fill Alpine 6.5' Type S coax $150
Sound deading the boot $80 :)

Considering this is all i have atm the cost is still about $1000+

Then once the Front stage has been upgraded then it will be roughly $1500 ive spent on the whole system. To me thats a pretty decent budgeted system. sounds great as well.

So yeah i can definately agree with you on that one :)
