Want to build a Class D monoblock Car amp
Well, it is pretty much simple from the title.
I would like to build a monoblock car amp that would output about 1000-1100 watts rms at 1 or 4 ohms. Is this possible and would I get started?
I really love doing DIY projects, and I figure why not an amp? I am savy with electronics, soldering and all that but do not have a lot of experience in complex circuitry such as an auto amp.
are there any kits or things like this because i have searched for days without any luck. I am willing to spend up to $200. or should i just buy a commercial amp? the thing is it is much more cost effective to build it myself and i love the learning experience.
any suggestions? thanks
there are some kits, but I not sure that any 1R stabil, 2 and 4 is out there
making it yourself...will take you so much time you don't want, its very hard to make something work right at that power and load impedance, not for beginers
And price could be an issue here too, am not sure if it is not better to buy one already made for this
for kits, look 41Hz.com or similar
I suggest just buying an amp.
The power supply for an ampler in that power range needs to be very robust and will be difficult if not impossible for an inexperienced person to build.
$200 can get you a ridiculously powerful amp these days, just look around and try to stay away from local rip-off shops.
Here are good examples of what $200 can get you (even though they are refurbs).......
thx for your responses guys, good to know
i will come back to this site though if i would go ahead and try to build a new receiver/amp for my ht system. thx to all
actually, i was looking at this amp kit from 41hz
how many watts would this give me? it says it supplys at least 2x30A (outputs i guess)? meaning 60 A at 12v = 720w max? right?
well obviously it will distort at peak levels but i could use 2 of em in tandem, 1 for each 500w rms sub?
would this work? it just does not say what the input and output voltages are.
I would you AMP2 or AMP7
Amp2 is 2x 450w into 4R @ +/-60v
Amp7 is 2x 900w into 2R @ +/-60v
Both are GREAT, amp7 is better it also has 3oz CU pcb!
Where will you get a switching power supply to power this amp kit? How will you build the case/heatsink?
well i would need a gain control, remote if possible, mosfet power supply, maybe some crossovers/filters, i can make the case/heatsink out of aluminum from my old amp, actually i can use old cadence amp's case (and maybe even power supply?) for this build, here is what my old amp looks like (nice solid alum (alloy?) heatsinks)
ill post some internal shots tomorrow morning. maybe i can use the add-ons like the crossovers/filters and whatnots from my old amp and integrate it with the amp7 kit?
btw the amp 7 kit is 900w x2 (2 channels right?) would it be stable at 4ohms and how many watts would it be at 4 ohms?
i was looking at the amp7 kit description and it says now they offer it with a PS so that would take care of that.
I really would like to start a project like this, so I would like to know exactly what I would need besides the kit to get this to work with 2 500w rms subs at either 1R or 4R side by side in a sealed box. the configurations for these subs allow me only to set it at 1R or 4R.
I will post pics of my older amp to show you guys what the case looks like and if that case can be used to build this kit in.
I would also need a remote gain control, rca inputs, a possible subsonic filter, and also a crossover filter.
thank you to all that have helped me out so far.
