I am going to tinker with the amp bridge PCB maybe its a resistor blown or bad cap on that board. However I am not going to spen more than an hour trying to fix. Really what do you suggest for an external amp for a Sub that I can use on multiple subs as I grow my sub builds. I may want to tinker with others in the future and jusst think maybe a decent ext would do the trick....
I am not sure if I should go with one of those Behringer Inukes with DSP they run about 300 dollars? Have you seen those? Maybe a plain Behringer ep4000 or EP2000 ? Maybe one of those Dayton 1000W external units ?
What do you suggest?
Contact murrel about suggestions on fixing the amp. Got any pixs of the amp? Check the fuse in IEC plug receptacle.
Youve certainly got amp options.
Murrel sells a new version3 amp for the mfw which is really nice and setup perfectly for the sub you built, about 250-300.
If you buy a pro amp your gonna need a seperate high pass and probably some eq to get good results. Or buy one of those DSP models. Heres the thing about pro power you need a setup that will be power limited right at the maximum power handling of the sub to keep it in one piece. Orherwise an unexpectedly high signal could take out the sub since the amp will just blow right past the drivers limits.
sandbagger has some cap modded V2s hes selling. Who knows how long theyll last. ive got three of like that and i hope they keep pumping....... However i wouldnt pay more than about $150 shipped for one just not worth the risk.
Heres what I would do in this order. Try to fix amp with murrels help. Buy a v3 from Murrel. Go with the BASH 300 from PE for lile $120shipped and build an extra box on back to hold it or buy the 240watt external amp from PE for like $200. The 240 would be under powered.
If i were using pro power id scrap the MFW driver and get something that could handle a little more power. Pro power is not gonna work out to be power limited for that driver and would not be very durable otherwise. Think about a deiver that could handle the full power of one of a pro amps channels. And youll still need a high pass.
The PE titanc 15" looks good in that box but id have to model to see how much power it would take....... And im away crom home now.
Lots of options........
