zagfuchs Posted November 3, 2014 Report Posted November 3, 2014 I was wondering what the advantages and disadvantages are to running a Class A/B amp on your subs were. Anyone who could throw some information my way, it would be greatly appreciated.
gckless Posted November 3, 2014 Report Posted November 3, 2014 Gonna be an electrical hog. Sonically, you may or may not hear a difference, all depends on your background and ears. Modern Class D has come a long way. What kind of power are you talking? "Clipping" is the biggest forum boner now. It's like witchcraft... it automatically explains just about everything people don't understand.

Broke_Audio_Addict Posted November 3, 2014 Report Posted November 3, 2014 Are we talking about high quality amps or low quality? Either way the a/b will be less efficient though. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.
zagfuchs Posted November 3, 2014 Author Report Posted November 3, 2014 I have two JL 300/4 amps I wanted to use.
Broke_Audio_Addict Posted November 3, 2014 Report Posted November 3, 2014 OK how are you wanting to run them and what are you trying to power? That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.
zagfuchs Posted November 3, 2014 Author Report Posted November 3, 2014 I would be powering two Kicker 07CVR122 subs. Since they are dual 2-ohm, the plan was to bridge the amp and run a channel to each voice coil. One amp powering each sub as a two-channel. I would put the amps in full range and set them with a mulitmeter, then run them through a separate crossover so I could adjust them simultaneously.
zagfuchs Posted November 3, 2014 Author Report Posted November 3, 2014 Would this setup work okay? It's pretty much the only option I can think of where I wouldn't have to buy anything.
jk13 Posted November 3, 2014 Report Posted November 3, 2014 No. JL Slash amps are 1.5 ohm stable stereo and 3 ohm stable bridged. Best you can do is one amp to two subs bridged at 4 ohm. No good way to run both amps on those woofers. Static drops are my bag.
BoomZoom808 Posted November 4, 2014 Report Posted November 4, 2014 Trade one of those JLs for a monoblock dont do it for long if you have to. Especially with those subs. 2010 Mazda 3s 2.5L Pioneer DEH-X9600BHS Knu OFC 1/0 SS Platinum AGM / XS Power XP750 Alpine PDX F-4 / Morel Maximo 5 + Coax 5 IA 10.1 / SSA XCON 12
zagfuchs Posted November 5, 2014 Author Report Posted November 5, 2014 Thanks for the help. I originally planned to get rid of one or both of these amps, but the friend I bought them from had suggested it might be able to be setup this way. Are the Hifonics amps good? I have been looking at them for a while now, seem like good prices and lots of good reviews.
