memphisbasshead Posted May 31, 2010 Author Report Share Posted May 31, 2010 you really think that amp is 90% efficient? and why the hell did you replace the fuses with bigger ones? they were sized for 30 for a reason. because the 30 amp fuses blew. and i have had the amp with the 40 amp fuses for 2 months now and i have had no problems at all.

Guest Posted May 31, 2010 Report Share Posted May 31, 2010 because the 30 amp fuses blew. and i have had the amp with the 40 amp fuses for 2 months now and i have had no problems at all. do whatever you want to that amp, you're never gonna change the fact that its a kenwood...and i'd like to see this "birthsheet" that said 13xxrms at whatever ohm load. and proof that its 90% efficient. sorry but i think you're talking out of your ass with those figures.

chapo123 Posted May 31, 2010 Report Share Posted May 31, 2010 x2 i doubt that kenwood does rated rms. Steve I don't know why but everytime I see your new paint I want a Dr. Pepper...... is this normal? heres an analogy for you. running a high power stereo without a fuse is like having unprotected sex with that hot chick at the bar with the sketchy sexual history. Sure you may be fine and nothing happens but that one time something does happen you're fucked. i dont want woofer broke like bass sound clip clip and voice coil overheat 2 sa12s, saz1500 build log http://www.stevemeadedesigns.com/board/topic/91183-chapo123s-sundown-build-log/page__gopid__1250604entry1250604 Link to comment Share on other sites More sharing options...
thumper806.yellowcity Posted May 31, 2010 Report Share Posted May 31, 2010 There is a reason they kept blowing!!I believe the manftr. Knows what the amp can handle,upgrading the fuses is just asking for a problem,but for that amp I'd say an mtx 7500 haha.

TeejayBee Posted May 31, 2010 Report Share Posted May 31, 2010 you only want to spend 250$ total and my Memphis amp cost me 1.1k$ loolz Link to comment Share on other sites More sharing options...
memphisbasshead Posted May 31, 2010 Author Report Share Posted May 31, 2010 x2 i doubt that kenwood does rated rms. this kenwood amp is cea certified!! so why would it not put out its rated power?

AssKicker Posted May 31, 2010 Report Share Posted May 31, 2010 Because 90A of current will not give you 1500+ @ 1 ohm. My hifonics uses 140A to make 1600 so do the math. Link to comment Share on other sites More sharing options...

Knows what the amp can handle,upgrading the fuses is just asking for a problem,but for that amp I'd say an mtx 7500 haha. it kept blowing with 30 amp fuses then when i tried using 40 amp fuses it worked fine and it has been working perfect for 2 months without overheating. and is an mtx 7500 any good?

parton226 Posted May 31, 2010 Report Share Posted May 31, 2010 it kept blowing with 30 amp fuses then when i tried using 40 amp fuses it worked fine and it has been working perfect for 2 months without overheating. and is an mtx 7500 any good? you should still never put higher rated fuses in something because the 30A fuses that it CALLS for blows. thats just askin for trouble. its rated for 30A because thats ALL that should go through that circuit at one time. If more goes through than it should it means there is a problem, could be short or something but whatever, because more current is flowing through that circuit than the wires/load can take. parton226 Link to comment Share on other sites More sharing options...
