I have a kenwood KAC-8101D amp and about 2 weeks ago the bass started to cut out but i though it was because i was using a conver box for the rca's so i found the deck i wanted and i installed it and it started doing the same thing excep now i dont have any bass at all before it would cut out for few seconds and come back but now nothing the power light is on and i rewired the subs from the box out and i wanted to know if my amp is toast because if it is im just going to get a new one because its under warantee. thanks in advance

Re: amp on but no bass
1st make sure the speakers are not bad, check th eimpedance with a multimeter, the voice ciols should read 3.9 to 4.3 ohm's. if any of your subs are below this most likly the subs are bad. if they are ok make sure the ground for the amp is good. now the last thing is the amp. try another pair of speakers, even if it's smaller ones, just make sure they are 4 ohm speakers, keep the vol. very low during your test. if the other speakers do not work then have your amp serviced or replaced. good luck

it sounds like the power wire might be grounding out somewhere that you dont know of it could be by the fuse link so I would say put electrical tape on any exposed wire on the fuse link first if that don't work try change the power wire.
Yes, that would be the best connection for both the subs and the amp.
I'd wire the sub voice coils in series since the amp will not be stable at 2 ohms when the channels are bridged. The power will be somewhere between 100-200 watts RMS to each sub. While it's not pavement pounding, it should provide pretty good bass, especially if you tweak the crossover and boost settings for best bass response.
When you say the 40 Amp fuse blew. Was it your mains battery fuse or was it the fuse on the amplifier? If it was the fuse on the amplifier then you may have hurt the amplifier. The Kenwood KAC-8101D is a 1000 Watt monoblock amplifier. Therefore if you say that 1 of your woofers is not playing, then it is almost certainly blown if you are sure it is connected correctly. Try disconnecting it and only running the woofer that tries to play. If this woofer is still working correctly, you will notice a drastic drop if the sound of your bass. The reason for this is because you have changed the impedance load on your amplifier due to the fact that the other woofer is not working. Have your working woofer checked and replace the faulty woofer then you should be banging again.
