Subwoofers cut out while driving but amp LED light is still on...

I have 2 ten inch kenwood subwoofers hooked up to a 450 mono Alpine amp which is hooked up to a pioneer deck. i have had this system for a little over a year and never had a problem with amp or subs, subs do not appear to be blown but have not yet been tested on another amp. all fuses are ok and all wires have been traced. i just can't figure out what the problem is. does anyone have any suggestions becuase i don't have the money to bring it to get fixed and really want my subs back. thanks

To test if subs are blown push them in with your hand lightly and listen for any crunch noise if you hear one then they are blown

What amp would be better to use with what speakers/sub? I have a KAC-7202 kenwood 920W maximum power (150wX2 RMS, 4ohms) (230wX2 RMS 2ohms) and then the other amp I have is a Alpine MRP-M500 mono power...


I'm using that Alpine right now for 2-12" subs and I have compared it to 6 or 7 other amps this month and most were 4 channel 150Watt/Channel Bridged to 300Watts x 2 and found the Alpine to be superior in both sound quality and loudness. The Alpine has also not turned off even with full volume for hours at a time, Very solid amp I was very surprised due to it's size!

Wiring speakers to 2 ohm for most power


If you hook 2-4 ohm speakers in parallel that will divide Z into 2 ohms. That will pull a lot of power and drive hard the amp.
So if you have 4 channel outputs and had 8 speakers that would be the same. If you have 4 speakers and 2 outputs then 2 per output or if you have an odd number you would have to put one in series with the other 2.
Series means you hook output + to spkr+ then spkr- to spkr+ of the next, while parallel is keep the same polarity across them and in not so much of a loop. I hope this helps.

How to wire 2 alpine typre r 1242 to an alpine pdx1000 mono amp??


If they are single voice coil, just hook one up to the amp (bridged) like normal and run a jumper wire from the positive of the sub to the positive of the second one, then do the same for the negative....This will give you a lower ohmage, thus better bass!!!

When volume turned up subs pop then immediatly produce no sound


u might have to turned your amp so u can play both subs your amp might be to small to run both subs at the same time an u gotta play around with the settings on your cd player so when u blasted your subs it has that nice bass to it not that poping sound.
