Amp naturally get hot but not hot enough to burn your finger.if all the speakers working,no distorted sound(sound clear),the problem might be the ventilation(free air flow) of amp.check the blower fan if working or check the exhaust holes maybe it is blocked. here are the other reasons; 1.)speaker wires touched the chassis ground. 2.)mismatched speaker to amp impedance. 3)overdrive input or u tap low input(from amp) to high output(of stereo) 4.)ur amp is out of bias. u need an audio technician for this... hope this help u...

Just hooked up the cde 100 and can't get my amp to power up


Solved it by attaching the very small hot wire, that is located on the RCA cablethat runs to the amp, that looks very unimportant, but is very very important to a accessory hot wire. Problem solved. Plays like a champ.

I just picked up a 12" type r in a box with a alpine m 350 how do I know what kind of type R I have without taking it out of the box?? and how do i hook it up to this amp??


Not to insult you in any way but u need to know how to wire into car's electrical system at the battery then to a fuse then to the amp and then output the signal from the deck to the amp.. finally to the subwoofer. you need to hook up 12V constant battery power , then remote from the deck ,ground wire from amp to chasis for power.. then wire to sub.

When I hook my JL W7 sub to my alpine mrd m1005 amp the sub is pushed out and stays that way


Hello christensen7,

It sounds like there's DC current on the amp output terminals. Disconnect the sub and test the output with a multimeter. If there's DC there, most likely the amp is shorted internally and needs repair.

Hope this helps.

When I hook my JL W7 sub to my alpine mrd m1005


You need to have the amp bench tested at a car audio shop. Sounds like a dead short in the amp. Try turning the crossover on the sub "off" and connect any other speaker to it. if you have the same outcome, your amp needs serviced. Post a comment with your results and if I can think of anything else you could try beyond that I will. Hope this helps

Sub cutting out


Check the 12v wire running from the battery to the amplifier. Also the sony explode is a garbage subwoofer compared to the Alpine.. sony (they say 1200w max but its more like 100w to power the thing) Amp could be going. Is the amplifier hot when running. If there is a burnt smell comming from the amp, its the amplifier

Alpine MRD-M1005 Subwoofer Amp Problem


He may be right! You might try finding a new source of contact for your ground cause it may not be sufficent enough to ground to, also make sure that no wires from the back of your radio have any wires sticking out touching other interfering things that could possibly be causing the noise

I would say any decent pair of 12" or 15" (single 4 ohm voice coil) subs that can handle at least 500W rms would work. The rest is going to be based on cost, type of box, type of music, etc.
