Amplifier died vHalp

Currently I have my car stereo set up with a line out converter…

I have an Alpine MRP-m500 amp with a Alpine Type R10 subwoofer…

I did the 9volt test to see if the sub was blown and its not..

I unplugged the RCAs from the stereo and plugged in my mp3 player with RCA output to the amp and it doesn’t work for shit.

so my assumption is its gotta be the amp.

I bought the thing at Best Buy a about 2 years ago…I have no box and no receipt.

Thoughts on buying a new one, and taking back the old one?

APSM-1500 v.here:

Make rated power and then a little, teammate of mine had one wired at .3 on a Soundstream XXX 15 in his Tiburon, rise put it at .9, 16xx watts at that load. Nice little amps, and I stress little. Best value for amps there is right now.

will this be okay with my current sub? Alpine Type R10??

I’m starting to think its not the amp. I pulled out the amp and threw in a different one that I had laying around, that used to be on the sub…

still didn’t work.

I checked the ground for the Alpine amp and the fucking morons that installed the shit fucking screwed the wire down to a painted seat belt bracket. The screw has turned orange and I cannot get the fucker loose.

I’m going to take it to a trusted car audio place and have them re wire the whole system.

alpine amps are pretty bulletproof… in most cases, you have to try really hard to kill them… or be really stupid… they are like rockford fosgate, in that they can take a lot of abuse that would kill lesser amps… move the ground to a better spot, and it should come back to life… have them bench the amp in front of you, to check it before installing it though.

I shoulda posted that the blue light turned on showing power to the amp…can it turn on and function if the ground is messed me?

Where else can I ground to? Any spot in the truck with a bold?

yeah it could have very low amount of current, and still light up… sand a nice clean spot somewhere close to the amp on the cab, and be sure to use a non-anodized screw… hint: if the screw is black, it sucks.

the installers have it hooked up with a o clip..

I don’t have any..can I just sand down the area and wrap the wire around it? or is a o clip a necessity?

a ring spade, and a proper screw makes the best connection… bare wire does not always make a good connection… low current damages electronics.

This weekend I’m going to a local car audio place and purchasing a good 20 feet of 4 gauge wire. I guess the company that installed my first power kit used 8 gauge wire (if I’m not mistaking). I blew a fuse about 2 months ago, went to a different install company, and the guy was quite upset with 8 gauge wire. He insisted that I move to 4 gauge, which I’m sure was also a sales pitch. Either way, its not a bad move.

if it’s all copper wire, and truly 8awg… then it’s just fine, for power wire on that amp… as long as the ground is equal, or larger.

Question.

I drive a 2010 silverado…

when the sub hits, the fucking headlights dim pretty bad. When I’m driving at night, I have to turn the bass all the way down, or not listen to the music.

I read that possible going to a lower gauge wire could help…

thouhts?

do the big 3… upgrade the battery positive to alternator wire, battery ground to chassis wire, and the chassis to engine block wire.

I have no idea how to do any of that…probably going to cost three arms and a leg to have done.

didn’t die. had it bench tested at best buy for free…guy did it in front of me and it worked just fine.

It’s not that expensive. Get about 12′ of wire and you’ll be set. I’d do 4gauge for the B+ line, and 1/0 for the grounds.

you should do the same guage for everything.
