wired series/parallel to a four ohm load? 100 amp fuse between battery and cab , fuse before amp inside cab
amp is bridged
the reason i ask is my amp has fried twice ive only had it for 6 months the first time crunch fixed it no problems this time they are trying to tell me that i have it wired wrong
i opened the amp and a 1000uf capacitor is blown right beside the power wire input
does anyone know how to replace this capacitor i know its a surface mount but thats about it
i thank all of you for your input

if you have it infact wired series parrelel then it should be fine check this site out for wiring diagrams

ok they are wired right
i thought so
does anyone know how hard it would be to replace the blown capacitor and what all it would involve
ttocs on 07/6/2004 11:39:55
have you checked the impedence with a meter?
unless you are experinced in repairs I would not reccomend fixing the amp yourself. Too easy to mess things up....

i have replaced capacitors in old stereo amps for home audio and i do mean old 70's vintage equipment its a nice reciever my dad had an i love the thing for music not so good on home theater but it well sure pump out music loud and clear:) but anyway it wasnt too difficult to replace the capacitors in there but i did mess up a part next ti it and had to redo that one too... car amps are more compact and closer together so its going to raise the possibility of damaging another part.
ttocs on 07/6/2004 16:36:44
and in the 70's they didn't use surface mount technology.......

ok well im going to take it to a shop here in town how is the average repair cost anyone know
i also called crunch and they said that my subs are probably 3.8 ohms and that is what is causing this and basically told me its on me to fix it
ive never heard of this
this will be the second time this has happened the first time crunch fixed as under warranty
thanks for all your help

The subs are probably 3.X something ohms per coil in DC resistance. But if you have them wired correctly, a 4 ohm load is your end result to an AC signal input. Wiring these subs...
1. Wire sub A voice coils in series (you should read ~7.6 ohms on a DC Ohmeter)
2. Do the same for sub B
3. Now wire both subs in parallel (8//8 = 4 ohms) to the MONO bridged amp
===================================================
Crunch is blowing magic smoke up your fanny with that answer. Basically, it's their way of shifting the repair bill back to you as they know they make inferior products. If you did not know that when you bought it, you know it now. Just look at the results and their reply.
Replacing a surface mouted cap (SMT) is not hard, if you have some board level experience and the proper tools. If the mouting pads are under the CAP, a hot air knife is needed to melt the solder and remove the damaged cap. If the soldering pads are outside the caps parameter, a soldering gun or 35 watt pencil will usually do the job. Resolder using 60/40 alloy, rosin core flux type solder. (0.125" dia) is good here.
If you don't have any bench experience... better left to those who do. You could make a real mess of things and trash the amp. Oh... when replacing that cap, use one with a higher voltage rating than what is in there now. It might survive longer. OBSERVE POLARITY OF THE CAP WHEN INSTALLING SAME!

ok so i guess i will go get it fixed
do you think there is anyway to get crunch to fix or should i just cut my loses
also im sure i will be looking for a good amp to power these audiobahn subs have any suggestions
price would be 200-300$ maybe a little more
also should i go ahead and wire my subs in stereo instead of bridged on this amp
