But my current system im having a really bad problem with blowing my amp. To begin with i have a 2000 ford f150, (with a i think i was told a 130 amp alternator and i was also told thats the biggest i could get by a local auto parts store) the truck is airbagged, i have 4 compressors that draw a MAX of 92 amps, when they are running, which isnt all the time. I installed a 2nd battery just to be safe, and make sure i wouldent have any power issues. Which i have not had any. I worried about installing a system and how it may be affected because my truck already uses soo much power. I decided to install it and see if i would have issues. First i installed 4 gauge power wire BUT theres a problem, im not sure IF it could cause the amp to blow, but I had 2 pieces of 4 gauge wire and could not afford to buy a solid piece so i fount a power block, if you will for 4 gauge wire, its made of aluminum, i put the wire in it and taped it up really good with electrical take so it could not be grounded out or get wet, then finished running it. Also i did not install a fuse from the battery, i wasnt sure what size fuse to get or how important it is to have. I have a ANL style fuse laying around from a previous install, but its 150 amps and i thought that would have been too much i wasn't sure. Now i installed 2 15 inch subs there power acoustik's 1000rms each 2000 peak each. dual 4 ohms ( just in case you need to know the model# there power acoustik fx-15) They are in seperate chamber ported boxes that are a little over 3.50 cu. ft. The subs are recommended for 3.50 but i checked and the manufacturer said it was fine. I at first bought a boss amp that is now discontinued. It was the Boss IQ3KD.1 Class D Monoblock Amp, it said it pushed 2100 RMS and 3000 Peak at 1 ohm. IT had 3 X 30 Amp fuses built in. I figured its a little lower than what the subs can take, but i didnt want to blow the subs if anything. I wired the subs parallel to acheive the 1 ohm. I did not install a capacitor. Ground wire was also 4 gauge straight to the body. Ok so i hooked everything up, and the system worked great for about 3 days, (of course i was still breaking it all in) all of a sudden out of no where it all cut out and quit working. I thought maybe i had blown the subs but after testing fount out the amp blew. Now like i said the amp does have fuses, but none of them ever blew, I thought MAYBE a defective amp? Well it did have a warranty. I sent it back but they did not have any more in stock it was the last one so i decided to get another amp. This time i got a Lanzar Vibe3100D amp it says it will do 1800 rms in a 1 ohm load and 3000 peak. It has 5 X 30 amp fuses. A little bit lower rms but i wanted another amp to get my system working.

[QUOTE="Dal33tdude12, post: 1587952, member: 566964"] I was not sure whether to post this in the amp section or electrical section i apologize if i posted it in the wrong section. Some of the questions i am going to ask may be stupid but please bare with me. I have installed a few systems by trial and error and have gotten most of it correct with no issues. But my current system im having a really bad problem with blowing my amp. To begin with i have a 2000 ford f150, (with a i think i was told a 130 amp alternator and i was also told thats the biggest i could get by a local auto parts store) the truck is airbagged, i have 4 compressors that draw a MAX of 92 amps, when they are running, which isnt all the time.
