I have a 2004 Acura TL, I got a system put in March 5th 2010.
Kenwood Excelon X600F (100w rms X4)
Hifonics BXi1210D (1200w rms @1ohm mono)
(4) Polk audio DB5251 5.25" components (100w rms each)
(2) 10" JL Audio W3 Single voice coil (500w rms each)
Audio control Lc7 Line out converter
1.5 Capacitor
(both amp's gain set between 2 & 3 o clock position)

I had it proffessionally installed and they wired the mono amp with a 1ohm load (1200w rms @ 1 ohm) and the 4ch amp in with a 4ohm load (100wx4 @ 4ohm) I noticed they used a 4 gauge power with with a 100a agu inline fuse and a distribution block. the kenwwod uses 2 40a fuses and the hifonics uses 1 80a fuse, Since the installaion I have blown the inline fuse 4 times and I havent even raised the volume 3/4 of its maximum. On top of that, if I play it between 1/2 and 3/4 of its' max, my 4 channel will go into protection mode and come back on after about 30 seconds, you can see the amp's fan turn on when it goes into protection mode.

I googled the issue and it seems that the two amps require more power than the 100a inline fuse is allowing, I'm going to have them install a separate power wire for the kenwwod amp and have a 80a fuse installed on both power wires, I was curious if this would solve the issue with the blown inline fuses, also, could the lack of enough power cause the amp to go into proctection mode, if not, what could be cause the amp to go to protect mode. All the wiring was check by a different pro shop and they didn't find and shortage or bad ground. The system sounds freakin awesome and i cant even max it out to see what's the most it can do. This sucks, Please help

Current starving your amps can cause them to go into their protection mode.

I am a little supprised that at the 1/2 to 3/4 volume level you are having these problems. Usually music places a more modest current demand on amps and even though your 100A. in-line fuse looks like it will limit the current needed by your amps I am supprised that you are blowing big fuses like your 100A.

An easy way to verify that the problem is with the power supply wire is to disable one of your amps and see if you still have the problem.

Do you know how you have the capacitor wired into your power circuitry?

The power wire goes to the distribution block and then the mono amp. The 4ch amp is connected from the distribution block. I have no issued with the mono amp at all except when the inline fuse blows, everything goes dead. My max volume is 40 and the most I usually play it at is between 25 an 28 and if I leave it at 28 for a
couple days, kiss that fuse goodbye, the longest I went without blowing a fuse was a month and a half and then 2 weeks after replacing the fuse. My other issue is the 4 ch amp, I just can't see why it's going into protection mode, I'd expect the mono amp to act up especially being played at a 1ohm load but it's the 4ch that does it. I'm probably an intermediate when it comes to basic car audio, I've intalled 5 systems myself in my past cars and never had this issue. I decide to have the pro shop do this one since the Acura was a little too complicated for me but I never thought I'd be having this issue. I'm gonna have the the separate power line done for the interior amp and see if that wil solve 1 if not both problems.

I Meant that the power wire goes from the distribution block to the capacitor, then the mono amp. The 4ch is not wired to the capacitor.
