Hi, my name is Denver, I have a Lanza Optic 500.2 amp
everytime i put the bass louder it blows the fuse, im using a 60Amp fuse,
In the owners manual says the amp(500.2) takes four 40amp fuses but my amp DON'T have any place for fuses, My main power fuse is a 60amp thats the one keeps blowing, Amp works perfect when it's soft.
Pls help me
Many thanks: Denver (S.A)
The reason your blowing fuses is the amp needs at the least a 150 amp fuse on the wire that runs to your bat. There are fuse blocks that you can put 4 40amp fuse and theres the high dollor ones that you can put all the way to 200amp. When you trun up your amp its drawing to much current for the little 40 amp fuse that you have and will blow it everytime. I recomend Running a 4 gage wire to bat and ground with same. Get you a 150 or above amp fuse from a car audio shop somewhere. anyway sounds like from what you decribed, theres nothing wrong with your amp just the wires and fuse are not big enouf to handle the current that your amp pulls.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

assuming all 3 subs are 3-4 ohms, running all 3 in parallel (the 3 positive leads all attach to the amp positive terminal, and all 3 speaker negative leads connect to the amp negative terminal) will bring you at or above 1 ohm, which the amp is capable of handling. With 1500 watts, you will want to use 8 gague power leads for the amp, 12 gague speaker cables, and an inline 120 amp fuse between the amp and the battery, within 1 foot of the battery.
to use the high level leads, you have to isolate the wires going to each speaker (if using 4 channel mode) or isolate the wires going just to the rear if you are using 2 channel mode. you have to strip a small piece of the insulation off each speaker wire, and run it into the amps high level input harness. if you dont have the high level input harness, you can get a 2 channel high level to rca adapter for around $20. basically, you are tapping into the signal to the stock speakers to feed music to the amp. make sure you get all your positives and negatives correct. brighter wires are usually positive; however you may be faced with sa speaker which uses a grey wire, and another grey wire- the second with a black line. you will have to, again, turn to internet research to determine which is positive and negative, if the colors are not obvious.
Replace your battery. It's dead I feel. You can try to fully charge it up but if you had to replace the fluid in the battery it does not sound good. Make sure your battery cables are tight and clean on both ends.
Did that just begin out of nowhere? IS the Dvd spinning, if you listen closely and the player is making noise as well? That would be the lens trying to get a read on it but if it's scratched (I'm sure you tried others) sometimes the lens just go bad out of nowhere...Mu original 500 Sony PS1 in 1998 lost its lens about 3 months in...I can't think of anything else right this moment....I hope you fix it...
Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Double check all connections .A thumbs up would be greatly appreciated if this answer is helpful to you.
RCA cables are the best way to get the audio from your head unit to the amp. If your head unit doesn't have RCA outputs, you might be able to use the speaker outputs of the head unit to connect to the "high power" or "high level" inputs of the amp, if the amp has such inputs (check your manual).
