Keep blowing Speaker amp....

Hey people, got an issue.
when i bought the car it came wid a legacy la690
the 4 speaker where wires to 2 set of wires *1 set power the left 1 set power the right*

so what happend was they where connected to this amp was a 4 channel bridge into 2. and the amp blew , one day. NO IDEA why legacy ew. yes i no!
so i replaced it and got a visonik to match ma v900xd sub woofer amp

So i install it had it for a good while. and today it ALSO blew went into protection mode and never wanna come out.

so i decide to test the speaker wires on each set (left and right) and they where giving me a 2.5 ohm reading.

AMP spec
# 300 Watt 2 Channel Amplifier
# RMS Power at 2 Ohms: 110 watts x 2 chan.
# RMS Power at 4 Ohms: 75 watts x 2 chan.
# Bridged RMS Power: 150 watts x 1 chan. at 4 Ohms


are my amps blowing because the speakers are wired to the wrong OHM?. or is something else blowing theses amps?

Thanks in advance.

Take it to a local shop and have them do a quick checkover of the system.

1 speaker might be blown, 1 wire might be crimped.. 1 speaker might have a coil that's hitting the pole-piece only under travel so you can't find etc.. find the problem first!!!!

yeah basically i dont no who did up the system like this, am just goona tear up the entire speaker wiring and run new wires from speaker to power source cuz the last guy who own this car did a **** poor job! like am fund of the basics and i never experience this b4.
but when i saw i could not find the wire harness of the speakerrs and all 4 speaker where wires to 2 wiring at the abck to the amp that the car came with. ... i was confuse


so amm tear it down and check all speakers and all that. the only think i was concern was the ohm load was 2.5 ohm load on each wires i test each wire has 2 speaker.*left front n back) n (right back and front)

oh welll goona search for a 4 channels amp and redo all teh wiring with proper gauge wiring the guy b4 use sum fine *** 20 gauge cant even split the ends without ripping the shielding of the wires.

THANK FOR THE HELP DO!
