Amp Problem

[BigRooster 10+ year member]

Hey everyone. Ok to start off with, I have a Sony Xplod XM-504Z 500 Watt 4 channel amp. It's got two channels for high and two channels for low. I have my Sony Xplod 6.5's and my power acoustick tweeters running off the highs at around half gain, and I have two 10 inch sony xplod subs (model number XSL100P5W) ran off the low channel on the amp. I have the low channel around half gain also. Ok here's my problem.. If I turn the amp up on the low channel to around 3/4ths the amp goes into protect, it does that when I go over half gain. I know gain isn't a volume knob but this amp should push out enough to bump these subs pretty good, and they're barely audible now. The highs are killer, but the lows are almost inaudible.... And I also have the amp bridged, and yes it is bridgeable, it has a diagram on the amp of how to do so. Why isn't the bass loud?? I'm pretty sure I have it wiredd at 2 ohm, they're 4 ohm SVC subs. I have the positive from the amp to the positive terminal on one sub, and from that sub's positive I have a wire ran to the positive terminal on the other sub. I have it the same exact way for the negative. Give me some feedback, help me if ya can. Thanks!

yea the amp is really poor quality also it's says in the specs it's only 50watts a channel the 500 your reading is an inflated peak rating.

I just read in the manual that it can be used as a bridging amplifier and have a max output of 250 watts. So it should push the subs better than they are now since I have it bridged, or does me having the highs hooked up have something to do with that? Like If I unhooked the mids and highs and ran them from the headunit would the bass be louder?

I hate to be the bearer of bad news, but that 250 peak is magnificently embellished by Sony. Rule of thumb is to look at the fuses on the amp, then divide that by four, that is what each channel will actually produce. If you have it bridged then you can add two channels together. But to be honest you might be getting 100 watts on those two subs

true that amp isnt very stong to handle that sub in order to get more bass u need a bigger amp

The amp goes into protect if I turn the gain higher than half on the rear sub channel with the 2 subs. I read the wattage isn't jsut to the sub, it's to the speakers too so that puts less to the subs. So what if I hook the speakers to the HU and the sub bridged to the rear channel on the amp, do you think it'd still go into protect and do you think it'd be louder?
