[QUOTE="alan-31, post: 7924560, member: 623458"] Thanks for all the input, guys! I decided to work on it last weekend, got 12 gauge wire from Lowes and replaced the speaker wires. They were really flimsy basically (regular car speaker wires). I actually felt them warm up sometimes because they weren't able to carry the amps. I felt that made a slight difference. The new wire is awesome. It still slightly distorts/reduces at very high volumes but that's OK. Its still a good setup because without that subwoofer, there is no bass and with it, its pretty nice, if not perfect. I don't listen to very loud music any way. But if I do need to improve the system I'll come back to this thread to read the advice to see what I should do next. So yea, for now all I did is replace the wires. If I need to do more, I'll probably have to pay to have it checked out/diagnosed by an audio expert at the shop, because of the number of variables (Quality and setup of the: amp, subwoofer, enclosure, bass restoration unit, audio from the stock unit). Its still running both sides of the amps at 4 ohms, which is the recommended ohms. Yea I would think running the amp at its recommended would be better than hitting the boundaries (2 or 8ohms), which are accepted but maybe not as good. I guess I would have to do an audio test to check that and check the temperatures too. If I listen to fairly loud music on the highway, the amp gets really hot after 30 minutes - too hot to touch other than a brief brush. So yea it may be that I need a better amp. I had gotten this for $40 used on Craigslist. What I had been using before was a "Pyramid PB440X Super Blue Series", which was new for $25 and that was a really weak amp (got what I paid for). This Pioneer is much more powerful than that one and is good enough for me for now. I also did a test to make sure powering the 2nd coil is making a difference and yes it does. If the coils are wired oppositely, they cancel each other out and there's silence. I guess that could be a test to find out if the signals going are identical or not. If they are not, I would hear something. Its a cheap setup, most likely much weaker than what most of you have but its fine for me for now. I bookmarked this thread. Yea, thats my only amp. I have the bass restoration unit first though, which is sort of a pre-amp (nothing powerful, it just improves the bass level in the smaller original signal). It tries to fix the action of stock units reducing the bass at higher volumes and I feel that definitely makes a difference. It has both left and right but I wanted identical signals for both coils of the speaker so they act in perfect sync with no difference in the audio signals. Yea I need to get a better amp if I want more power. [/QUOTE]
