This is a review of the XGT-V4, a "slower" version of the XGT-Z. Performance is bad in wet weather; deadly in snow, ice, or slush. Treads are 2/3 gone in 22000 miles. I crashed my car on these tires because I spun out in light rain. Don't buy unless you live in sunny and dry climate. Aurora Pro Mobile Mechanic

I recommend this subwoofer to anyone who just wants clean,loud output bass on their vehicle or either to compete on eXtreme, (keep in mind that since they are 300W R.M.S., you need at least 8 to beat everybody outthere, even the JL Audio 12W6v2). RPM Meridian Towing & Recovery

I listened to alot of amps over a 6 month period of time. I was first going to buy a McIntosh amp, but when I heard the 604X driving some Diamond Audio Hex, Henderson Trailer Repair
