Offer car subwoofers for sale in your full-service installation shop to boost your bottom line. Some customers may want high-end equipment suitable for competition, while others just want to feel the bass during a long commute -- subwoofers are essential in either case.

Figure out what kind of car subwoofers your customers are likely to want. The most commonly purchased size is the 12 inch speaker, and brands like Kicker, JL and Boss are popular. Keep more of the popular items in stock and look for good wholesale deals, but whatever you do, make sure your selection is large enough to keep your customers happy.

1. Provide any size of subwoofer your customers could ask for. Obviously, you should have a greater inventory of the more popular car subwoofers.

2. Sell a discount car subwoofer to those who are looking for a nice sound to keep to themselves. Discount subs tend to not be as loud as name brands, and don't have a great range either. But if that's all your customer wants, give it to him.

3. Keep all the proper supplies on hand for car subwoofer installation, if you offer it. This includes items like wires, cables and installation tools.

Action Steps
The best contacts and resources to help you get it done

Offer different sizes of auto subwoofers

Depending on the sound your customers are looking for, you'll need to carry several different sizes of speakers. The size of the person's vehicle also has an impact on the size of speaker you can install. Most customers get subs between 8 and 15 inches in diameter.

I recommend: Car Audio Factory carries a selection of Kicker and Pioneer subwoofers. Offer the best enclosed subs from Crutchfield.

Keep your expenses in check with discount car subwoofers

Not everyone wants top-of-the-line equipment. For customers who are just looking for something for personal use (as opposed to competitions), discount speakers will do just fine. The purchase price will be lower for you as well, helping you maintain a good profit margin.

I recommend: Buy wholesale subwoofers at OnlineCarStereo.Com, which has the biggest selection of car audio equipment available online. Buy reputable Pioneers from Audio N More.

Make sure you have the right supplies for installing car subwoofers

You customers don't just come to you to buy car subwoofers, they trust you to install them in their vehicles as well. There's not a whole lot of supplies needed for installing these speakers, but you do need things like cables, butt connectors, soldering irons and crimping tools. You can also choose to sell this equipment to customers wanting to do the installation themselves.

I recommend: Stock up on spools of speaker wire from JCWhitney. Find four and eight ohm crossovers at Parts Express.
